STATOR WEDGE FOR AN ELECTRIC MACHINE
First Claim
1. An electric machine comprising:
- a stator core comprising;
a central opening and a plurality of teeth facing inwardly toward the central opening; and
slots defined between adjacent teeth;
a rotor extending through the central opening;
a gap between the stator core and the rotor;
one or more coils extending through one or more of the slots; and
a wedge disposed in at least one of the slots.

Abstract
Electric machines with, and related methods for, improved fluid flow through the electric machines are disclosed. According to some implementations, an electric machine may include a central opening and a plurality of teeth facing inwardly toward the central opening. Slots may be defined between adjacent teeth, and a wedge may be disposed in one or more of the slots, partitioning the slots into a coils portion and an open portion. A gap may be defined between the stator core and the rotor. A fluid flow path defined from the gap and the open portions of the slots provide for improved fluid flow through the electric machine. Wedges disposed in the slots to maintain the coils into a packed state.

19. A method for increasing an amount of fluid passing through an electric machine between a stator core and a rotor, the method comprising:
-
partitioning a plurality of gaps defined between adjacent teeth of the stator core with wedges, the gaps partitioned to form coils portions and open portions, the open portions opening inwardly towards a central region of the stator core and communicating with a radial gap defined between the stator core and the stator core to form a fluid flow path; and flowing fluid through the fluid flow path to cool the electric machine. - View Dependent Claims (20, 21)
