    摘 要:以一臺2 極3 kW 的三相異步電機為例,對比分析鑄鋁轉(zhuǎn)子和鑄銅轉(zhuǎn)子對電機性能的影響。利用有限元法建立了電機的二維電磁場模型,對電機轉(zhuǎn)子分別采用鑄銅和鑄鋁時電機的起動性能、堵轉(zhuǎn)特性、磁場分布、導(dǎo)條渦流分布、功率因數(shù)以及效率進(jìn)行了對比分析,得出了轉(zhuǎn)子材料對各個參數(shù)的影響規(guī)律,及當(dāng)電機采用鑄銅轉(zhuǎn)子時所呈現(xiàn)的優(yōu)缺點,為異步電機的優(yōu)化設(shè)計提供參考。

    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
