An electric machine comprising:
- a housing;
- a stator mounted within the housing;
- and
- a rotor rotatably mounted relative to the stator, the rotor including a spool assembly, the spool assembly including:
- a spool including a main body portion including a first end portion that extends substantially uninterrupted to a second end portion through an intermediate portion, the spool including a first plurality of mounting elements provided on the first end portion and a second plurality mounting elements provided on the first end portion;
- and
- a star member secured to the first end portion of the spool, the star member including a main body having a central opening and a plurality of mounting members that extend radially into the central opening, the plurality of mounting members constraining axial movement of the star member relative to the spool in a first direction and the first plurality of mounting elements constraining axial movement of the star member relative to the spool in a second direction.
A spool for an electric machine, the spool comprising:
- a main body portion including a first end portion that extends substantially uninterrupted to a second end portion through an intermediate portion, the main body being devoid of annular flanges at the first and second end portions;
- and
- a plurality of mounting elements provided on the first end portion, the plurality of mounting elements includes first plurality of mounting elements and a second plurality of mounting elements, the first plurality of mounting elements being distinct from the second plurality of mounting elements, wherein the first plurality of mounting elements comprise a plurality of projections extending radially outward from the first end portion.
