Difference Between Motor and Generator

Sl. No.

Differentiating Property





An electric motor is a machine that converts electrical energy to mechanical energy.

An electric generator is a machine that converts mechanical energy to electrical energy.`



Electric motor follows Fleming’s left-hand rule.

Electric generator follows Fleming’s right-hand rule.



Motors works on the principle that a current carrying conductor experiences a force when placed in a magnetic field.

Generators work on the principle of electromagnetic induction.


Driving force for shaft

The shaft of an electric motor is driven by a magnetic force which is developed between the armature and field.

The shaft of an electric generator is connected to the rotor which is driven by a mechanical force.


Current Usage

In a motor, current is supplied to the armature winding.

In a generator, current is produced in the armature winding.



Ceiling fans, cars, etc. are all examples of motor.

In power stations, generator is used to generate electricity.
