Abstract

PURPOSE:To make it possible to constantly carry out the single-phase excitation control of the motor to perform an excellent constant-current control by collecting the detected voltages of the current detecting resistors serially connected to respective windings of a pulse motor to a point and deriving the same constantly as voltages per a phase. CONSTITUTION:Switching elements SA through SD are successively turned on by receiving the output pulse from an exciting changeover circuit 3, and respective windings LA through LD are excited. The detected voltages of current detecting resistors RA through RD serially connected to respective windings LA through LD are collected at a point through diodes D1 through D4. Since the detected voltages of respective resistors RA through RD are not affected mutually by diodes D1 through D4, a current per a phase is produced at a point P at the voltage output end in the form of a voltage. A reference voltage and detected voltage are compared with each other in the comparison circuit 2, and by the output of the comparison circuit 2, the current control circuit 1 is controlled, and the constant-current control of an exciting current is carried out.
