MOTOR DRIVING CONTROL CIRCUIT

摘要

The present invention provides a motor driving circuit. The motor driving circuit according to the present invention comprises: a rotatable motor; an FG signal detecting unit for detecting a frequency generation (FG) signal according to rotation of the motor; a control unit for filtering noise from the frequency generation signal and generating a speed error signal from the frequency generation signal from which noise is filtered; and a driving control circuit for controlling driving of the motor based on the speed error signal, thereby controlling rotation speed based on the frequency generation signal from the motor.
