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: A double-rotor single stator axial flux machine, which is supplied having no bearings between the rotors and stator internal of the machine, is mounted to an external structure such as an interface of an engine of a vehicle or a portion of the transmission of a vehicle. The machine is mounted to the structure via the shaft of the machine (on which are seated bearings located in the structure) and the stator housing. The bearings of the structure, which are external to the machine, permit the rotors to rotate relative to the stator when the machine is installed on the structure.
