    Abstract: A rotor for an axial flux permanent magnet machine is described. The machine has a stator comprising a stator housing enclosing a set of coils wound on stator bars or teeth and disposed circumferentially at intervals about an axis on the machine, and a rotor bearing a set of permanent magnets and mounted for rotation about the said axis. The rotor and stator are spaced apart along said axis to define a gap therebetween in which magnet flux in the machine is generally in an axial direction. The magnets are disposed circumferentially around said rotor and define a plurality, n, of matching sets of magnets. Each set of magnets includes a plurality of magnets, wherein said n sets of magnets on said rotor have n-fold rotational symmetry. Within a said set, the magnets have different shapes and/or relative circumferential spacings of adjacent magnets within the set of magnets are irregular.

    Abstract: An electric machine (10) comprises a rotor (14a, b) having permanent magnets (24a, b) and a stator (12) having coils (22) wound on stator bars (16) for interaction with the magnets across an air gap (26a, b) defined between them. The bars (16) and coils (22) are enclosed by an annular stator housing (42a, b) that extends between the air gap. A chamber (52, 54, 56) is defined that incorporates cooling medium to cool the coils. The stator housing comprises two mating clamshells (42a, b) that mount the stator bars and coils in the machine. Each clamshell is molded from reinforced plastics and interconnected (optionally through one or more intermediate components). At least one clamshell has over-molded therein stator bar shoes that form part of said radial wall, and optionally one or more of the following components: cylindrical boss supports extending along the cylindrical outer wall part; connection studs that communicate electrically the chamber externally; stator coils; coolant inlet and outlet ports; and an outer race of a rotor bearing.

    Abstract: A wheel-hub motor (100) comprises a rotor (14) having permanent magnets, although other field generation means are available, and a stator (12). The stator has coils (22) wound on stator bars (16) for interaction with the magnetic field of the rotor across an air gap (26a,b) defined between them. The stator (12) forms a housing of a chamber (70) containing refrigerant (82). The stator housing has heat dissipating fins (96) accessible by the open environment whereby air movement relative to the housing caused at least by rotation of the rotor absorbs heat from the fins. The motor may be an axial flux machine, the coils being wound on bars that are disposed circumferentially spaced around a rotation axis (80) of the rotor. The wheel of the vehicle is mounted directly on the rotor housing.
