摘　　要：传统空调电机一般采用单相异步电动机,这种单相异步电动机存在效率低、噪音大、功率密度小等缺点,因此,空调电机中性能优越的永磁无刷直流电机将逐渐取代异步电机。利用Ansoft软件建立了空调用永磁无刷直流电机二维瞬态场有限元模型,对铁芯磁场进行分析,并对负载损耗进行计算。软件计算值和实验值的比对误差较小,为空调用永磁无刷直流电机实际产品设计提供了理论依据。Traditional air conditioning motors generally use single-phase asynchronous motors, which have the disadvantages of low efficiency, high noise, and low power density. Therefore, permanent magnet brushless DC motors with superior performance in air conditioning motors will gradually replace asynchronous motors. In this paper, the two-dimensional transient field finite element model of permanent magnet brushless DC motor for air conditioner is established by using Ansoft software. The core magnetic field is analyzed, and the load loss is calculated in this paper. The software calculated value and the experimental value are compared, and the error is small, which provides a theoretical basis for the actual product design of permanent magnet brushless DC motor for air conditioner.
