Motor control circuit and motor drive system using the same |
摘要 |
A motor control circuit includes a driver which amplifies a drive signal and outputs a drive current to a coil of a motor ; a detection circuit which detects a drive waveform of the drive current and outputs a detection pulse representing a rotating condition of the motor as a detection signal ; and a drive signal generating circuit which generates in response to the detection pulse a trapezoidal wave having a linear inclination at front and rear parts thereof as the drive signal.
