GEOLOGY

Detailed explanation-1: -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-2: -In a generator, the commutator picks up the current generated in the windings, reversing the direction of current with each half turn, converts AC current into DC current.

Detailed explanation-3: -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-4: -How to Reverse Your DC Motor. Your DC motor can be configured to turn in either direction by simply inverting the polarity of the applied voltage. The change in the flow of current switches the direction of the spinning force, causing the motor’s shaft to begin turning in the opposite direction.
