Title:
MOTOR PWM DRIVE CIRCUIT
Document Type and Number:
Japanese Patent JP3806577
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a motor PWM drive circuit which does not need two types of input signals, i.e., a speed control input signal and an S/S input signal, which a conventional circuit needs.
SOLUTION: A start/stop signal is generated from a PWM pulse signal obtained by inputting a speed control input signal to a PWM pulse generating circuit. With this constitution, PWM drive of a motor can be practiced by the speed control input signal only.
