Stepper Servo Motors

CUI Devices’ stepper servo motors pair compact NEMA 8, 11, 14, 17, and 23 stepper motors with our AMT incremental encodersAMT incremental encoders for a reliable motor and motion control feedback solution. Our stepper servo motors offer holding torques up to 270 oz-in (1.90 N-m) and resolutions up to 4096 PPR. The encoders are fully programmable and in combination with the motor, provide closed-loop feedback when paired with a controller for a complete servo system.
