The universal motor is a type of electric motor that can operate on either AC or DC power and uses an electromagnet as its stator to create its magnetic field. The voltage drop in the variable resistance reduces the applied voltage to the armature, and as a result, the speed of the motor is reduced. It allows a full terminal voltage across the field winding while both of windings have the same amount of voltage across it. The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors.The armature can be on either the rotor (rotating Working of DC Motor. The rotor has a DC armature, with commutator segments and brushes. (Draw the circuit diagram) Now as the motor continues to rotate, the back emf starts being generated, and gradually the current decreases as the motor picks up speed.
