摘要： We describe a method of manufacturing a housing for the stator of an axial flux permanent magnet machine, in particular a Yokeless and Segmented Armature motor, the machine having a stator comprising a set of coils wound on respective stator bars and disposed circumferentially at intervals about an axis of the machine, and a rotor bearing a set of permanent magnets and mounted for rotation about said axis, and wherein said rotor and stator are spaced apart along said axis to define a gap therebetween in which magnetic flux in the machine is generally in an axial direction. The method comprises: fabricating a radial wall for said stator housing to be located in said gap between said rotor and said stator by: providing a membrane of fibre-reinforced polymer material; pressing a set of said stator bars into said membrane of fibre-reinforced polymer whilst said polymer is mouldable, wherein said reinforcement inhibits said stator bars from pushing through said membrane; solidifying said polymer to hold said set of stator bars in their respective positions; and manufacturing said housing using said radial wall.

摘要： An axial flux machine is described. The machine has a stator comprising a stator housing enclosing a plurality of stator bars disposed circumferentially at intervals around an axis of the machine, and a rotor comprising a set of permanent magnets and mounted for rotation about the axis of the machine. The rotor is spaced apart from the stator along the axis of the machine to define a gap between the stator and rotor and in which magnetic flux in the machine is generally in an axial direction. The machine also comprises a hub assembly comprising a rotating hub and a mount separated by a bearing to permit the hub to rotate relative to the mount, the rotating hub comprising a hub flange and the mount comprising a mount flange, each of the flanges being spaced axially apart from one another. The machine further comprises a bulkhead for mounting the hub assembly and stator, wherein the bulkhead is mounted to the mount flange of the hub assembly and the stator housing is mounted to the bulkhead. The rotor comprises first and second rotors disposed either side of the stator, the first rotor being mounted to the hub flange and the second rotor being mounted only to the first rotor, the first and second rotors together forming a U-shaped rotor extending across and either side of the stator and being rotatable relative to the stator about the axis of the machine.
