摘要

本文利用COMSOL Multiphysics软件对三相鼠笼式异步电动机进行了时域仿真。将被测电机的转速调整到标称转速,进行了恒转速仿真。给出了定子电流和电机转矩的变化过程,并将其值与目录值和电机测量值进行了比较。由此可见,仿真结果与目录值或实测结果吻合较好。

FEM model of asynchronous motor for analysis of its parameters
This paper presents a time-dependent simulation of three-phase squirrel cage asynchronous motor using COMSOL Multiphysics software. Simulation was made for constant rotational velocity adjusted to the nominal one of the tested motor. The course of stator currents and motor torque is shown and their values are compared to their catalogue ones and values obtained from motor measurements. As seen, the simulation results match the catalogue values or measured results rather well.
