characteristic:

The application of DC brushless motor controller in fan drive includes three application schemes: separation device, Sanken IPM, and Mitsubishi IPM.

This scheme adopts dual closed-loop control (speed and current), space vector pulse width modulation (SVPWM), and field oriented control (FOC) technologies, which greatly improve system efficiency, extremely low torque ripple, and operating noise. It is an excellent way for home appliance manufacturers and motor manufacturers to solve power consumption control and alleviate price pressure.
