The direction of rotation of the 3-Φ induction motor is clockwise when it is supplied with the 3-Φ sinusoidal voltage having a phase sequence of A-B-C. For counterclockwise rotation, the phase sequence of the power supply should be

  • The direction of rotation of the 3-Φ induction motor is clockwise when it is supplied with the 3-Φ sinusoidal voltage having a phase sequence of A-B-C. For counterclockwise rotation, the phase sequence of the power supply should be A-C-B.
  • The direction of rotation of a 3-Φ induction motor depends on the phase sequence of the applied voltages.
  • The phase sequence refers to the order in which the voltages in a 3-Φ system reach their maximum values.
  • In a 3-Φ system with a phase sequence of A-B-C, the direction of rotation of the motor is clockwise.
  • If the phase sequence is changed to A-C-B, the direction of rotation of the motor will be counterclockwise.
