Product introduction

The ultra-high-speed motor controller product specially developed for the air compressor motor of the fuel cell system hashigh control accuracy, small

harmonic current, fast response speed and perfect protection function. 

Features

Conversion efficiency up to 98%, saving hydrogen consumption;

Has a wide DC voltage range (250~750VDC);

Reliable and stable vector control algorithm without speed/position sensor;

High control precision, fast response speed and perfect protection function;

The output frequency can reach 0~3000Hz, and the maximum speed of the motor can reach 180000rpm;

Small output current harmonics effectively reduce motor heating;

The output dV/dt is small, which effectively reduces the motor shaft current and protects the motor insulation life.
