A stator and busbar assembly for an electric supercharger

The motor includes a stator assembly 201 comprising a plurality of pairs of windings 203A-C, each pair of windings 203A-C comprising a first winding for forming a first pole and a second winding for forming a second, opposite, pole, each winding having an input termination 205 and an output termination 207. The stator assembly further comprises a plurality of pairs of identical busbars 209A-C, each pair of busbars being associated with a respective pair of windings 203A-C. Each pair of busbars 209A-C comprises an input busbar 211 connecting the input terminations 205 of the first and second windings in the respective pair of windings, and an output busbar 213 connecting the output terminations 207 of the first and second windings in the respective pair of windings 203A. A tab 215 associated with each bushbar connects to the control modules for selectively energising pairs of windings and an insulating housing 217fits over the bus bar assembly and includes attachment feet 219 for connection to the stator assembly (fig 6 not shown).
