An Electric Motor is a device that converts electrical energy into mechanical energy, as you have always seen that we supply electrical energy to the motor and we get rotating energy that we are mechanical energy. Power is an ideal staple driver in the motor industries. Most machines are driven by electric motors. The main reason for this is that the efficiency of electric motors is higher than other drivers. Also, his performance is often better than them. The electric motor is also ideal from the point of view of enforcement and control. Driving, or stopping the motor, and changing the speed can be done more easily than other drivers. It can also have a remote control. Electric motors have become so popular due to the ease of control. Let's know more about Electric Motor In Physics.
