Rotating magnetic field in three phase induction motor
Answers
Answer:
The induction motor rotates due to the rotating magnetic field in 3 phase induction motor which is produced by stator winding in air gap between in stator and rotor. Stator has a three phase stationary winding which can be either star connected or delta connected.

Rotating magnetic field in 3 phase Induction motor.
Explanation:
The Induction Motor rotates due to the rotating magnetic field in Three phase Induction Motor. It is produced by the Stator Winding in the air gap between in the stator and rotor. The stator has a three phase stationary winding which can be either star connected or delta connected.
Mathematically, represented as
∅R = ∅msinωt = φmsinθ
φB = φmsin (ωt-120)
∅Y = ∅m sin(ωt-240)
the total flux in the air gap is equal to the phasor sum of these three phases
