    I purchased the 3-pack of the smaller steppers for my current ender 3 pro project. For my applications, they work perfectly. It's a great deal for quality motors, and I'm going to purchase another 10 packs.

    These are great motors and they are very strong. They are operating quietly, and also need them to release their hold every time a move is complete.

Product Description

57BYGN400A Customization 1.8 Degree 56mm High Torque Nema 23 Step Motor



1. Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.

2. The motors response to digital input pulses provides open-loop control, making the motor simpler and less

costly to control.

3. It is possible to achieve very low speed synchronous rotation with a load that is directly coupled to the shaft.

4. A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input
