first embodiment

[0065]The configuration of the lead frame 255 will now be described, where in a first embodiment a single, substantially, circumferential lead frame, as illustrated in FIG. 5, is used for providing current from both control devices to the respective coil sets. As illustrated in FIG. 6 the substantially circumferential lead frame 255 is mounted to an axial mounting surface of a stator back-iron 600, which forms part of the stator 252, adjacent to the coils, where coils are wound on stator teeth formed on the stator back-iron 600.

[0066]The lead frame 255 includes a first set of three apertures 610 for receiving a respective busbar lead frame pin for coupling the lead frame 255 to an inverter 310 in the first control device 300 and a second set of three apertures 620 for receiving a respective busbar lead frame pin for coupling the lead frame 255 to an inverter 310 in the second control device 300, as described below.

[0067]The lead frame 255 is mounted to the stator back-iron 600 via the

second embodiment

[0069]FIG. 7 illustrates the lead frame, where the lead frame comprises a first lead frame section 701 and a second lead frame section (not shown), where preferably both the first lead frame section 701 and the second lead frame section are semi-circumferential such that when mounted on the stator 252 the first lead frame section 701 and the second lead frame section form a substantially circumferential lead frame arrangement. As illustrated in FIG. 8 each lead frame section 701 is mounted to an axial mounting surface of a stator back-iron 600, which forms part of the stator 252, adjacent to the coils, where coils are wound on stator teeth formed on the stator back-iron 600.

[0070]Both the first lead frame section and the second lead frame section includes a set of three apertures 801 for receiving a respective busbar lead frame pin for coupling the first lead frame section 701 and the second lead frame section 701 to an inverter 310 in the first control device 300 and the second contro

Abstract

A lead frame for electrically coupling a plurality of inverter legs of an inverter to a set of coil windings of an electric motor or generator, the lead frame comprising a printed circuit board having a plurality of circuit board layers. Each circuit board layer includes an insulating substrate having an electrically conductive layer formed on the insulating substrate. First, second and third circuit board layers each include a respective electrically conductive layer arranged to be coupled to a corresponding coil winding of the first set of coil windings and a respective inverter leg. A fourth circuit board layer includes a respective electrically conductive layer arranged to be coupled to all of the third coil windings to form a neutral point therebetween.
