Abstract
An endplate for an electric machine may include a disc-like body defining at least one opening and a corresponding channel extending therefrom, the channel extending from the at least one opening to a distal diameter of the body, the opening configured to allow coolant to pass therethrough, and a lip arranged around a circumference of the body and extending therefrom, the lip configured to guide the coolant into the at least one opening to supply coolant at an end winding of a stator of the electric machine.

An endplate for an electric machine, comprising:
- a disc-like body defining at least one opening and a corresponding channel extending therefrom, the channel extending from the at least one opening to a distal diameter of the body, the opening configured to allow coolant to pass therethrough;
- and
- a lip arranged around a circumference of the body and extending therefrom, the lip configured to guide the coolant into the at least one opening to supply coolant at an end winding of a stator of the electric machine.
An endplate for an electric machine, comprising:
- a disc-like body defining at least one opening and a corresponding channel extending therefrom, the channel extending from the at least one opening to a distal diameter of the body, the at least one opening configured to allow coolant to pass therethrough;
- a lip arranged around the distal diameter of the body and configured to guide the coolant into the at least one opening to supply coolant at an end winding of the electric machine;
- and
- a cover configured to abut and cover the lip to maintain the coolant within the cover and guide the coolant into the least one opening.
A vehicle electric machine, comprising:
- a stator including end windings extending axially from the stator;
- a rotor disposed within the stator and including two rotor endplates, each endplate having a disc-like body defining at least one opening configured to allow coolant to pass therethrough;
- and
- an annular ring configured to abut and cover a portion of the body of one of the two rotor endplates, the annular ring having a plurality of radially extending channels configured to direct coolant from the at least one opening of the end plate to the end windings of the stator during operation of the electric machine.
