Emily YANG - Web page: https://patentgrep.com/patent/US20210242746A1 ## CPC - H02K 5/15: Mounting arrangements for bearing-shields or end plates - H02K 5/203: {specially adapted for liquids, e.g. cooling jackets} - H02K 9/19: for machines with closed casing and closed-circuit cooling using a liquid cooling medium, e.g. oil - H02K: DYNAMO-ELECTRIC MACHINES (dynamo-electric relays H01H53/00; conversion of DC or AC input power into surge output power {H03K3/53}) ## 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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The endplate of claim 1, further comprising 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. ### Claim 3 (depends on 2) The endplate of claim 2, wherein the cover is a ring-like shape configured to be bolted to the body. ### Claim 4 (depends on 2) The endplate of claim 2, wherein the cover defines at least one notch to correspond to each channel in the installed state. ### Claim 5 (depends on 1) The endplate of claim 1, wherein the at least one opening includes a plurality of openings. ### Claim 6 (depends on 5) The endplate of claim 5, wherein at least a portion of the plurality of openings are lift points configured to facilitate picking and placing the electric machine. ### Claim 7 (depends on 5) The endplate of claim 5, wherein at least a portion of the plurality of openings are cooling holds configured to allow fluid to move through the endplate. ### Claim 8 (depends on 5) The endplate of claim 5, wherein the plurality of openings are equidistantly and circumferentially arranged around the body. ### Claim 9 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. ### Claim 10 (depends on 9) The endplate of claim 9, wherein the cover is a ring-like shape configured to be bolted to the body. ### Claim 11 (depends on 10) The endplate of claim 10, wherein the cover defines at least one notch to correspond to each channel in the installed state. ### Claim 12 (depends on 10) The endplate of claim 10, wherein the at least one opening includes a plurality of openings. ### Claim 13 (depends on 12) The endplate of claim 12, wherein at least a portion of the plurality of openings are lift points configured to facilitate picking and placing the electric machine. ### Claim 14 (depends on 12) The endplate of claim 12, wherein at least a portion of the plurality of openings are cooling holds configured to allow fluid to move through the endplate. ### Claim 15 (depends on 12) The endplate of claim 12, wherein the plurality of openings are equidistantly and circumferentially arranged around the body. ### Claim 16 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. ### Claim 17 (depends on 16) The vehicle of claim 16, wherein the annular ring comprises an axially extending lip arranged around an outer circumference and configured to guide the coolant into the at least one opening to supply coolant to the end windings. ### Claim 18 (depends on 17) The vehicle of claim 17, wherein the annular ring is configured to be bolted to the body of the endplate. ### Claim 19 (depends on 16) The vehicle of claim 16, wherein each of the plurality of radially extending channels extends from an interior circumference to an exterior circumference of the annular ring. ### Claim 20 (depends on 16) The vehicle of claim 16, wherein the at least one opening includes a plurality of openings.
