摘要: The permeance between the small teeth provided on stator magnetic pole and rotor may be varied regularly according to rotation of rotor. tip end each are divided into sets two or three at least one pitch adjacent is different from other teeth, so that vector sum quaternary harmonics in set substantially zero. formed composed a tertiary included becomes zero, permeances axialsymmetric harmonic plane
