Abstract

PURPOSE:To drive the motor smoothly under no vibration produced by the variation of driving speed by controlling a current in the motor coil according to the driving speed of pulse motor. CONSTITUTION:The output transistor is turned on or off by the buffers 101 to 103 when a pulse signal produced in the pulse-motor control pulse generator 80 is ''0'' or ''1'' respectively. Also the pulse generator 80 contains the coil conduction current control pulse generator, a pulse of which is fed to the DA converter 81 and amplified in the resistance 82 and transistor 83, an analog signal voltage develops at the point y. This voltage, resistance 111, transistor 131 and resistance 141 form a single phase constant current circuit, and determine a current value corresponding to the driving speed. By this way, the motor current can be made less than the setting value to eliminate vibration of the motor.
