Detailed explanation-1: -The commutator reverses the current flow within a winding when the shaft turns. Once the shaft completes a half-turn, the windings are connected so that current supplies through it in the reverse of the first direction. In a DC motor, the magnetic field uses a rotating force or a torque over to the winding to rotate.

Detailed explanation-2: -In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation.

Detailed explanation-3: -A motor contains a kind of switch called a Commutator, which reverses the current every half rotation.

Detailed explanation-4: -Then, the only way to “reverse” the circuit is applying the ubiquitous negative feedback. Only systems with negative feedback have the unique property to reverse the cause and effect relations between the input and output quantities of the objects.

Detailed explanation-5: -The current to the coil be reversed twice during each rotation so that the coil rotating continuously in the same direction. Was this answer helpful?
