Working Principle of DC Motor | Robu

 · A DC motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of the DC motor is that whenever a current carrying conductor places in the magnetic field, it experiences a mechanical force. Fleming''s left-hand rule and its magnitude decide the direction of this force.
