Abstract
A stator core and method of forming a stator assembly for an electric machine, including a cylindrical stator core, a set of posts extending radially inward from the stator core defining a set of slots between adjacent posts, and a set of windings formed by conductive wire wound in a fewer than all of the set the slots, defining a first subset of wound slots and a second subset of empty slots.
Claims20
A stator assembly for an electric machine, comprising:
- a cylindrical stator core;
- a set of posts extending radially inward from the stator core defining a set of slots between adjacent posts;
- and
- a set of windings formed by conductive wire wound in a fewer than all of the set the slots, defining a first subset of wound slots and a second subset of empty slots;
- wherein a subset of posts facing a respective empty slot are adapted to resist circumferential bending toward to the respective empty slot.

A method of forming a stator assembly for an electric machine, comprising:
- providing a cylindrical stator core having a set of posts extending radially inward from the stator core defining a set of slots between adjacent posts, the set of slots comprising a first subset of winding slots and a second subset of empty slots, wherein a subset of posts facing the a respective empty slot are adapted to resist circumferential bending toward to the respective empty slot;
- and
- winding conductive wiring about a subset of the posts to occupy the first subset of winding slots with the conductive wiring.
A stator core, comprising:
- a cylindrical core base;
- and
- a set of posts extending radially inward from the stator core defining a set of slots between adjacent posts, wherein at least a subset of the posts define a first side facing a first slot, the first side having a polygonal form, and a second side facing a second slot, opposite the first slot, the second side having a parabolic form;
- wherein the subset of posts are adapted to resist circumferential bending toward to the second slot.
