The Technology Study of BLDCM Speeding on Different PWM Mode

Article Preview

Abstract:

For the PWM mode of BLDCM speeding, the paper presents a detailed analysis on five PWM modulations, and presents the six switches’ working waveforms, the motor armature voltage and current waveforms on different PWM modulations. The simulation results show that HPWM-LON mode can significantly reduce motor armature voltage harmonic component, and can create good condition for the motor running. So we choose the right speeding way of BLDCM which has very important practical significance for industrial and agricultural production.
