In 1882, Nikola Tesla made an important discovery: the rotating magnetic field. Tesla later pioneered the use of a rotary field of force to operate machinery. He exploited the principle to design a unique two-phase induction motors in 1883. In 1885, Galileo Ferraris independently researched the very same concept. Ferraris published his research in a paper in 1888, to the Royal Academy of Sciences in Turin. In Tesla's published articles, he had suggested that the commutators from a machine could be removed and the device could operate on a rotary field of force. Professor Poeschel, Tesla's teacher, stated that would be akin to building a perpetual motion machine. This classic alternating current electro-magnetic motor was the beginning of the induction AC motors. Michail Osipovich Dolivo-Dobrovolsky later invented a three-phase "cage-rotor" in 1890. These types of AC motors are now used for the vast majority of commercial and industrial applications.

A typical AC motor consists of two parts:
• An outside stationary stator having coils supplied with AC current to produce a rotating magnetic field, and;
• An inside rotor attached to the output shaft of AC Motors that is given a torque by the rotating field.

The AC Motors come in two different types known as Induction and Synchronous. These AC Motor types are determined by which rotor is used in the construction.

Induction AC Motors
Induction AC Motor products can be referred to as asynchronous motors or rotating transformers. These types of AC Motors use an electromagnetic induction to power the rotating device which is usually the shaft. The rotor in Induction AC Motors typically turns slower than the frequency that is supplied to it. Induced current is what causes the magnetic field that envelops the rotor of these motors. These Induction AC Motors can come in one or three phases.

Synchronous AC Motors
The Synchronous Motors are typically AC Motors that have their rotor spinning at the same rate as the alternating current that is being supplied to it. The rotor can also turn at a sub multiple of the current it is supplied. Slip rings or a permanent magnet supplied with current is what generates the magnetic field around the rotor.

AC Motors are a reasonable cost effective solution to your application needs. The construction materials along with how the motor is designed make AC Motors an affordable solution. The AC Motors operate with a rotating magnetic field and does not use brushes. This enables the cost of the motors to be lower and eliminates a piece of your motor that wears over time. AC Motors do not require a driver to operate. This saves initial setup costs. Today's manufacturing processes makes producing AC Motors easier and quicker than ever. The stator is made out of thin laminations that can be pressed or punched out of a machine. Many other parts can be quickly made and perfected saving both time and money.

AC Motors have two options for feedback controls. These options are either an AC Motor resolver or an AC Motor encoder. Both the AC Motor resolver and the AC Motor encoder can sense direction, speed, and the position of the output shaft. While both the AC Motor resolver and AC Motor encoder offer the same solution in multiple applications, they are greatly different.

AC Motor resolvers use a second set of stator coils called the transformer to provoke rotor voltages across an air gap. Since the resolver lacks electronic components, it is very tough with a large temperature range. The AC Motor resolver is also naturally shock resistant due to how it is designed which makes it most likely used in harsh environments.

The AC Motor optical encoder uses a shutter that rotates to disrupt a beam of light that crosses the air gap between a light source and the photo detector. The rotating of the shutter over time causes wear on the encoder. This wear reduces the durability and dependably of the optical encoder.

The type of application being run will establish whether a resolver or an encoder is needed. AC Motor encoders are easier to implement and are more exact so they should be the primary preference for any application. A resolver should only be chosen if the durability needs and the environment in which it will be used requires it.

AC Induction motors have been in the industry for over 20 years now. The idea behind AC Motors came from Nikola Telsa in the 1880's. Nikola Telsa stated that motors do not need brushes for the rotor to commutate. He said they could be induced by a rotating magnetic field. Nikola Telsa identified the use of alternating current which induced rotating magnetic fields. Telsa filed the U.S. patent number 416,194 for his work on AC Motors. This type of motor is what we call an AC Induction motor today.

AC Motors have made a name for itself by having a simple design, being easy to use, having a simple rugged construction and being cost effective for many different applications. Advances in technology have allowed manufacturers to build up Telsa's idea and have allowed a great versatility in the speed control of AC Induction Motors. From a simple phase control to more robust closed loop systems that use vector oriented field controls; AC Motors have advanced over the last one hundred and twenty years.

There is a vast selection of accessories for AC Motors. The accessories available include a brake, clutch, fan, connector, and cables.

The AC Motor brakes are a 24vdc system. These brakes are ideal for any holding applications you may use with AC Motors. The AC Motor brakes have a low voltage design for applications that are susceptible to weak battery, brown out, or long wiring.

The AC Motor Clutch is used to control the torque that is applied to the load. The AC Motor clutch can also be used to ramp up the speed of a high inertia load. Clutches are ideal to use with AC motors when you want precise control over torque or to slowly apply the power. AC Motor clutches also help prevent large current spikes.

AC Motor Fans are used to cool down the motors. They are not really seen in small motors because they are not needed but more common with larger AC induction motors due to heat generation. There are two types of fans that are used for AC Motors. The types are internal and external fans. AC Motor fans are ideal to use when overheating is a concern.

AC Motor cables can be custom made with the supplied AC motor connector to fit your specifications. The cables may also be purchased from Anaheim Automation.

Anaheim Automation was established in 1966 as a manufacturer of "turnkey" motion control systems. Its' emphasis on R&D has insured the continued introduction of advanced motion control products, such as the AC Motors product line. Today, Anaheim Automation ranks high among the leading manufacturers and distributors of motion control products, a position enhanced by its excellent reputation for quality products at competitive prices. The AC Motors product line is no exception to the Company’s goal.

Anaheim Automation offers a variety of standard AC Motors. Occasionally, OEM customers with mid to large quantity requirements prefer to have AC Motors that are custom or modified to meet their exact design requirements. Sometimes the customization is as simple as shaft modification, brake, oil seal for an IP65 rating, mounting dimensions, wire colors, or label. Other times, a customer might require that AC Motors meet an ideal specification such as, speed, torque, and/or voltage.

The most common and simple industrial motor is the three-phase AC induction motor, sometimes shortened to AC Motor. Pertinent information can be found about AC motors by checking the nameplate.

Advantages of Using AC Motors

• AC Motors are of a simple design
         • The simple design AC motors: Simply stated, a series of three windings in the exterior stator section with a simple rotating section (rotor). The changing field caused by the 50 or 60 Hertz AC line voltage causes the AC motor rotor to rotate around the axis of the motor.
         • The speed of AC motors will depend upon these three variables:
                   1. The fixed number of winding sets (poles) built into AC motors, which determines the motor's base speed.
                    2. The frequency of the AC line voltage. Variable speed drives change this frequency to change the speed of AC motors.
                    3. The amount of torque loading on AC motors, causes slipping.
• AC Motors are of a low cost construction
AC motors have the advantage of being the lowest cost motor. AC motors are perfect for applications requiring more than about 1/2 hp (325 watts) of power. This is due to the simple design of AC motors. For this reason, AC motors are generally preferred for fixed-speed applications, such as in industrial applications and for commercial and domestic applications where AC line power can be easily attached. Over 90% of all motors are AC induction motors. They are found in air conditioners, washers, dryers, industrial machinery, fans, blowers, vacuum cleaners, and many, many other applications.

• AC Motors operate reliably
The very simple design and construction of AC motors casue them to be extremely reliable and are considered to be low maintenance. Unlike DC Brush Motors, there are no brushes to replace. If AC Motors are used in the appropriate environment, protected by an enclosure, AC motors can expect to replace the bearings after several years of continuous operation. If the application is well designed in a protective environment, AC motors may not require the bearings to be replaced for more than 10 years.

• Easily Found Replacements
The wide use of AC motors in many different industries has resulted in easily found replacements for existing equipment repairs and/or upgrades. Many manufacturers adhere to either European (metric) or American (NEMA) standards.
• AC Motors are made by many manufacturers , so it is relatively easy to obtain replacements (for basically the same motor)
• AC Motors are designed in a variety of mounting styles (dependent upon the motor manufacturer). Foot Mount, C-Face, Large Flange, Vertical and Specialty.
• There are many environmental styles available for AC Motors, to cover a wide range of applications and industries, called Specialty AC Motors by most. Because of the wide range of environments in which people want to use AC motors, manufacturers have adapted by providing a wide range of packaging/enclosure designs, such as Open Drip Proof (ODP), Totally Enclosed/Fan-Cooled (TEFC), Totally Enclosed/Air-Over (TEAO), Totally Enclosed/Blower-Cooled (TEBC), Totally Enclosed/Non-Ventilated (TENV), and Totally Enclosed/Water-Cooled (TEWC) versions.

Disadvantages of Using AC Motors

• Expensive speed control - Speed controllers can be expensive. The electronics required to handle an AC inverter driver are considerably more expensive than those required to handle a DC motor. However, if performance requirements can be met ~meaning that the required speed range is over 1/3rd of base speed ~ AC inverters and AC motors are usually more cost-effective overall, than are DC motors and DC drives. This is especially true for applications larger than 10 horsepower, because of cost savings in the AC motor.
• Inability to operate at low speeds - Standard AC motors should not be operated at speeds less than about 1/3rd of the base speed, due to thermal considerations. A DC motor should be considered for these applications.
• Poor positioning control - Positioning drivers and controllers can be expensive and crude. Even a vector drive is very crude when controlling a standard AC motor. Stepper motors and Servo Motors are more appropriate for applications wherein positioning and speed control is critical.

The following environmental and safety considerations must be observed during all phases of operation, service and repair of AC Motors system. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the AC Motor. Please note that even well-built AC Motors operated and installed improperly, can be hazardous. Precaution must be observed by the user with respect to the load and operating environment. The customer is ultimately responsible for the proper selection, installation, and operation of an AC Motor.

The atmosphere in which AC Motors are used must be conducive to good general practices of electrical/electronic equipment. Do not operate the AC Motors system in the presence of flammable gases, dust, oil, vapor or moisture. For outdoor use, AC Motors must be protected from the elements by an adequate cover, while still providing adequate air flow and cooling. Moisture may cause an electrical shock hazard and/or induce system breakdown. Due consideration should be given to the avoidance of liquids and vapors of any kind. Contact the factory should your application require specific IP ratings. It is wise to install the AC Motors in an environment which is free from condensation, electrical noise, vibration and shock.

Additionally, it is preferable to work with the AC Motors system in a non-static protective environment. Exposed circuitry should always be properly guarded and/or enclosed to prevent unauthorized human contact with live circuitry. No work should be performed while power is applied.

Do NOT plug in or unplug when power is ON. Wait for at least 5 minutes before doing inspection work on the AC Motors system after turning power OFF, because even after the power is turned off, there will still be some electrical energy remaining in the capacitors of the internal circuit of the AC Motors system.

Plan the installation of the AC Motors in a system design that is free from debris, such as metal debris from cutting, drilling, tapping, and welding, or any other foreign material that could come in contact with system’s circuitry. Failure to prevent debris from entering the AC Motors system can result in damage and/or shock.

The following information is intended as a general guideline for the installation and mounting of AC Motors system. WARNING - Dangerous voltages capable of causing injury or death may be present in the AC Motors system. Use extreme caution when handling, testing, and adjusting during installation, set-up, and operation. It is very important that the wiring of AC Motors be taken into consideration upon installation and mounting. Subpanels installed inside the enclosure for mounting system components, must be a flat, rigid surface that will be free from shock, vibration, moisture, oil, vapors, or dust. Remember that the AC Motors will produce heat during work, therefore, heat dissipation should be considered in designing the system layout. Size the enclosure so as not to exceed the maximum ambient temperature rating. It is recommended that AC Motors be mounted in position as to provide adequate airflow. AC Motors should be mounted in a stable fashion, secured tightly.

NOTE: There should be a minimum of 10mm between AC Motors and any other devices mounted in the system/electric panel or cabinet.

NOTE: In order to comply with UL and CE requirements, the AC Motors system must be grounded in a grounded conducive enclosure offering protection as defined in standard EN 60529 (IEC 529) to IP55 such that they are not accessible to the operator or unskilled person. As with any moving part in a system, the AC Motors should be kept out of the reach of the operator. A NEMA 4X enclosure exceeds those requirements providing protection to IP66. To improve the bond between the power rail and the subpanel, construct your subpanel out of zinc-plated (paint-free) steel. Additionally, it is strongly recommended that the AC Motors system be protected against electrical noise interferences. Noise from signal wires can cause mechanical vibration and malfunctions.

The following information is intended as a general guideline for wiring of Anaheim Automation AC Motors. Be aware that when you route power and signal wiring on a machine or system, radiated noise from the nearby relays, transformers, and other electronic devices can be inducted into the AC Motors and encoder signals, input/output communications, and other sensitive low voltage signals. This can cause systems faults. WARNING - Dangerous voltages capable of causing injury or death, may be present in the AC Motors system. Use extreme caution when handling, wiring, testing, and adjusting during installation, set-up, tuning, and operation. Don’t make extreme adjustments or changes to the AC Motors system parameters, which can cause mechanical vibration and result in failure and/or loss. Once the AC Motors system is wired, do not run by switching On/Off the power supply directly. Frequent power On/Off switching will cause fast aging of the system components, which will reduce the lifetime of AC Motors system.

Strictly comply with the following rules:

• Follow the Wiring Diagram with each AC Motor
• Route high-voltage power cables separately from low-voltage power cables
• Segregate input power wiring and AC Motors power cables from control wiring and motors feedback cables. Maintain this separation throughout the wire run.
• Use shielded cable for power wiring and provide a grounded 360 degree clamp termination to the enclosure wall. Allow room on the sub-panel for wire bends.
• Make all cable routes as short as possible.
NOTE: Factory made cables are recommended for use in our AC Motors systems. These cables are purchased separately, and are designed to minimize EMI. These cables are recommended over customer-built cables to optimize system performance and to provide additional safety for the AC Motors system and the user.

WARNING - To avoid the possibility of electrical shock, perform all mounting and wiring of the AC Motors prior to applying power. Once power is applied, connection terminals may have voltage present.

Typically, AC Motors consist of two main components: the stator and the rotor. The stator is the stationary part of AC motors, consisting of several thin laminations wound with an insulated wire, forming the core. The rotor is connected to the output shaft on the inside. The most common type of rotor used in AC Motors is the squirrel cage rotor, named after its resemblance to rodent exercise wheels.

The stator mounts inside the AC motor’s enclosure, with the rotor mounted inside, and a gap separating the two from touching each other. The enclosure is the motor’s frame, containing two bearing houses.

What Industries are AC Motors used in?

AC Motors are primarily used in domestic applications due to their relatively low manufacturing costs, and durability, but are also widely used in industrial applications.

What Applications are AC Motors used for?

AC Motors can be found in numerous home appliances and applications, including:
- Clocks
- Power tools
- Disk drives
- Washing Machines and other Home Appliances
- Audio turntables
- Fans

They can also be found in industrial applications:

- Pumps
- Blowers
- Conveyors
- Compressors

Preventative maintenance is the key to long-lasting AC Motors. Routine inspection should be implemented. Always check AC Motors for dirt and corrosion; dirt and debris can clog air passages and reduce airflow, ultimately reducing insulation life and possible motor failure. When debris is not blatantly visible, check to ensure air flow is steady and not weak. This could potentially point towards clogging as well. In wet environments, check for corroded terminals in the conduit box and repair when necessary.

Listen for excessive noise or vibration, and feel for excessive heat. This could indicate lubrication of the bearings is needed. Note: Be cautious when lubricating the bearings as excessive lubrication may lead to dirt and oils clogging air flow. Be sure to locate and remove the source of heat for AC motors to avoid system failure.

In order to select the appropriate AC Motors for your application, first you need to determine basic specifications. Calculate the required load torque and operating speed. Remember that induction and reversible motors cannot be adjusted, they require a gearhead. If this is needed, select the appropriate gear ratio. Next determine frequency, and power supply voltage for AC motors.

The fundamental operation of AC Motors relies on the principles of magnetism. Simple AC Motors contain a coil of wire and two fixed magnets surrounding a shaft. When an electric (AC) charge is applied to the coil of wire, it becomes an electromagnet, generating a magnetic field. Simply described, when the magnets interact, the shaft and the coil of wires begin to rotate, operating AC motors.

Always ensure the PMDC motors, as well as the motor environment is kept clean, preventing the motor from potentially encountering any type of dirt, oils, or debris. All mounting bolts should be kept tight, and the operation of the motor is in accordance with the given instructions on installation. PMDC Motors generally tends to have increased maintenance requirements in comparison to those of AC motors, because many of the motor’s components are constantly coming in contact with one another. Over time, the brushes will wear and will require replacement. Also, the interaction between the commutator and the brushes will cause debris and contaminants to settle within PMDC motors, that require cleaning up after. Most commonly this occurs between the commutator and the shaft of PMDC motors, as well as between the winding and the armature.

Consumer Electronics Although a BLDC motor may perform the same functions originally fulfilled by brushed DC motors, cost and control complications prevent a BLDC motor from completely replacing brushed motors. However, BLDC the motor has monopolized many areas of the consumer electronics industry, and are used in many different locations, including computer hard drives and CD/DVD players. A BLDC motor is used to operate the small cooling fans that are located in electronic equipment as well. Cordless power tools also utilize a BLDC motor because the need for increased efficiency of the BLDC motor allows for long periods of use before needing to recharge the battery. Furthermore, direct-drive turntables for ?analog? audio disks use a low-speed, low-power BLDC motor. Transport Electric and hybrid vehicles use a high power BLDC motor that are essentially AC synchronous with permanent magnet rotors. A BLDC motor is used in Segway and Vectrix-Maxi-Scooters also. Electric bicycles sometimes build a BLDC motor into their wheel hubs, with the stator solidly fixed to the axle and magnets attached to and rotating with the wheel. These electric bicycles have a standard bicycle transmission with pedals, sprockets, and chain that, if needed, can be pedaled along with or without the use of the BLDC motor. Heating and Ventilation It has become a popular trend to switch from AC motors to a BLDC motor (EC) because of the dramatic reduction in power needed o run them, versus the typical AC motor. Although shaded-pole and permanent split capacitor motors were the primary fan motor of choice, many fans today are being run by a BLDC motor. Some use a BLDC motor simply to increase system efficiency as a whole. Certain HVAC systems use ECM motors (electronically commutated BLDC motors). Particularly these are the HVAC systems that feature load modulation and/or variable-speed. A BLDC motor does not only have higher efficiency, but also a built-in microprocessor that allows for better airflow control, programmability, and serial communication. Model Engineering and Hobbyists The most popular motor choice for model aircraft today is the BLDC motor. The BLDC motor is available in a wide array of sizes, and have a favorable power to weight ratios. A BLDC motor has transformed the market of electric-powered flight. The introduction of the BLDC motor has displaced the use of almost all brushed electric motors in model aircraft and helicopters. Modern batteries and BLDC motor products allow model airplanes to vertically ascend, versus gradually climb. Small glow fuel internal combustion engines that were used in the past are no comparison to the silent and clean BLDC motor products. BLDC motors have also increased in popularity among the Radio Controlled (RC) cars, buggies, and trucks, where sensor-type BLDC motors allow the position of the rotor magnet to be detected. Many BLDC motors feature upgrades and replaceable parts like sintered neodymium-iron-boron (rare earth magnets), replaceable motor timing assemblies, and ceramic bearings. As a result, these BLDC motors are quickly ascending to the top of the list as far as preferred motor types for electric on and off-road RC racers. BLDC motors have low-maintenance, high reliability and power efficiency ~ most BLDC motors with an efficiency rating of 80% or more.

For low-speed applications it is highly recommended to use an encoder for the feedback rather than the Hall sensors. The Hall sensor counts per revolution can only be as great as a number of polls times the quantity of Hall Sensors. The high count that is calculated by the BLDC Motor controller can be used to its advantage when operating a BLDC Motor. The BLDC Motor controller can more precisely control the velocity by utilizing the additional information from the BLDC Motor. The higher the resolution on the encoder to more finely the BLDC Motor controller can control the BLDC Motor. Even though the expense is much greater for encoders when compared to Hall sensors this price can be justified as it can result in very precise control for a much lower cost than alternative technologies such as Servo motors were AC motors or synchronous motors.

For low-speed products it is advised to use an encoder for the feedback rather than the Hall sensors. The number of counts per revolution for the Hall sensor can only be as large as the number of polls times the number of Hall Sensors. The BLDC Motors controllers can use this higher count to its advantage when operating the BLDC Motors. The BLDC Motors controllers can use the extra information with more counts per revolution at its disposal for more accurate control of the velocity. The BLDC Motors controllers can more finely control the BLDC Motors with a higher resolution on the encoder. Though when evaluating prices yes the encoder is more costly than the Hall sensor, but with the encoders you receive precise control at a lower cost than alternate technologies such as AC motors, Servo motors, or Synchronous motors.
