  • Patent number: 6847147
    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.

  • Patent number: 6271608
    Abstract: An AC generator comprises a rotor 25 within a stator 24. The rotor carries a fan 27 at one end of the stator. The fan 27 is within a casing 30 which forms volume discharge passages 32. The fan 27 has blades 31 which project from the hub 28 at an angle which is oblique to the radial whereby those blades 31 trail the radial. The stator windings 23 form terminal leads 34 which are led from the end of the stator 24 remote from the fan 27. A circumferential array of cleats 35 which each have the form of a comb, support and guide the terminal leads 34 circumferentially, spaced from one another, to a certain location at the top from which the leads are taken and connected to terminals above. Those terminals are formed by the lower ends of busbars (56 to 58, 61 to 69) which extend through and which are supported by a structural panel of insulating material which forms an insulating barrier between the ends of those busbars.
