Abstract: RMxprt is a design concept of simulation and calculation of various motor models based on motor equivalent circuit and magnetic circuit with the advantages of simple and fast modeling and easy parameter adjustment.The application of RMxprt module in the 2D field of three-phase asynchronous motor is discussed with a three-phase asynchronous motor as example to achieve better simulation of three-phase asynchronous motor and solution of 2D and 3D finite elements.The calculation results of experiment agree well with the FEM results with an error only of 0.366 2%,fully meeting the needs of engineering.

Key words: Maxwell;2D three-phase asynchronous motor;electromagnetic field analysis
