Abstract

This paper deals with the design of a pole change single-phase induction motor to reduce the harmonic components of the magnetic flux density in the air gap. The harmonics in the magnetic flux density distribution can have a significant detrimental effect on the characteristics of the machine such as crawling. In this paper, the magnetic flux density distribution is analyzed by analytical method and finite element method. Discrete Fourier transform is used to analyze the harmonics and the characteristics are calculated from the equivalent circuit considering the harmonic components. The winding arrangement for the harmonic reduction is designed from the optimization method and the harmonic reduction of the improved models is verified through the experimental results.
