The rotor current in a 3-phase induction motor is _______ slip.

  • The rotor current in a 3-phase induction motor is Directly proportional to slip.
  • Slip is defined as the difference between synchronous speed and rotor speed divided by synchronous speed.
  • It is the percentage difference between the speed of the rotating magnetic field produced by the stator and the speed of the rotor.
  • When an AC voltage is applied to the stator winding of an induction motor, a rotating magnetic field is created.
  • This magnetic field induces a voltage in the rotor windings, which in turn, creates a current in the rotor conductors.
  • The interaction between the stator magnetic field and the rotor current produces a torque, which causes the rotor to rotate.
