Abstract
In this paper the novel operation method of concentration winding BLDC motor of air conditioner compressor to improve efficiency is proposed.. Because it demands generally the need of more confidential sensorless operation, it Is hard to apply to three phases - three excited operation by reason of intricate calculations. In order to improve the defects of 120 degrees electrical conduction method, a novel PW Pattern is proposed. Established three phases - two excited system on real load air conditioner is used in experiment.
