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. In a motor, current is supplied to the armature winding, whereas in a generator, current is produced in the armature winding. The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the motor is an electric device which converts electrical energy into mechanical energy, the generator is vice versa of that motor.
