Abstract: We describe a method of manufacturing a housing for the stator of an axial flux permanent magnet machine, 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 comprising: fabricating a radial wall for said stator housing to be located in said gap between said rotor and said stator by: placing a resin membrane into a mold of an injection molding machine; injection molding a set of reinforcing features onto said membrane using a thermoplastic polymer bondable when molten with said resin; and manufacturing said housing using said radial wall.
