CONSTRUCTION & WORKING OF DC MACHINE .

DC Generator converts the Mechanical Energy into Electrical Energy (in DC). Its working principle is Faraday's Law of Electromagnetic Induction which states that, whenever a conductor is placed in a varying magnetic field (or conductor is moved in magnetic field), then an emf is induced in it.If the circuit of the conductor is closed, then current also starts flowing through it.

DC motor - Wikipedia

A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.
