電機(俗稱"馬達")是指依據(jù)電磁感應(yīng)定律實現(xiàn)電能轉(zhuǎn)換或傳遞得一種電磁裝置。它得主要作用是產(chǎn)生驅(qū)動轉(zhuǎn)矩，作為用電器或各種機械得動力源。
A motor (commonly known as a "motor") refers to an electromagnetic device that realizes the conversion or transmission of electrical energy according to the law of electromagnetic induction. Its main role is to generate drive torque as a power source for electrical appliances or various machinery.

The electric motor consists mainly of an electromagnet winding or distributed stator winding used to generate a magnetic field and a rotating armature or rotor and other accessories. Under the action of the rotating magnetic field of the stator winding, it has a current passing through the armature cage aluminum frame and is rotated by the magnetic field.

1、直流電動機
直流電機是將直流電能轉(zhuǎn)換成機械能(直流電動機)或?qū)C械能轉(zhuǎn)換成直流電能(直流發(fā)電機)得旋轉(zhuǎn)電機。它是能實現(xiàn)直流電能和機械能互相轉(zhuǎn)換得電機。當(dāng)它作電動機運行時是直流電動機，將電能轉(zhuǎn)換為機械能；作發(fā)電機運行時是直流發(fā)電機，將機械能轉(zhuǎn)換為電能。
A DC motor is a rotating motor that converts DC electrical energy into mechanical energy (DC motor) or converts mechanical energy into DC power (DC generator). It is a motor that can convert DC power and mechanical energy to each other. When it is used as a motor, it is a DC motor, which converts electrical energy into mechanical energy; when it is a generator, it is a DC generator that converts mechanical energy into electrical energy.

The physical model of the DC motor in the figure above has a magnet in the fixed part, which is called the main magnetic pole here; the fixed part also has an electric brush. The rotating part has a ring core and a winding wound around the ring core. (The two small circles are set to facilitate the direction of the conductor potential or current at that position.)

異步電動機又稱感應(yīng)電動機，是由氣隙旋轉(zhuǎn)磁場與轉(zhuǎn)子繞組感應(yīng)電流相互作用產(chǎn)生得電磁轉(zhuǎn)矩，從而實現(xiàn)機電能量轉(zhuǎn)換為機械能量得一種交流電機。
Induction motor, also known as induction motor, is an AC motor that generates electromagnetic torque by interacting with the induction current of the air gap rotating magnetic field and the rotor winding, thereby realizing the conversion of electromechanical energy into mechanical energy.

永磁電機是利用永磁體提供磁場得電動機。電動機做功，需要2個條件，一個是存在磁場，另外一個是磁場中有運動得電流存在。
A permanent magnet motor is an electric motor that uses a permanent magnet to provide a magnetic field. To do the work of the motor, it takes 2 conditions, one is the presence of a magnetic field, and the other is the presence of a current in the magnetic field.
