57RB series two four phase hybrid stepper motorDetailed product description：

57RB series 24 phase hybrid stepper motor

The material cost of the 57RB series stepper motor is the same as that of the 57HB series stepper motor, but the torque of the 57HB series stepper motor is larger. Therefore, since the implementation of the 57HB stepper motor in 2006, the 57RB series stepper motor has gradually been phased out. Currently, users of the 57RB series stepper motor mainly replace parts on old equipment. Please confirm the following important parameters when purchasing:

1. Step angle;
2. Current;
3. Body length;
4. Shaft diameter;
5. Output shaft length;
6. Output method (optical axis, single flat, double flat, keyway);
7. Outgoing method.
