Electric motor with coolant flow at stator slots

An electric motor, comprising:

• a stator assembly comprising:
• a plurality of laminations with an axially-stacked arrangement, the plurality of laminations establishing coolant channels among the plurality of laminations at a radially-outboard location of the plurality of laminations, the plurality of laminations establishing slots at a radially-inboard location of the plurality of laminations, working slots of the slots having increased radially-outward extents, the increased radially-outward extents fluidly communicable with working coolant channels of the coolant channels;
• conductors residing at the slots;
• and
• a plurality of liners situated in the slots at least partially around the conductors, the plurality of liners having at least one coolant hole residing therein, the at least one coolant holes fluidly communicable with the increased radially-outward extents of the working slots.

An electric motor, comprising:

• a housing;
• a rotor assembly at least partially located in the housing;
• and
• a stator assembly at least partially located in the housing, the stator assembly comprising:
• a plurality of laminations with an axially-stacked arrangement, the plurality of laminations having a plurality of fins, the plurality of fins establishing coolant channels among the plurality of laminations at a radially-outboard location of the plurality of laminations, the plurality of laminations establishing slots at a radially-inboard location of the plurality of laminations, working slots of the slots fluidly communicable with working coolant channels of the coolant channels;
• conductors residing at the slots;
• a plurality of liners situated in the slots at least partially around the conductors, the plurality of liners having at least one coolant hole residing therein, the at least one coolant holes fluidly communicable with the working slots;
• and
• a plurality of inserts situated in the working slots.
