Abstract
This paper studies the torque characteristics of CDTP controlled BLDCM with various back-EMF waveforms. We propose a CDTP method to suppress torque pulsation due to commutation time and point. It is adopted to control the BLDCM with real back-EMF waveforms through the Hague's method for minimizing torque ripple. Real back-EMF waveforms are produced with a magnetic fringing factor and crest width of back-EMF. The performance and characteristics of the proposed control method are analyzed by simulation and verified through experimental results.
