Abstract
An electric machine assembly having a main machine stator core having at least one stator post, a set of stator windings wound about the at least one stator post and having a first end and an opposing second end, a coolant inlet housing defining an inlet passage, a coolant outlet housing defining an outlet passage, proximate to the coolant inlet housing, and wherein the coolant inlet passage and the coolant outlet passage define a coolant circuit configured to receive a supply of coolant to remove heat generated in the set of stator windings.
Claims20
An electric machine assembly comprising:
- a main machine stator core having at least one stator post;
- a set of stator windings wound about the at least one stator post and having a first end and an opposing second end, the stator windings defining a fluid channel disposed through the stator windings configured to carry a flow of coolant;
- a coolant inlet housing defining an inlet passage disposed at an axial end of the electric machine assembly fluidly connected with the fluid channel of the first end of the set of stator windings;
- and
- a coolant outlet housing defining an outlet passage disposed at the axial end of the electric machine assembly, proximate to the coolant inlet housing, and fluidly connected with the fluid channel of the second end of the stator windings;
- wherein the coolant inlet passage, the fluid channel of the stator windings, and the coolant outlet passage define a coolant circuit configured to receive a supply of coolant to remove heat generated in the set of stator windings.
