Anaheim Automation's Permanent Magnet (PM) Threaded Shaft Linear Actuators are the perfect choice for cost-effective linear motion. This stepper motor internally converts rotary motion to linear motion via a rotating nut and a leadscrew, thus eliminating the need for any other rotary-to-linear conversions such as rack and pinions, belts and pulleys, or external ball screws. The stepper motor comes in five sizes, a standard 4-lead configuration, and motion designs can be simplified, product life enhanced, and production costs lowered. These Permanent Magnet (PM) Threaded Shaft Linear Actuators are customizable, so achieving the winding you need to perfectly match your voltage, current, and maximum operating speed is easy. Special screw modifications, cables and connectors are also available upon request.
