Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An endplate for an electric machine, comprising: a disc-like body defining a plurality of openings and a corresponding channel extending from each of the plurality of openings, the corresponding channels extending from each of the plurality of openings to a distal diameter of the disc-like body, the plurality of openings configured to allow coolant to pass therethrough, wherein at least a portion of the plurality of openings are lift points configured to facilitate picking and placing the electric machine; a lip arranged around a circumference of the disc-like body and extending therefrom, the lip configured to guide the coolant into the plurality of openings to supply coolant at an end winding of a stator of the electric machine; and a lid arranged on the disc-like body and configured to maintain the coolant within the lid and guide the coolant into the least one opening, wherein the lid defines at least one notch to correspond to the corresponding channel in the installed state. 2. The endplate of claim 1 , wherein at least a portion of the plurality of openings are cooling holes configured to allow fluid to move through the endplate. 3. The endplate of claim 1 , wherein the plurality of openings are equidistantly and circumferentially arranged around the disc-like body. 4. An endplate for an electric machine, comprising: a disc-like body defining a plurality of openings and a corresponding channel extending from each of the plurality of openings, the corresponding channel extending from the at least one opening to a distal diameter of the disc-like body, at least one of the plurality of openings configured to allow coolant to pass therethrough, wherein at least a portion of the plurality of openings are lift points configured to facilitate picking and placing the electric machine and wherein the plurality of openings are equidistantly and circumferentially arranged around the disc-like body; a lip arranged around the distal diameter of the disc-like 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 lid arranged on the disc-like body to maintain the coolant within the lid and guide the coolant into the least one opening, wherein the lid is a ring-like shape configured to be bolted to the disc-like body and wherein the lid defines at least one notch to correspond to the corresponding channel in the installed state. 5. The endplate of claim 4 , wherein at least a portion of the plurality of openings are cooling holes configured to allow fluid to move through the endplate, and wherein the cooling holes are arranged in alternate arrangement with the lift points.
