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
