Research on Electromagnetic Field and Stress Field of Permanent Magnet Motor with Time Stepping Finite Element Calculation
摘要
Abstract
A 22 kW line-start permanent Magnet ( PM ) motor was illustrated to analyze the distribution of electromagnetic field and mechanical stress field with the time stepping finite-element method. The mechanical stress and strain were studied under several common operating conditions. The strains of the motor under extreme conditions were obtained. The calculation results showed that, the PM motor had a damage risk of serious mechanical deformation under the starting with load and overload. The analysis method had an important reference value for the motor design and security operation.关键词
