Title: Reduction of the high harmonics at the electromagnetic force and the electromagnetic torque in synchronous machines with permanent magnet
Keywords: permanent magnet with “V” form, synchronous machine, finite element method, stator’s winding.

Abstract: This paper presents the results from a study of permanent magnet synchronous machines, with magnets positioning in the rotor form like “V”. The following types of stator winding (these are the main possibilities for these values of stator slots -Z and pair of poles-p) are investigated: Case 1- three-phase, single-layer, full-pitch coil, integral-slot stator winding (3FFPW); Case 2- three-phase, double-layer, short-pitch coil, integral-slot stator winding (3FSPW); Case 3- three-phase, single-layer, full-pitch coil, skew slots, integral-slot stator winding (3FSSW); Case 4- five-phase, double-layer, short-pitch coil, fractional-slot stator winding (5FSPW). The conducted analysis is based on the application of finite element method. The benchmark for the results obtained are the amplitude of the first harmonic of the e.m.f. and electromagnetic torque and harmonic order. The research in this article is based on the application of the 2D software computer package FEMM 4.2.
