Abstract
A multiphase motor comprises a plurality of ferromagnetic stator core segments, the core segments being substantially uniformly spaced around an axis of rotation and isolated from direct contact with each other. Each core segment forms at least one pair of poles having coils wound thereon to form a phase winding. Each stator phase winding is configured with a topology different from the topology of each of the other phase windings. Each phase winding has a different total number of coils from one or more of the other phase windings. Each phase winding comprises coils of a gauge different from the coil gauge of one or more of the other phase windings. Preferably, all of the phase windings have substantially the same total coil mass.
