基于磁固耦合法对比经典与新型双励磁开关磁阻电机电磁振动特性分析
Based on Magnetic Solid Coupling Method Compared to Classical and New Double Excitation Electromagnetic Vibration Characteristic Analysis of Switched Reluctance Motor
摘要
Abstract
Through the comparative study on the electromagnetic and mechanical finite element method ( fem) of a new type of excitation motor electromagnetic vibration characteristics. In this new type of motor stator side, placed a dc excitation winding were calculated and compared based on this model and the traditional electromagnetic characteristics of switch reluctance motor. Using MATLAB software to the air gap flux density and radial electromagnetic force in the harmonic analysis. Second modal analysis was carried out on the stator, it was concluded that the natural frequency and modal vibration mode, finally through the electromagnetic-structure coupling method to calculate the electromagnetic vibration response of the stator, to analyze its vibration characteristics. Studies have shown that this new type of double excitation motor had obvious effect to reduce electromagnetic vibration.关键词
