Abstract
In this chapter, the theoretical and experimental investigation was performed using two-pole 2.2 kW three-phase induction motor. Also, the same motor was analyzed after replacing its single-layer preformed winding (q = 4) with the single-layer preformed six-phase winding (q = 2) selected on the basis of conducted design calculations. In both scenarios, the windings of this motor with different numbers of phases induced a two-pole rotating magnetic field with completely identical electromagnetic parameters (kef1 = kef2 = 0.914). When performing experimental tests of the motors under different loads, the three-phase motor was supplied with the nominal voltage of 230 V, and the six-phase motor was supplied using lowered six-phase symmetric voltage of 130 V. Based on the results of experimental tests, the calculation of operating characteristics using segregated-losses method was completed. These characteristics of the three-phase and six-phase motors were compared graphically.
