Feldy-Stephens - 3-2 STEPPING MOTOR CONTROL CIRCUIT ABSTRACT OF THE DISCLOSURE A stepping motor is described having two operative modes, the first mode being a normal rotary mode and the second a stationary mode. during rotary operation, the induced energy created by interruption of the current flow through the energized phase winding is dissipated quickly by a zener diode connected across the winding. In the stationary mode, a pulsed current is fed to one of the phase windings of the motor to assure stationary position- ing of the rotor. During stationary operation, the zener diode is shunted with a second conventional diode provid- ing a low impedance path to the current induced in the phase winding upon de-energization. This low impedance path greatly reduces the energy dissipated during the off condition of the pulsed current thereby greatly reducing motor power requirements during stationary operation. -1-
