Influence of Different Modulation Strategies on Losses for Flux Switching Permanent Magnet Machine
摘要
The efficiency of flux switching permeant magnet (FSPM) machine is a research focus in recent years. However, researches on different modulation strategies on iron loss are limited. In this paper, the influence of different rotor speeds on iron loss, eddy current loss, hysteresis loss is investigated. Each order harmonic in the rotor is also analyzed to learn about the constitute of iron loss. Then, magnetic flux density in the air gap when the machine is no load and supplied by pulse width modulation (PWM) inverter is calculated. Finally, iron loss and copper loss under different PWM strategies and working conditions are investigated by finite element analysis (FEA).
