Abstract
A coil arrangement for an N-phase electrical machine WI includes a first coil 10a and N-1 separate interlocking coils 10b, 10c each including a strip of electrically conductive material that is wound to form a coil having multiple windings circumscribing a hollow core with air gaps between adjacent windings. Ferromagnetic material 1, or a stack of ferromagnetic slices, is disposed within at least some of the air gaps. The first coil 10a serves as an anchor for 10 supporting the N-1 remaining coils and the hollow core of the first coil 10a is dimensioned to accommodate the N-1 remaining coils without shorting between coils. Each remaining N-1 coil 10b, 10c can have a stepped part 21 that is mounted within the hollow core of the first coil 10a. The N-1 coils can be mounted either side of the first coil and, for a five phase or greater machine each successive pair of coils have a deeper stepped portion 21. The coils can be connected using vias or jumpers (fig 4, 12) with unconnected ends (fig 5, 26,27) connected to a source of current. The coil can be used in an axial flux electrical machine such as an induction motor having a rotor (fig 6, 31) with inner and outer rims connected by radial conductive spokes or a radial flux machine having a rotor cage with end plates and axial conductors (Fig 9, 47). In each case ferromagnetic material (fig 7, 17) is disposed within the gaps between the conductors.
