摘要
本文用有限元方法对CTD调速电动机的涡流场进行了分析和计算。通过涡流损耗方法对CTD调速电动机的杯转子电阻进行了较准确地计算,为CTD调速电动机的研制设计提供了依据。最后通过试验电机杯转子电阻的测试和计算,得到了令人满意的结果。
In this paper the eddy field of a CTD variable speed motor is analysed and calculated by the finite element method. The cup-rotor resistence of CTD variable speed motor is calculated comparaturely accurately by the eddy current loss method, which provides a basis for the development and the design of CTD variable speed motor. Thus, the calculation and the measurement of the cup-rotor resistance of a test CTD variable speed motor are proceeded with a satisfactory result.
