Abstract
An electric machine stator is provided and includes laminations consolidated along an axial direction to form a core element such that the core element includes an end lamination at an axial end of the core element. The end lamination includes a body extending in a plane and a plurality of spacer protrusions protruding along the axial direction from the plane. Each of the spacer protrusions of the plurality of spacer protrusions is configured for consolidation with another core element to define a radial vent between the core element and the another core element.
Claims20
An electric machine stator, comprising:
- laminations consolidated along an axial direction to form a core element such that the core element includes an end lamination at an axial end of the core element,
- the end lamination comprising:
- a body extending in a plane;
- and
- a plurality of spacer protrusions protruding along the axial direction from the plane, the plurality of spacer protrusions being configured for consolidation with another core element to define a radial vent between the core element and the another core element.
A stator of an electric machine, comprising:
- first laminations consolidated along an axial direction to form a first core element;
- and
- second laminations consolidated along the axial direction to form a second core element,
- the first and second core elements being disposable such that a first end lamination of the first core element faces a second end lamination of the second core element,
- the first end lamination comprising a body extending in a plane and a plurality of spacer protrusions protruding along the axial direction from the plane, the plurality of spacer protrusions being configured for consolidation with the second end lamination.
A method of assembling an electric machine stator, the method comprising:
- consolidating first and second laminations along an axial direction to form first and second core elements, respectively, such that a first end lamination of the first core element faces a second end lamination of the second core element;
- and
- forming the first end lamination to include a body extending in a plane and a plurality of spacer protrusions protruding along the axial direction from the plane;
- and
- consolidating the plurality of spacer protrusions with the second end lamination along the axial direction.
