istics of the rotor magnetic field distribution and the space division. The data collection is de-Р signed based on the location of the measurement points. Double stimulation continuous mass classification method has been adopt-Р ed to compare the visualization effects of the rotor external magnetic field under the two space division strategies. Experimental re-Р sults proved the effectiveness of the method proposed in this paper.Р Р Key words PMSM rotor magnetization magnetic field detection data visualization DSCQSРР [编辑 周廷美]
