【摘要】：提出一種電動汽車用雙層永磁體內(nèi)置式永磁同步電機(interior permanent magnet synchronous machine,IPMSM),分析其基本電磁關(guān)系,進行優(yōu)化分析。采用有限元分析軟件建立電機結(jié)構(gòu)模型,分析單邊氣隙長度不同時氣隙磁密及諧波畸變率變化規(guī)律;研究了不同定子槽口寬度下電機齒槽轉(zhuǎn)矩的變化趨勢;通過改變第二層永磁體兩側(cè)隔磁橋間距Rib及第一層永磁體中間隔磁橋與轉(zhuǎn)軸距離O2,獲得電機輸出轉(zhuǎn)矩與轉(zhuǎn)矩紋波的變化規(guī)律;分析雙層永磁體尺寸變化時的電機效率,得到最優(yōu)永磁體尺寸參數(shù)。樣機試驗表明:實測值與仿真值基本吻合,驗證了樣機設(shè)計的合理性。
[Abstract]:A double layer permanent magnet built-in permanent magnet synchronous motor (interior permanent magnet synchronous machine,IPMSM) for electric vehicles is proposed. The basic electromagnetic relationship is analyzed and optimized. The finite element analysis software is used to set up the motor structure model, to analyze the variation law of magnetic density and harmonic distortion rate of air gap with different air gap length, and to study the change trend of the torque of tooth slot of motor under different stator slot width. The variation of motor output torque and torque ripple is obtained by changing the Rib distance between the two sides of the permanent magnet and the distance between the bridge and the rotating axis in the first layer permanent magnet, and the motor efficiency is analyzed when the size of the double layer permanent magnet changes. The optimal parameters of permanent magnet size are obtained. The experimental results show that the measured values are in good agreement with the simulation values, and the rationality of the prototype design is verified.
