摘　　要：利用有限元仿真软件Ansoft对二维电机模型进行分析,研究计算了磁钢偏心距、极弧系数及气隙长度对交流永磁伺服电动机气隙磁密的影响。通过合理设计各参数,使气隙磁密更接近正弦,并研制了样机,样机测试的效率为93%,满足了高效节能电机的技术要求。The two-dimensional motor model was analyzed by means of the finite element simulation software.The influence on the air-gap magnetic density of AC PM Servo motors by the magnetic steel eccentricity,pole embrace and air-gap length was studied and calculated.The reasonable design of the various parameters made it possible that the air-gap magnetic density was very closed to the Sine.The prototype was made with a tested efficiency of 93% to meet with technical requirement of a high-efficiency and energy-saving motor.
