ABSTRACT:
The disclosed circuit is for controlling step motors of the type which have access only to a common winding neutral point or to partial neutral points. A switching transistor switches a low-loss circuit into the motor drive circuit for free running of the motor. A common circuit common to all the windings is switched in for rapid switching off of the current in the windings and for recovery of the energy stored in the inductors of the circuits.
