Electric Motor:
A device, which converts electric energy into mechanical energy is known as Electric Motor.
Factors on which the speed of Rotation of Motor Depends:
The speed of rotation of motor depends on the following factors.
1. Magnitude of current passing by the motor.
2. Strength of magnetic field.
3. Number of turns in the coil of the motor.
4. Permeability of its armature.
