Woodward designs and manufactures a broad line of stepper motors for aerospace and defense motion-control applications. Our stepper motors benefit from Woodward’s nearly 50 years of producing servo motors. Early stepper motor designs were primarily “large angle,” but we have expanded our portfolio with several sizes of fine-angle (1.8°) hybrid-type designs which were first popularized in industrial automation.
Performance & Packaging
Woodward stepper motors represent high torque and pulse rates. The size range includes both round and square frames in popular inch-series diameter codes from Size 8 to Size 23 (.75” to 2.3”) and a variety of core lengths.
Applications & Ratings
Common applications for stepper motors include target & navigation servos, cabin pressure, utility actuation, valve, and trim controls. Woodward’s stepper motors can be furnished with a high-temperature construction and insulation system rated up to +220°C.
Accessories
Commonly supplied accessory devices include integral leadscrew output shafts, brakes, and gearheads.
