Effect of Increasing Pole Number on the Harmonic Content of Air-gap Flux Density Waveforms in Electric Machines

Abstract

This paper studies the effects of increasing the number of rotor poles on air gap flux density waveforms. The aim is to reveal the harmonic behavior of the working flux in the air gap, which controls the performance, and the operational behavior of the whole machine. A permanent magnet motor is used to perform the analysis and study the effects. Its… (More)
