Re: Rotating unpowered stepper motor, good or bad

Thx for the reply.

Hi,
A couple of things to keep in mind.
1. As the steppers are not wired, if two of the wires that are part of the same coil in the stepper touch each other, it will be difficult to rotate the motor. It effectively applies a brake on the motor
2. When you do wire them up and connect them to your controller, turning the motor by hand will generate energy and "push" it into the controller. Some controllers are sensitive to this and it can harm the stepper driver in the controller. That said many good quality drivers such as Geckodrives have protection against this.
Cheers,
Peter
