Abstract
An electric machine includes a stator with a core having an end face and a plurality of conductors forming windings that extend adjacent to the end face defining end turns having a toroidal outline. The end turns are formed to define at least one channel in the end turns that traverses the end turns for increasing a surface area for fluid contact and directing a flow of fluid along the toroidal surface.
Claims11
An electric machine comprising:
- a stator including a core having an end face and a plurality of conductors forming windings that extend adjacent to the end face and defining end turns having a toroidal outline including an annular surface that is generally parallel to the end face, the end turns formed to define at least one channel that traverses the conductors along the annular surface for increasing surface area and directing a flow of fluid.
An electric machine comprising:
- a stator including a core defining an end face, a plurality of conductors forming windings that extend adjacent to the end face and defining end turns having an annular surface generally parallel to the end face, and insulating elements and binding elements disposed in contact with the conductors, wherein the end turns are formed to define at least one channel that traverses the annular surface that includes the conductors, the insulating elements, and the binding elements.
