Abstract
An electric machine can include a stator core having a plurality of core teeth that define a plurality of core slots in a surface thereof. A winding can be housed at least partially in the core slots. The winding can include a tube defining a channel through at least a portion thereof and one or more wires disposed along a surface of the tube that is opposite the channel. A cooling system can be operably coupled with the channel and configured to move a cooling fluid through the channel.
Claims20
An electric machine comprising:
- a stator core defining a plurality of core slots in a surface thereof;
- a winding positioned at least partially in one of the plurality of core slots, the winding including a tube defining a channel through at least a portion thereof and one or more wires disposed along the tube opposite the channel;
- and
- a cooling system operably coupled with the channel and configured to move a cooling fluid through the channel.
A method of manufacturing an electric machine, the method comprising:
- positioning one or more wires about a surface of a tube to form a winding, wherein the tube defines a channel through at least a portion thereof, and wherein the one or more wires are separated from the channel by the tube;
- operably coupling the winding to one of a stator core or a rotor of the electric machine;
- and
- fluidly coupling a cooling system to the channel.
A winding assembly for an electric machine comprising:
- a tube defining a channel through at least a portion thereof, the tube configured to be operably coupled with a stator or a rotor of the electric machine;
- and
- one or more wires, the one or more wires positioned along the tube opposite the channel.
