Abstract

PURPOSE: To prevent a pulse motor from generation of heat by detecting the issue of a pulse signal and controlling the field current of the pulse motor for reducing the electric consumption.
CONSTITUTION: A current control circuit 7 to control the field current of a pulse motor 1 is constructed to detect the pulse signal input into the pulse motor 1 and issue a control signal of the second driving circuit 8 for controlling the supply of the field current to the pulse motor 1 from an electric source 6. Consequently, the pulse motor 1 can be supplied with a fixed value of the field current only when a pulse signal for rotational driving is input; otherwise the field current can be reduced to zero or by a minute value for reducing the current consumption.
