the movement of magnetic field in field winding of induction
machine. it moves in the clock wise or anti clockwise
direction but when this rotating magnetic field is equal to
the speed of the rotor then rotor will be in the lock out
condition. when the rotating magnetic field is less than
rotor speed. this is case in the Induction machines.
Ns=120f/P

Answer / coolclikker

Rotating magnetic field refers to the movement of magnetic
flux or field in stator winding around the rotor. this field
is generated by the poles on the stator of induction
machine. rotating magnetic field plays an important role of
magnetic induction and emf which is generated on the rotor
of the induction machine.
