    摘 要:以一台2 极3 kW 的三相异步电机为例,对比分析铸铝转子和铸铜转子对电机性能的影响。利用有限元法建立了电机的二维电磁场模型,对电机转子分别采用铸铜和铸铝时电机的起动性能、堵转特性、磁场分布、导条涡流分布、功率因数以及效率进行了对比分析,得出了转子材料对各个参数的影响规律,及当电机采用铸铜转子时所呈现的优缺点,为异步电机的优化设计提供参考。

    Abstract: Taking a 2-pole 3 kW three-phase asynchronous motor as an example, this paper contrastively analyzed the influence of cast aluminum rotor and cast copper rotor on the motor performance. This paper used the finite element method to establish the two-dimension electromagnetic field model to carry out contrastive analysis of starting performance, locked-rotor characteristic, magnetic field distribution, conducting bar eddy distribution, power factor and efficiency when the cast aluminum rotor and cast copper rotor were individually applied in the motor. The influence rule to each parameter from rotor material was obtained, as well as the advantages and disadvantages appeared when the motor adopted cast copper rotor, so as to provide references for the optimization design.
    Key words: cast copper rotor; cast aluminum rotor; asynchronous motor; locked-rotor torque; overload ability; electromagnetic field
