基波电枢磁动势对转子齿谐波电动势的影响
Influences of Fundamental Armature MMF on Tooth Harmonic EMF of the Rotor
摘要
Abstract
The research on influence of the fundamental armature magnetic motive force (MMF) on the tooth harmonic electromotive force (EMF) of the rotor is one of the key problems for utilizing inherent tooth harmonic magnetic fields to achieve the adjustment of the air gap magnet field of the permanent magnet machine. The principle of the rotor tooth harmonic EMF generated by the stator fundamental armature MMF was analyzed qualitatively based on the permeability analysis method. The influence of the fundamental armature MMF on the rotor tooth harmonic EMF were discussed for linear and nonlinear magnetic circuits. When the generator is connected with an inductive load, the rotor tooth harmonic EMF decreases as the armature current increases for the linear magnetic circuits. However, for the non-linear magnetic circuits, the rotor tooth harmonic EMF may increase, maintain constant or decrease as the armature current increases. Calculation and experiment are performed for one hybrid excitation permanent magnet synchronous generator utilizing tooth harmonic for excitation, and calculated and experimental results are consistent with theoretical analysis.关键词
