Title:
CONTROL SYSTEM FOR MOTOR
Document Type and Number:
Japanese Patent JPS6059987
Kind Code:
A
Abstract:
PURPOSE:To reduce the influence of variation in one step of a pulse width by switching a drive power source at between accelerating/decelerating time and constant speed time by a CPU when driving a motor by the internal calculation of the CPU by a pulse of an encoder. CONSTITUTION:The rotating direction and speed of a motor are detected by the pulse of an encoder provided in a motor 5, a control amount is outputted to a counter 3 by the internal calculation of a CPU, a transistor controlled by a rotary command during a pulse width is turned ON to control the supply power to the motor 5. A signal is fed from the CPU1 to a drive power source 2, which is switched to high voltage at the accelerating/decelerating time when the work amount is large and to low voltage at the constant speed time when the work amount is less. Accordingly, the influence of the variation in one step can be reduced by increasing the width of the pulse at the constant speed time, thereby reducing the irregular rotation.
