ABSTRACT:
A winding technique for multiphase machines is presented that utilizes a core of Q slots and P poles for M phases where Q/M is an integer but the number of slots per phase per pole Q/M/P is a non-integer expressible as a fraction N/D reduced of common factors and M and D have a common factor of at least two. Fractional-slot, nearly but not quite balanced, windings are provided by providing a distant coil grouping for D poles in which the number of coils in the coil groups for the D poles equals N for an individual phase and the pattern is repeated for the additional poles to provide the total of P pole windings. The near balancing of the windings succeeds in achieving sufficient voltage balancing and low torque harmonics for successful operation and is advantageous for avoiding a need to provide additional core designs.
