The driving mode of the brushless direct motor can be divided into various driving modes according to different categories, and they each have their own characteristics.
According to the driving waveform: square wave driving, this driving method is convenient to realize, and it is easy to realize the control of the motor without position sensor;
Sinusoidal drive: This drive method can improve the operation effect of the motor and make the output torque uniform, but the implementation process is relatively complicated. At the same time, this method has two methods: SPWM and SVPWM (space vector PWM). The effect of SVPWM is better than that of SPWM.
