ABSTRACT:
A pulse motor driving apparatus has a drive circuit for supplying driving pulses to a pulse motor. This drive circuit switches over the exciting winding phases of the pulse motor on a two-phase unit basis, in response to the exciting phase data supplied by a microprocessor in the driving mode, thereby driving the motor by two-phase excitation. The microprocessor specifies only one of the exciting phases in the stopping mode, so that the pulse motor is stopped by single-phase excitation.
