單相電機是用了電容的，不論是風扇還是吊扇或者是單相抽水機，這是因為單相電本身是無法構建旋轉磁場帶動電機轉子轉動的，而加上一個電容，則可以利用電容電壓超前電流的原理構建旋轉磁場，有了旋轉磁場，電機才會轉動。 三相電機之所以不用電容，是因為三相電本身就可以構建旋轉磁場了，不需要外加電容。 大功率三相電動機有時候會在旁邊裝設電容，不過那是作為補償電容器，用來補償電機無功功率的。 直流調速非常方便，只要改變電壓就行了，并且基本不影響轉矩。交流調速比較復雜一些，就是眾所周知的變頻器 直流電機具有響應快速、較大的起動轉矩、從零轉速至額定轉速具備可提供額定轉矩的性能，但直流電機的優點也正是它的缺點，因為直流電機要產生額定負載下恒定轉矩的性能，則電樞磁場與轉子磁場須恒維持90°，這就要藉由碳刷及整流子。碳刷及整流子在電機轉動時會產生火花、碳粉因此除了會造成組件損壞之外，使用場合也受到限制。 交流電機沒有碳刷及整流子，免維護、堅固、應用廣，但特性上若要達到相當于直流電機的性能須用復雜控制技術才能達到。交流電動機分為異步電動機和同步電動機兩類。異步電動機按照定子相數的不同分為單相異步電動機、兩相異步電動機和三相異步電動機。三相異步電動機結構簡單，運行可靠，成本低廉等。

Single-phase motor is used in the capacitor, regardless of is the fan or fan or is a single-phase pumps. This is because single-phase electricity itself is unable to construct a rotating magnetic field rotation of the rotor of the motor drive, and a capacitor, the capacitor voltage ahead of current theory to build a rotating magnetic field, rotating magnetic field to rotate with the motor will. Three phase motor is not a capacitor, is because the three-phase power itself can be built in a rotating magnetic field, and do not need additional capacitors. High power three phase motor sometimes will be installed next to the capacitor, but it is used as a compensation capacitor, used to compensate the reactive power of the motor. DC speed control is very convenient, as long as the change of the voltage on the line, and basically does not affect the torque. AC speed regulation are more complex. Is known as the inverter DC motor with response fast, large starting torque, from zero speed to rated speed with rated torque performance, but the advantages of DC motor is its disadvantages, because DC motor to produce the rated load under constant torque performance, armature magnetic field and the magnetic field of the rotor must be constant to maintain 90 degrees, which would be by brush and commutator. Carbon brush and commutator motor rotates in will generate sparks, toner so in addition to cause damage to components, use the occasion is restricted. AC motor without carbon brush and commutator, free maintenance, rugged, wide application, but properties if you want to reached a considerable in the performance of DC motor shall be with complex control technology to achieve. AC motor is divided into two types of asynchronous motor and synchronous motor. According to the difference of the stator phase, the asynchronous motor is divided into the single phase asynchronous motor, the two phase asynchronous motor and the three-phase asynchronous motor. Three phase asynchronous motor has the advantages of simple structure, reliable operation, low cost, etc..
