根据电磁力定律，载流的转子导体在磁场中受到电磁力作用，形成电磁转矩，驱动转子旋转，当电动机轴上带机械负载时，便向外输出机械能。

异步电机是一种交流电机，其负载时的转速与所接电网的频率之比不是恒定关系。还随着负载的大小发生变化。负载转矩越大，转子的转速越低。异步电机包括感应电机、双馈异步电机和交流换向器电机。感应电机应用广，在不致引起误解或混淆的情况下，一般可称感应电机为异步电机。

普通异步电机的定子绕组接交流电网，转子绕组不需与其他电源连接。因此，它具有结构简单，制造、使用和维护方便，运行可靠以及质量较小， 较低等优点。异步电机有较高的运行效率和较好的工作特性，从空载到满载范围内接近恒速运行，能满足大多数工农业生产机械的传动要求。异步电机还便于派生成各种防护型式，以适应不同环境条件的需要。

According to the law of electromagnetic force, the rotor conductor carrying current is subjected to electromagnetic force in the magnetic field, forming electromagnetic torque, driving the rotor to rotate, and when the motor shaft is loaded with mechanical load, it outputs mechanical energy.

Asynchronous motor is an AC motor, the ratio of the speed of the load to the frequency of the connected grid is not constant. It also varies with the size of the load. The greater the load torque, the lower the rotor speed. Induction motor includes induction motor, doubly-fed induction motor and AC commutator motor. Induction motor is widely used, in the case of not causing misunderstanding or confusion, induction motor can generally be called asynchronous motor.

The stator winding of the general induction motor is connected to the AC power grid, and the rotor winding does not need to be connected to other power sources. Therefore, it has the advantages of simple structure, convenient manufacture, use and maintenance, reliable operation and low quality. Asynchronous motor has higher operating efficiency and better working characteristics, from no-load to full load range close to constant speed operation, can meet the transmission requirements of most industrial and agricultural production machinery. Asynchronous motors can also be easily derived into various types of protection to meet the needs of different environmental conditions.
