  • An alternator has a phase sequence of RYB for its phase voltage. In case the direction of rotation of alternator is reversed, the phase sequence will become RBY.
  • When an alternator is rotating in one direction, the phase sequence of its output voltages is determined by the physical orientation of its windings.
  • In an alternator with a phase sequence of RYB, the phase voltages will reach their peak positive values in the order of phase R first, followed by phase Y, and then phase B.
  • However, if the direction of rotation of the alternator is reversed, the physical orientation of the windings will also be reversed.
  • As a result, the phase voltages will reach their peak positive values in the order of phase R first, followed by phase B, and then phase Y.
  • This means that the phase sequence of the alternator will become RBY when its direction of rotation is reversed.
