turn arc

The harmonic influence of each structural parameter on the fractional slot motor can be achieved by changing four structural parameters in turn. The four structural parameters are width of slot opening, air-gap size, pole arc coefficient and thickness of magnet.

其次通过逐次改变影响电机转矩脉动的四种结构参数，其包括槽口宽度，气隙尺寸，极弧系数和永磁体厚度，找到每种结构参数对分数槽永磁电机齿谐波影响的映射关系。
