Option-12, DC Stepper Motor

NEMA 12 Stepper Motors (High Torque)

This NEMA 12 stepper motor actuator can be ordered and factory-fitted to standard AGP motion and manipulation products. It is ideally suited for the 1, 2, and 4 inch linear travel, and/or continuous rotary travel feedthroughs. This is a 'high-torque' stepper motor providing 170 oz-in holding torque with two phases on, and in-series bipolar wiring. It's a standard NEMA 23 frame size (2.24 Inch square mounting flange). With a 200 steps per revolution resolution, this stepper motor can be operated in full, half, and/or micro-stepping configurations... 1.8°, 0.9°, and fractions thereof. AGP does not currently offer motor drivers or controllers, as there's a significant number of solutions on the market
