Because very similar to chi shu rotors very few , the teeth harmonics moment for the second harmonics moment , and two stator mistaken 90e of mutual perspective , the two stator teeth resolved moment worth equal to 13 , 800 conversely , synthetic zero 3 .由于爪極數(shù)等于轉(zhuǎn)子極數(shù),故諧波力矩為2次諧波力矩,而2個(gè)定子相互錯(cuò)位90電角度,所以2個(gè)定子的諧波力矩幅值相等,相位相反,合成為零。
Considering the relations between idle load characteristics and armature winding parameters of the salient pole propulsive synchronous motor ( spsm ) with its structure , stator tooth and magnetic saturation , the analysis of numerical method for the back electromotive force calculation of spsm is given under various exciting current values 摘要針對(duì)凸極式同步推進(jìn)電機(jī)的空載特性及其繞組參數(shù)與電機(jī)結(jié)構(gòu)、定轉(zhuǎn)子齒槽、磁場(chǎng)飽和等緊密相關(guān)的問題,分析了在不同勵(lì)磁電流下同步推進(jìn)電機(jī)相反電勢(shì)的數(shù)值計(jì)算方法,提出了采用電機(jī)磁場(chǎng)能量微動(dòng)法計(jì)算相繞組的參數(shù),并對(duì)一臺(tái)十二相同步推進(jìn)電機(jī)的繞組參數(shù)及其空載特性進(jìn)行了計(jì)算和測(cè)量。
