Motor Driving Device

摘要

The present invention provides a motor driving device without an additional signal line for identifying whether a motor rotates stably. The motor driving device (21) includes a control circuit (100) for receiving an acceleration signal (SU) and a deceleration signal (SD), and generating a driver control signal (S10); a driving circuit (200) for generating a motor driving signal (S3) according to the driver control signal (S10); and a phase-locked identifying circuit (500) for monitoring an input mode of the acceleration signal (SU) and the deceleration signal (SD), and identifying whether the motor rotation speed is stable at the desired target rotation speed.
