ABSTRACT:
A rotation stopping apparatus for a motor comprises a frequency signal generating circuit for generating a signal having a frequency according to a rotational speed of a motor, a voltage forming circuit for forming a voltage according to the frequency of the frequency signal from the frequency signal generating circuit, a motor driving circuit for supplying a forward direction current to the motor upon rotation of the motor and supplying a reverse direction current to the motor when the rotation of the motor is stopped to perform a damping operation with respect to the rotation of the motor, a detecting circuit for detecting that a voltage from the voltage forming circuit has become below a predetermined threshold voltage, and an interrupting circuit for interrupting the supply of the reverse direction current to the motor by the motor driving circuit according to the detected result obtained from the detecting circuit.
