1.8° 86H SERVO Stepper Motor

1.8° 86H SERVO Stepper Motor Product Introduction Our 1.8° 86mm 2-phase hybrid stepper motor is a closed-loop servo stepper model, recognized globally as standard NEMA 34 hybrid stepper motor and universal 86mm frame stepping motor. It functions as a powerful high torque industrial stepper motor and robust heavy duty 2-phase bipolar stepper motor. Built with NEMA34 standard 86×86mm square mounting frame, body lengths cover 105mm to 175mm, holding torque ranges from 4.5 N.m up to peak 12 N.m, with standard 4-lead bipolar wiring and built-in encoder for closed-loop servo control. This design eliminates step loss, boosts dynamic response speed and positioning accuracy, widely adopted for medium and heavy-duty industrial automation production lines worldwide.
