Description
Summary:This paper deals with the magnetic analysis and the design of fractional slot PM motors with non overlapped coils. A particular care is given to the stator current reaction and the computation of the self and mutual inductances. The effort of this paper is to give an analytical prediction of these quantities. Simple but effective rules are given to a rapid choice of the motor geometry, with a special care of the combinations of number of poles and number of slots, as well as the winding types. Finite element simulations and experimental results confirm the analytical predictions. The effort of this paper is to find a method for the choice of the combination of the number of slot and poles of the machine.
