摘要

本文提出了一种新型复合式笼形转子异步电动机，其转子棒由上部为合金(电、磁导体)，下部为铸铝组成。采用有限元法对IMCCR的电磁场和热场进行了耦合分析。首先计算了锁转子电动机运行时的电磁场和冲击电流，并通过热分析研究了电动机的瞬态传热过程。因此，研究了运行状态对电机性能的影响，特别是对绕组绝缘的影响。所得结果与实验数据进行了比较。

The short time transient thermal analysis of IMCCR in two special operating state

A new kind of induction motor with compound cage rotor (IMCCR) is proposed in this paper, in which rotor bars are composed of upper parts made of alloy (conductor for electric and magnetic) and lower parts made of cast aluminum. By using FEM, the electromagnetic and thermal fields of IMCCR are analyzed with coupling. The electromagnetic fields of motor operating with locked rotor and striking current are calculated first, and the transient heat transfer processes in motor are studied through thermal analysis. Thus, effects of operating state on motor performance are studied, especially for the windings insulation. The obtained results are compared with the experimental data.
