Abstract :
The paper discusses the guidelines for designing concentrated winding fractional slot permanent magnet machines. The winding factor and different slot and pole combinations are studied. Various low-speed high-torque permanent magnet synchronous motors with concentrated windings and with different slot and pole combinations are calculated analytically and by applying the finite element method (Flux2D¿ by Cedrat). All the motors calculated in this study have the same frame size, air-gap diameter, air-gap length and the same amount of permanent magnet material.
