What is the relative speed between stator field and rotor field?

The relative speed between the rotor field and stator is synchronous speed and it is 1500 rpm.

What will happen if relative speed between the rotating flux of stator and rotor of the induction motor is zero?

What will happen if the relation speed between the rotating flux of stator and rotor of the induction motor is zero? By varying the rotor resistance in the slip ring induction motor the maximum torque can be achieved at any desired slip or speed of.

What is the relation between rotor and stator mmf?

What is the relation between rotor mmf and stator mmf? Explanation: First the stator mmf is calculated. Then it is multiplied by 0.85 to obtain the rotor mmf.

What is relative speed of stator flux with respect to rotor flux?

The relative speed between the rotor field and stator field is zero. The relative speed between stator filed and stator is synchronous speed.

Which motor the speed can be controlled from rotor side?

Cascade Operation of Induction Motor: In speed control by cascading of two induction motors, the rotors of the two motors are mechanically coupled. One motor is called Main Motor and the second motor is called auxiliary motor.

What is the correct relationship between rotor MMF and stator MMF in synchronous motor?

Rotor mmf wave. Stator MMF wave rotates at synchronous speed whereas stator is fixed. Rotor winding rotates at a speed less than synchronous speed and depends on the slip. Both rotor and stator MMF waves rotate in the air gap in the same direction at synchronous speed when balanced 3 – φ supply is given.

What is the corresponding speed of rotor with respect to stator?

(i) Frequency of stator current = 50 Hz (ii) Speed of rotor magnetic field w.r.t. rotor = (N. -N) = 1500 – 1440 = 60 rpm. Rotor magnetic field is in the same direction of rotation of rotor. (iii) Speed of stator magnetic field w.r.t. stator = N = 1500 rpm.
