Problems solved by technology
For example, in the current electric car control, the frequency usually used is 10K. When the car is running at high speed, the switching times of the motor are the same as the switching speed at low speed. This will easily cause the power device to switch frequently, resulting in damage to the device.
[0005] Therefore, in view of this situation, it is urgent to design and produce a synchronous motor control method to solve the problem that the drive module is prone to failure, the motor is prone to vibration, and the power device is damaged in the prior art.
