Abstract
A stator core is provided that can define a plurality of core slots in a surface thereof. The core slots can extend between a first and a second end portion of the stator core. A winding can be housed in the core slots. The winding can define a channel through at least a portion thereof. A cooling system can be operably coupled with the channel and can be configured to move a cooling fluid through the channel. A turbulator can be positioned within the channel. The turbulator can be within a flowpath of the cooling fluid and can be integrally formed with the winding.
Claims20
An electric machine comprising:
- a stator core defining a plurality of core slots in a surface thereof;
- a winding housed in at least one of the plurality of core slots, the winding defining a channel through at least a portion thereof;
- a cooling system operably coupled with the channel and configured to move a cooling fluid through the channel;
- and
- a turbulator positioned within the channel, wherein the turbulator is within a flowpath of the cooling fluid.
A method of manufacturing an electric machine having a stator core and a rotor, the method comprising:
- for the stator core of the electric machine, forming a winding having a channel defined through at least a portion thereof, wherein forming the winding further includes integrally forming one or more turbulators within the channel.
A winding for an electric machine comprising:
- an elongated body, wherein the elongated body is configured to be operably coupled with at least one of a stator or a rotor;
- a channel defined by the elongated body and extending through at least a portion of the elongated body;
- and
- a turbulator positioned within the channel, wherein the turbulator is within a cooling fluid flowpath through the channel.
