核主泵驱动电动机屏蔽套涡流损耗混合算法研究
Research on Hybrid Algorithm of Can Losses in Double Canned Induction Motor for Nuclear Pump
摘要
Abstract
The calculation of stator and rotor can losses in large double canned induction motor for nuclear pump was very complicated. In view of this problem, a hybrid algorithm was proposed. The 2-D finite element method and analytic method were combined in the proposed algorithm and the contradiction between the calculation accuracy and calculation speed in the calculation of can losses was solved. In this paper, based on the 2-D numerical analysis of magnetic field, the 2-D analytic models of stator and rotor can losses were derived by combing Maxwell′s equations. Taking a megawatt double canned induction motor for nuclear pump as an example, the stator and rotor can losses were calculated and analyzed in detail, by comparing with the result of transient magnetic finite element method, the correctness of the hybrid algorithm is verified.关键词
