Stepper motor drives are devices used to power and control stepper ... Because of the winding configuration, this switching reverses the magnetic fields in the motor. Unipolar motor drive mode is ...

[Neumi] over on Hackaday.IO wanted a simple-to-use way to drive stepper motors ... (which senses the rotating magnetic field on the rear side of the motor assembly – clever!) ...

Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...
