ABSTRACT:
A pulse motor-driving circuit is disclosed, which circuit includes first and second exciting coils inductively coupled to each other, and first and second switching transistors for alternately exciting the exciting coils, through a D.C. power source. A Zener diode is connected to each of the switching transistors, for suppressing a transient voltage to be impressed on the switching transistors, when the excitations of the exciting coils are changed.
