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.

There is provided an axial flux motor comprising one or more rotating disks () and a stator () comprising a cavity () formed between walls () and containing therein more than one electro-magnetic coil assembly (). Each electro-magnetic coil assembly () comprises more than one pole piece (), each having an axially extending shank portion () and first and second radially extending end shoes () and one or more associated coils (), each of the one or more associated coils () being wound around a shank portion (), wherein said outer surface () of said end shoes are preferably joined to one or other of said walls (). One or both of said first or second shoes further comprise a heat exchange surface () facing a coil () wound around the shank () such as to define first cooling channels () between one or both of said heat exchange surface () and said coil (), and a second flow channel () defined by the spacing of said coil () and adjacent coils ().

A process for manufacturing indium tin oxide (ITO) sputtering targets as described. The process includes the precipitation of indium and tin hydroxides, sintering in the absence of chloride ions, using the resultant oxide powders to prepare an aqueous slip with dispersing agent, binder, special high density promoting agents and compacting the slip in a specially surface coated porous mold using the method of slip casting followed by sintering the resultant compacted target body to yield high density ITO target.
