Abstract :
This work deals with the calculus of expressions for the complex winding factor from the star of slots directly obtained from the type of the fractional winding. Complex winding factor expressions have been obtained for Q slots and p pole pair combination and have been included in an analytical model based on spatial Fourier series. The model is achieved for a slotless stator and surface mounted permanent magnet rotor. The accuracy of the model is evaluated with FEM simulations for both slotted and slotless stator.
