摘　　要：为配套中央空调外部风机,设计了一款910 r/min、9槽10极三相无刷直流电动机,从电动机结构、永磁材料、磁体结构等方面分析了外转子永磁无刷直流电机的设计要求。利用Ansys/Maxwell建立了该电动机的二维有限元仿真模型,并对性能进行了仿真,最后进行了试制、调试及试验。结果表明:外转子永磁无刷直流电动机驱动风机,性能良好,验证了软件仿真的准确性。A three phase brushless DC motor of 910 r/ min,10 poles,9 slots,was designed to form a complete set ofcentral air conditioning external air-pumps. The motor structure,material,magnet structure was analyzed. A 2D finite ele-ment analysis model was established with Maxwell of Ansys. The motor performances were simulated. The design scheme wastested and the sample was manufactured. The external rotor BLDCM was used to drive the air-pumps. The measured datashow that the motor is more advantage for industrialization,which confirmed the accuracy of the 2D finite element model.
