WebThe magnetic field in three phase induction motor (RMF) rotates at a constant speed called synchronous speed (Ns), which is given by, N S = 120f 1 /P RPM where f 1 = Frequency of stator supply P = Number of poles of motor. Direction of Rotating Magnetic Field WebIf the magnetic field at a point in space changes, then it is responsible for producing an electric field and that electric field can do work and in fact E → can be line integrated along the circuit, and the result is equal to the flux of ∇ → × E → through the surface determined by the circuit, so equal to the flux of − ∂ B → / ∂ t through the …
Web23 jan. 2014 · The production of Rotating magnetic field in 3 phase supply is very interesting. When a 3-phase winding is energized from a 3-phase supply, a rotating magnetic field is produced. This field is such that its poles do no remain in a fixed position on the stator but go on shifting their positions around the stator.
