An electromagnetic field (emf) is induced in a current-carrying conductor when it is put in a changing magnetic field according to Faradays law of electromagnetic induction and Flemings right-hand rule states that as the conductors direction of motion alters, so does the direction of the induced current. When motor terminals are connected to DC mains, field gets excited and alternate N-pole and S-pole is The generator is usually coupled to a prime A dc electric generator is simply a machine that converts mechanical energy into dc electrical energy. There are many differences between AC and DC motors. A DC motor is an electrical machine which converts electrical energy into mechanical energy.
