Abstract
The effect of tooth shape on radial forces inside the air-gap acting on the stator for a typical step motor tooth profile have been investigated by 3D finite element method. It has been found that the radial force acting on the stator varies from high to low value due to rotor movement. The magnitude of the variation depends on the tooth shape and the stator and rotor tooth to valley ratio and level of saturation. The result have shown that rectangular tooth shape with stator tooth to valley ratio of 1:1 and rotor tooth to valley ratio of 1:3 is the best for reducing radial force variation for the cases studied.
