Abstract
A control system and a control method, used for controlling a motor. The control system includes a central processing module and a drive control module. In a period in which a voltage is not applied to any phase coil of the motor, the drive control module collects voltages of the phase coil, converts the voltages of the coil into digital signals and stores the digital signals. The central processing module reads the digital signals from the drive control module, accumulates the digital signals to obtain an accumulated value, and determines the operating condition of the motor according to a relationship between the accumulated value and a preset threshold, thereby improving the reliability of the motor control.
