在電機(jī)仿真中,鐵耗的精確計(jì)算十分重要,Maxwell瞬態(tài)場(chǎng)求解器下默認(rèn)不打開(kāi)鐵耗的計(jì)算,需要手動(dòng)勾選;另外,基于標(biāo)準(zhǔn)斯坦梅茲公式(steinmetz method)計(jì)算的鐵耗并未考慮對(duì)轉(zhuǎn)矩等場(chǎng)數(shù)據(jù)的影響,而Maxwell中可以單獨(dú)考慮,操作如下:

點(diǎn)擊菜單 Maxwell 2D/3D>Excitations>Set Core Loss

在彈出的General下,選擇需要計(jì)算的stator / Rotor

在彈出的Set Core Loss下,Advanced下,勾選 □Consider core loss effect on field

1.勾選□Consider core loss effect on field前后,輸出轉(zhuǎn)矩值對(duì)比,勾選后輸出轉(zhuǎn)矩值降低

2.若只考慮Set up coreloss,但是不勾選Consider core loss effect on field,二者波形相重合
