INDUCTION ELECTRIC MACHINE

摘要

The present invention pertains to the construction of alternative-current electric machines that include separate magnetic conductors. The purpose of this invention is to eliminate the zero-induction areas on the outer surface of the plate packs of the stator and on the inner surface of the rotor, and to provide a more efficient use of the windings. To this end, the electric machine inductor comprises a stator made of a magnetic conductor and in the form of several dented laminated packs, at least one winding and a rotor. The packs have a PI shape and are regularly arranged at the periphery so as to define teeth within the air gap of the machine. The magnetic conductor consists of a dented and laminated pack made of electric-furnace steel and defining a multiple-turn solenoid, wherein the outer surface of said turns is isolated. Each turn thus includes teeth on its inner surface as well as yokes on its outer surface which are laminated in the longitudinal plane.
