style="text-indent:25px">隱極式罩極電動機(jī)的定子鐵心與普通單相電動機(jī)的鐵心相同，其定子繞組采用分布繞組，主繞組分布于定子槽內(nèi)，罩極繞組不用短路銅環(huán)，而是用較粗的漆包線繞成分布繞組（串聯(lián)后自行短路）嵌裝在定子槽中（約為總槽數(shù)的2/3），起輔助組的作用。主繞組與罩極繞組在空間相距一定的角度。當(dāng)罩極電動機(jī)的主繞組通電后，罩極繞組也會產(chǎn)生感應(yīng)電流，使定子磁極被罩極繞組罩住部分的磁通與未罩部分向被罩部分的方向旋轉(zhuǎn)。單相串勵電動機(jī)的定子由凸極鐵心和勵磁繞組組成，轉(zhuǎn)子由隱極鐵心、電樞繞組、換向器及轉(zhuǎn)軸等組成。勵磁繞組與電樞繞組之間通過電刷和換向器形成串聯(lián)回路。單相串勵電動機(jī)屬于交、直流兩用電動機(jī)，它既可以使用交流電源工作，也可以使用直流電源工作。直線電機(jī)將電能直接轉(zhuǎn)換成直線運(yùn)動機(jī)械能不需要任何中間轉(zhuǎn)換機(jī)構(gòu)的傳動裝置。邦飛利微型減速箱</p><p

style="text-indent:25px">三相異步電動機(jī)要旋轉(zhuǎn)起來的先決條件是具有一個旋轉(zhuǎn)磁場，三相異步電動機(jī)的定子繞組就是用來產(chǎn)生旋轉(zhuǎn)磁場的。但相電源相與相之間的電壓在相位上是相差120度的，三相異步電動機(jī)定子中的三個繞組在空間方位上也互差120度，這樣，當(dāng)在定子繞組中通入三相電源時，定子繞組就會產(chǎn)生一個旋轉(zhuǎn)磁場。電流每改變一個周期，旋轉(zhuǎn)磁場在空間旋轉(zhuǎn)一周，即旋轉(zhuǎn)磁場的旋轉(zhuǎn)速度與電流的改變是同步的。旋轉(zhuǎn)磁場的轉(zhuǎn)速為：n=60f/P式中f為電源頻率、P是磁場的磁極對數(shù)、n的單位是：每分鐘轉(zhuǎn)數(shù)。根據(jù)此式咱們知道，電動機(jī)的轉(zhuǎn)速與磁極數(shù)和運(yùn)用電源的頻率有關(guān)。磁粉制動器電話</p><p
