Axial Flux Machine Manufacture

Abstract: A method of manufacturing permanent magnets for an axial flux permanent magnet machine. The axial flux permanent magnet machine comprises a stator with a set of coils disposed circumferentially at intervals about a machine axis, and a rotor bearing a set of permanent magnets disposed circumferentially at intervals about the machine axis. The rotor and stator are spaced apart to define a gap in which magnetic flux is generally in an axial direction. The method comprises, for each (permanent) magnet, mounting the magnet in a magnet fixture in a cutting position relative to a cutting machine configured to cut along an array of cutting lines, and moving the magnet and the array of cutting lines to simultaneously make an array of cuts across the magnet, each extending through a thickness of the magnet. The cutting machine may be a wire cutting machine.
