Frequently Asked Questions
Why is the stepper motor size important? Is it possible to just choose a large motor size?
The stepper motor size is important because if the motor’s rotor inertia predominately consists of the load, resonance increases and poses vibration and acceleration issues. Also, larger rotors require more time to accelerate and decelerate and are more costly. Therefore it is important to choose a motor size dependent on the criteria for user application.

What temperatures are stepper motors able to run at?
Most stepper motors include Class B insulation. This allows the motor to sustain temperatures of up to 130° C. Therefore, with an ambient temperature of 40° C, the stepper motor has a temperature rise allowance of 90° C allowing for stepper motors to run at high temperatures.

Is it possible to get more torque by running the stepper motor at double its rated current?
It is possible to increase torque by increasing the current but by doing so, it weakens the motor’s ability to run smoother and will also make the temperature of the motor rise. Please make sure to not run the stepper motor above the internal tempearture of its class rating.

What is the difference between four, six and eight leads in motors?
4 and 6 lead stepper motors are considered 2 phase motors. 8 lead stepper motors are considered to be 4 phase steppers. 4 lead motors can be wired in bipolar series connection only 6 lead motors can be wired in bipolar series, bipolar half-coil or uniploar connections 8 lead motors can be wired in bipolar series, bipolar half-coil, biploar parallel or uniploar connections.

What is the difference between a closed-loop stepper motor controller and an open-loop stepper motor controller?
In an open-loop stepper motor controller, no feedback is going from the motor to the controller. This type of controller is effective when the motor is carrying a constant load at a steady speed. In a closed-loop motor controller, a feedback signal is provided from the motor. Closed-loop control can be useful in applications where load or speed varies along with positioning verification. In comparison to the closed-loop controller, the open-loop controller lacks complexity and is more affordable.

When should I use microstepping?
Microstepping should be used when the Stepper motor is operated at or around resonance frequencies, when you are experiencing noise, vibration problems or to increase step accuracy.

What is the recommended cable distance between Anaheim Automation stepper motors and drivers?
We recommend that the wiring between stepper motors and drivers not exceed 25 feet. Although it is not required, we suggest using Anaheim Automation shielded motor cable. This cable is ideally suited to handle all driver and motor combinations that we offer. We can also add connectors to the cables. Please contact an Applications Engineer for more details.

If I apply too much load to a stepper motor which causes the shaft to stop rotating, will I damage the motor?
No. The stepper motor will just stall and the rated current that the driver is controlling will still be flowing through the coils. Unlike a DC motor, the current will not rise when a step motor is stalled.

What is the life expectancy of Anaheim Automation Stepper Motors?
Anaheim Automation stepper motors life expectancy is mainly based on the bearings. The majority of Anaheim Automation stepper motors contain ball bearings providing 20,000 plus hours life expectancy under normal operating conditions. Anaheim Automation’s warranty is 12 months after the invoice date. See the “Environmental Conditions” sections of the stepper motor guide for more details.

Does Anaheim Automation have Permanent Magnet Stepper Motors?
Yes. In size ranging from 15 to 57 mm in diameter, with torque ranges of 1 to 23 oz.-in. (model dependent). See PM Stepper Motors under the Stepper Motor category on our web site for more details and product specifications.

Can I order a stepper motor with 3% accuracy instead of 5%?
Because almost all of our 5% rated stepper motors fall into the 3% accuracy category, we usually recommend that you order our standard motors. If you require a “guarantee” for the 3% accuracy, contact the factory for assistance.

Are stepper motors with optional conduit box, keyway, encoder-ready features considered "special"?
Yes, they are considered a "special", non-stock item and may require a NRE or SET-UP charge. There is an additional cost for some changes as well. Many stepper motor series already have shaft-flat and encoder-ready provisions. Check the specification sheet for more details. Some stepper motor series include a conduit (terminal) box. The shaft flat and encoder-ready motors do not incur an extra cost (if it’s already a feature of that series). Motors with conduit boxes will cost more than the standard motors. See individual dimension drawings for details.

Does Anaheim Automation make stepper motors with drivers attached?
Yes. Anaheim Automation offers a line of Integrated Stepper Motors with Drivers and/or Controllers, in NEMA sizes 17, 23 and 34.Check our 17MD, 23MD, and 34MD series for Integrated Motor/Drivers, and our 17MDSI and 23MDSI series for our Integrated Motor/Driver/Controller product lines.

Can I purchase an IP65 rated Stepper Motor?
Yes. Anaheim Automation offers a IP65 version for NEMA sizes 17, 23, 34 and 42 frame stepper motors, torque ranges from 35 to 5,700 oz.-in.(model specific). Visit our web site under Stepper Motors, and search IP65 motors.

What types of applications are encoders implemented in?
Encoders are frequently used in stepper motors, automation, robotics, medical devices, motion control and many other applications requiring position feedback.

Will Anaheim Automation mount an encoder to a motor?
Yes. First, choose from Anaheim Automation's extended line of stepper and brushless motors. Second, select the appropriate encoder adder part number from our selection of single-ended and differential encoders which can be found in our 'Encoder Adders' section, and add it to the end of your Anaheim Automation motor part number. Its that simple!

What is the lifetime of Anaheim Automation’s motors and gearboxes?
Under normal operating parameters, Anaheim Automation's Stepper and BLDC Motors and gearboxes have rated lifetimes of 20,000 hours.

Do I need to purchase a cable with my stepper motor and driver purchase?
We do recommend purchasing the applicable cables. However, when installing a stepper motor, driver and/or controller, it is not necessary to purchase the cables from Anaheim Automation if the user is careful in their selection of wires and connectors. Be sure to inspect all terminal blocks and connectors, and check cabling/wiring for accuracy. Choose the correct wire gauge for the distance (cable length) to make certain it is sufficient. Whenever possible, use Anaheim Automation’s cables, as they are matched to the specific products, and contain a shield to help prevent electrical noise in the motion system. A poorly wired system can cause intermittent and erratic stepper motor function, and in some cases, can do damage to the electronics. NOTE: Do not match your cable wires to the gauge size of the step motor lead wires, this is a common mistake.

I am experiencing intermittent problems with my stepper motor performance. What should I look for in solving the problem?
Intermittent problems are the most common and the most difficult to detect. Start by checking the wiring and connectors used between the stepper motor driver and/or controllers. Are the screws tight? Are there any frayed wires? Do the terminals look discolored in any way, suggesting a loose connection and/or sparking? If you certain of your connections, contact Anaheim Automation. If under warranty (within 12 months from the original Invoice date) return it for inspection and test. If not, Anaheim Automation can evaluate the products we sold. Contact the factory for the charges and for a Return Materials Authorization (RMA) before returning. A form can be found on our web site.

I need a little more torque in my stepper motor system, but do not want to use a gearbox because of the added expense. What do you suggest?
First, determine what type of stepper motor you are using? Square-bodied stepper motor will deliver much more torque per NEMA size and stack lengths, than do their round-bodied (standard, legacy) type motors. The most torque for the frame/stack will be found in the K series, which is available only in NEMA 34 and 42 frame sizes. If you can go a little longer in size (up a stack length), that may be enough added torque. If you cannot fit a longer motor, but can fit a wider motor, then perhaps that is an option for you. Refer to our Stepper Motor Selector program found in our stepper motor intro on our web site.

I need a replacement stepper motor fast, and was told that you do not have stock on the part number I need. Do you have any other options? Rebuilt motors?
We almost always have other options to get a customer up and running. We do not sell “rebuilt motors” but we can make some other suggestions such as: can you accept the double-ended shaft version? How are you wiring the motor? Perhaps another motor in the same torque range will work? Maybe we have the same motor in a different wiring configuration? Conduit box versions? IP65 versions? If you can be somewhat flexible, Anaheim Automation can almost always ship from stock a replacement stepper motor. Contact our Application Engineers to discuss the critical parameters and those that can be flexible?

I already purchased an eight-lead stepper motor 23Y106S-LW8. I have seen your 23MD106 integrated motor/driver series, and think that is a better solution for my application. Can I just purchase the driver and add it to the motor myself?
No. Unfortunately, the stepper motor that is used in the integrated stepper motor/driver is not the same as the 23Y106S-LW8. Functionally, it will perform the same, but the hook-up and mounting specifications are different. We will accept the 23Y106S-LW8 for return if in resalable condition, offer a credit when the 23MD106 series is purchased.

I would like to add an encoder to my stepper motor. What is the advantage of purchasing the motor and encoder from Anaheim Automation?
It's up to the needs of the customer. Anaheim Automation sells these components separately, or already assembled, as a stepper motor “adder.” Typically, when both components are in stock, the lead time is under 72 hours to mount the encoder. If you have an URGENT request, then you may want to install the encoder yourself. You will need a tool to install, part number ENC-CTOOL-"BORE SIZE in inches". Most customers prefer that we add the encoder for them, as this ensures that it is installed correctly.

Why does my stepper motor run hot?
Under normal operating conditions, stepper motors will run “hot.” Always include adequate airflow in your stepper motor/driver system. Check the individual specification sheet for the stepper motor to be certain it is in the normal temperature range. If not, consult Anaheim Automation’s Application Engineers.

I need to add a gearbox to a stepper motor. How do I go about it?
Because motor manufacturer's specifications vary, the best way to select a gearbox for your stepper motor is to refer to our drawing, AA5210, Required Motor Data To Mount Gearboxes, to verify critical dimensions and optional features required. The link for this Data drawing is located on each gearbox page. You may also contact an Application Engineer for further assistance.

I need to add a gearbox to a stepper motor that I have purchased from another company. How do I go about it?
Because motor manufacturer's specifications vary, the best way to select a gearbox for your stepper motor is to refer to our drawing, AA5210, Required Motor Data To Mount Gearboxes. By filling out this forum and sending it to an Anaheim Automation Applications Engineer, they will be able to verify all dimensions and create a special part number for you to order.

Can I order stepper motors with encoders added? How do I go about it?
Yes. Encoders can not only be added to stepper motors, but brushless motors as well. Please refer to our Encoders located under Accessories on our web site. Anaheim Automation offers a line of single-ended or differential incremental rotary encoders. These encoders are available in sizes to cover NEMA 08 to 42 motors. These encoders have the capability to track from 0 to 100,000 cycles per second, with options of 32 to 2,500 cycles per revolution, with or without index features. Encoders are configured as motor adders, for dual shaft motors, or can be purchased separately, located on our Encoder web pages. Encoder cables are available, but also purchased separately.

Can I order a LS series table with my choice of stepper motors ? How do I go about it?
Yes, somewhat. We offer several stepper motor options with the LS100 series. Refer to the Ordering Information Chart for motor options and to complete the LS100 part number. Please note that T-Nuts are purchased separately.

How long does it take to get a custom stepper motor designed?
It depends on the customization of the stepper motor. For simple and straight forward such as a shaft modification, cable length change or connectors added to the motor, then it typically adds only a week to 10 days to the manufacturing cycle, which is 9 – 12 weeks, ARO. For a quicker turnaround time, a Premium Shipping Method can be added for the motor sub-assemblies, but this will only reduce the lead time by 2 – 4 weeks, making it a 5 – 10 week lead time. Contact an Anaheim Automation Customer Service representative for more details.

We have Cross Reference lists on our web site, or you may contact an Anaheim Automation Customer Service representative for more details.

Can Anaheim Automation cross an Automation Direct stepper motor?
Yes. For many stepper motors models, Anaheim Automation has a good cross for the Automation Direct high-torque stepper motors. We have Cross Reference lists on our web site, or you may contact an Anaheim Automation Customer Service representative for more details.

Can Anaheim Automation stepper motors be made with connectors coming out of the motor body?
Yes, and it is already available in some stepper motor models, but considered “special.” Please contact an Anaheim Automation Customer Service representative for more details.

Can I run a stepper motor and driver system outdoors?
Yes, but care must be taken, in that the stepper motor system must be well protected against the elements. You may need to upgrade to a higher IP rating as well. Consult with an Applications Engineer or refer to our Product Guides under Environmental Considerations for more details.

When designing a stepper motor and driver system, what should I start with – the motor or the driver?
Define the motor requirements first. There are several important criteria involved, such as the desired mechanical motion created by the stepper motor, the speed required for the motion, the load characteristics, the stepper mode and wiring configurations. More detailed information can be found in our Stepper Motion Guide on our web site. We also have a Motor Selector in the stepper motor section to help you select an exact stepper motor.

Are stepper motors accurate?
Yes, if you mean accuarte as in precise step/motion? The only inaccuracy associated with a stepper motor is a noncumulative positioning error which is measured in % of the step angle. Typically, stepper motors are manufactured within a 2-5% step accuracy, even better for some manufacturers.

What is friction with respect to a stepper motor system?
All mechanical systems exhibit some frictional force. The designer of a stepper motor system must be able to predict elements causing friction within the system. These elements may be in the form of bearing drag, sliding friction, system wear, or the viscosity of an oil filled gear box (temperature dependent). A stepper motor must be selected that can overcome any system friction and still provide the necessary torque to accel-erate the inertial load. NOTE: Some friction is desired, since it can reduce settling time and improve performance.

Compared to other stepper motor driver manufacturers, Anaheim Automation offers a lot of microstep driver choices. Why so many models?
Anaheim Automation has one of the broadest lines of stepper motor products in order to give customers as many options as possible, to gachieve the performance they desire in the most cost-effective solution. Typical microstep driver modes range from 'divide-by-8’ to 'divide-by-256' (up to 51,200 steps per revolution for a 1.8 degree motor), which are dependent upon the driver series. Some microstep drivers have a fixed divisor, while the more expensive microstep drivers provide for selectable divisors, up to 256. In general, the larger the microstep divisor provided, the more costly the microstep driver. The higher the current range is, the more expensive the driver. So, to get customers more closely to the exact requirements, we offer a wide variety to choose from. Anaheim Automation also manufactures a series of Integrated Stepper Motors/Drivers, meaning the stepper motor and microstep driver are in one unit. This design approach takes the guesswork out of motor and driver compatibility. For more information, please see the 17MD, 23MD and 34MD series.

Are stepper motor/driver systems durable? Can they be used in a dusty or dirty environment?
Yes, when consideration is given to the overall working environment. The atmosphere in which a stepper motor and driver is used must be conducive to good general practices of electrical/electronic equipment. Do not operate a stepper motor system in the presence of flammable gases, dust, oil, vapor or moisture. For outdoor use, the stepper motor, driver and controller 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 stepper motor, driver and controller in an environment which is free from condensation, dust, electrical noise, vibration and shock, whenever possible. Plan the installation of the stepper motor, driver and/or controller 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 circuitry. Failure to prevent debris from entering the stepper motor system can result in damage and/or shock.

What is the required maintenance for a stepper motor?
Since stepper motors are brushless, they require no maintenance for wear and tear on brushes and commutators. Keeping the environment clean will be helpful.

What is included in the stepper motor and driver packages?
All stepper packages include one each: stepper motor, microstep driver, power supply (enclosed in Driver Pack models), and shielded motor cable (10 feet). Some packages will also include a PCL601 Controller. The MLA10641 drivers are line-powered and do not include a power supply in the MLA packages (not required). Packages are discounted approximately 10% less than if the components were purchased separately. These packages will have one set of support documentation, including the specific package speed/torque curve, hook-up diagram, and driver and controller features. This information is all you should need to select and hook-up your package.

What is the ambient temperature of a stepper motor?
This depends on the class rating for the insulation. Anaheim Automation's standard stepper motors are class B rated. This means an internal temperature of 130°C maximum on the internal windings. With the motors rated current in both windings, the temperature rise is 80°C. So 130°-80° is equal to 50°C maximum ambient temperature.

Is the HMI-ATO-LPS070 able to run a stepper motor?
Yes the HMI-ATO-LPS070 can operate two stepper motors simultaneously. This HMI has such features, speed control, position control, dual axis interpolation and can accept an encoder input for more accurate positioning. The max frequency that the HMI-ATO-LPS070 can output is 100 KHz but can only accurately count a PWM signal up to 400 Hz. If using an encoder one would have to use a less accurate encoder(less lines) or have to slow down there speed for the HMI to properly determine position.

Is the flat on a stepper motor aligned with the step of the motor?
No, the flat on the shaft of our Stepper Motors is not aligned to the step of the motor. For custom options you may contact an Application Engineer for further assistance.
