The Principle Of Frequency Inversion

Induction motor fed by ac current, typically three-phase. Three-phase system of windings creates a rotating magnetic field with an angular velocity of rotation: (1) where f – frequency of the mains, pn – number of pole pairs. Rotating magnetic field crosses the winding turns of the rotor. If the rate of rotation of the rotor …
