Electric Motor / Coolant Pump / Vacuum Pump Motor( 电机 / 水泵 / 马达 / 真空泵 )

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

电动机(Motor)是把电能转换成机械能的一种设备。它是利用通电线圈(也就是定子绕组)产生旋转磁场并作用于转子(如鼠笼式闭合铝框)形成磁电动力旋转扭矩。电动机按使用电源不同分为直流电动机交流电动机,电力系统中的电动机大部分是交流电机,可以是同步电机或者是异步电机(电机定子磁场转速与转子旋转转速不保持同步速)。电动机主要由定子与转子组成,通电导线在磁场中受力运动的方向跟电流方向和磁感线(磁场方向)方向有关。电动机工作原理是磁场对电流受力的作用,使电动机转动。
