NEMA 23 57HC 1.2° 3-Phase Hybrid Stepper Motor

Product Display

STEPPERONLINE  provides different kinds of hybrid 3 phase stepper motor. Compared to 2-phase motors, 3 phase stepper motor can provide more torque and it has a better performance in over-loading. That is to say, when the load gains, no like other steppers, 3 phase stepper motor will not stall easily. And it has a good dynamic property at the same time.As 3-phase motor has a smaller step angle than 2-phase motors, it moves more smoothly. Under the condition of having the same rotor teeth, 3-phase motors has less vibration and higher precision than 2-phase motors.

This is the biggest cnc stepper motor we have, it with size 130*130mm. It has 4 wires, each phase draws 6A, allowing for a huge torque up to 37Nm (5239oz.in).
