Based on the 2-d model of a slot and the effective flux density distribution in an equivalent slotless machine, this paper presents an analytical technique for accurately determining the optimal slot opening for minimum cogging torque in permanent magnet machines. It is then used to derive the relationship between slot opening and cogging torque for machines having different combinations of slot number and pole number. In addition, it is applied to slot pairing to effectively reduce the cogging torque. Analytical results are verified by finite element analyses and experiments.

Wykorzystując dwuwymiarowy model szczeliny i rozkladu indukcji w artykule zaprezentowano technikę określania optymalnej szczeliny dla uzyskania minimalnego momentu zakleszczania się. Analizę wykorzystano do określania momentu w maszynach o różnej liczbie szczelin i biegunów. Wyniki analizy zweryfikowano eksperymentalnie i obliczeniowo (metodą elementu skończonego).
