BLDC MOTOR FOR THE ELECTRIC CAR AND CONTROLLING APPARATUS FOR THE BLDC MOTOR, AND CONTROLLING METHOD FOR THE SAME

摘要

PURPOSE: A BLDC motor for an electric vehicle, a control device thereof, and a controlling method thereof are provided to improve stability by performing an emergency operation. CONSTITUTION: A main board(300) outputs a driving signal of a switching unit(500). A control unit(400) inputs a switching signal to the switching unit and receives a command signal and a sensor signal. The switching unit drives a motor by a switching operation. A sensor generates the sensor signal by sensing the driving of the motor.
