SM-Series Slotless Stator Brushless Servo Motors

Brand: Parker Hannifin

Available in NEMA 16 and 23 frame sizes, SM motors incorporate a slotless stator and 4-pole design allowing it to operate smoothly with zero detent torque and be driven at very high speeds. Parker can provide custom modifications to all SM motors.

Parker’s SM series servo motor incorporates a slotless design to eliminate all detent (cogging) torque in the motor.

This motor provides superior performance in applications requiring smooth, low speed operation and is also capable of high speed operation with rated speeds of over 7,000 rpm.
