Brushless DC motor is commonly used in our daily life, the controller is a key part of the motor, in order to maintain a smooth operation, then how does it manipulate the rotation?
1, can use electricity to adjust, there is a difference between the electric modulation inverter, the work of the inverter is fixed after it becomes the electric modulation, so the electric modulation can be used, but the rotation speed bearing is all fixed, similar to the open loop control method, can not take heavy load.If you have to flip it, you can also switch the dynamic lines of V and W.
2, the inverter power supply additional control circuit to operate, the DC power supply inverter frequency and amplitude sinusoidal waveform, the inverter output is waveform, because its self-induction electromotive force is square, this kind of control mode is the servo motor driver.This type of manipulation is flexible, does not lose step due to overloading, and can integrate many maintenance functions.
