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.
