Abstract

Permanent magnet brushless motor used for deep-sea human occupied vehicle´s (HUV´s) propeller was studied in this paper. Based on analyzing the influences of waveform of phase current on flux density in air gap, rotor eddy-current losses were determined in BLAC and BLDC modes. This paper proposed that rotor loss is the minimum in BLAC mode. In BLDC mode, with optimal commutation advance angle (20Â°), rotor loss is the lowest. Finally the temperature distribution of the motor was gained considering the rotor eddy-current loss.
