The Influence of Pole-Slot Match on Magnetomotive Force with Concentrated Fractional-Slot Winding

Abstract:

Magnetic field, produced by magnetomotive force (MMF) harmonic waves, is harmful to motors, by reducing efficiency of motors, resulting in demagnetization of permanent magnets and so on. It is also responsible for the increase of eddy current loss and the rise of temperature of rotors. Thus, research on the influence of pole-slot match on MMF with concentrated fractional-slot winding is necessary. This paper aims at researching unit motors with different cooperation of slots and poles. First, basic principle of MMF is described. Then, with different kinds of unit motors, MMF of harmonic waves is analyzed. Based on these analyses, distributive regularities are summarized.
