AC Generator | DC Motor |
1) A generator is a device which converts the mechanical energy into the electrical energy. | 1) A DC motor is a device which converts electrical energy into the mechanical energy. |
2) A generator works on the principle of electromagnetic induction. | 2) A DC motor works on the principle of force acting on a current carrying conductor placed in a magnetic field. |
3) In a generator, the mechanical energy is used in rotating the armature coil in a magnetic field so as to produce electricity | 3) In a DC motor electrical energy is provided by the DC source to flow current in the armature coil placed in a magnetic field due to which coil rotates. |
4) A generator makes use of two separate coaxial slip rings. | 4) A DC motor makes use of two parts of a slip ring (i.e., split rings) which acts as commutator. |
