Abstract
A stator connected to a power supply includes a plurality of wound segment assemblies, each wound segment assembly comprising a segmented corepack stack with a phase winding wound around said segmented corepack stack and a power printed circuit board assembly comprising a printed circuit board (PCB). The stator also includes phase wires connected to said phase winding, said phase wires being connected to said PCB and said PCB being connected to said power supply.
Claims11
A stator connected to a power supply, said stator comprising:
- a plurality of wound segment assemblies,
- each wound segment assembly comprising a segmented corepack stack with a phase winding wound around said segmented corepack stack,
- said stator further comprising:
- a power printed circuit board (PCB) assembly comprising a printed circuit board (PCB),
- said phase winding being connected to phase wires, said phase wires being connected to said PCB and said PCB being connected to said power supply;
- and
- insulation means to insulate the phase winding (201) from the segmented corepack stack (100),
- wherein said insulation means comprises first and second Slot Liners (902) and Phase Separators (801),
- wherein the segmented corepack stack (100) and the slot liner (902) both have an outer ‘T’-shape and the phase separator (801) comprises a sheet having an ‘r’-shaped cross-section,
- said sheet being assembled onto a side of the segmented corepack stack (100) and positioned so that the top portion of the ‘r’-shape is positioned between the underside of the portion (15) of the corepack segment stack (100) that forms the top part of the ‘T’-shape and the upper side of the portion (115) of the slot liners (902) that forms the ‘T’-shape.
