摘要:
There is provided a drive control apparatus for a motor having a drive device for controlling current supplied to an armature coil, a control device for controlling the rotation speed of a rotor, and a mode switch device for comparing a rotation speed signal and a predetermined reference voltage and generating a normal rotation mode signal or a reverse rotation mode signal. Furthermore, the drive control device has the drive device, the control device and a signal delay device. The signal delay device delays the supply of a stop signal from the control device by a predetermined time, and a reverse current is supplied to the armature coil during the delay time.
