Abstract
An end plate for a rotor of a switched reluctance motor is disclosed. The end plate includes an annular body and a plurality of ribs. The annular body has a first axial end, a second axial end, and a thickness. Further, the annular body defines an outer surface and a bore configured to receive a shaft of the rotor. The plurality of ribs extends radially outwardly from the outer surface. The plurality of ribs is adapted to respectively abut with a plurality of poles of the rotor.
Claims20
An end plate for a rotor, the end plate comprising:
- an annular body having a first axial end, a second axial end, and a thickness,
- the annular body defining an outer surface and a bore configured to receive a shaft of the rotor;
- and
- a plurality of ribs extending radially outwardly from the outer surface,
- the plurality of ribs being adapted to respectively abut with a plurality of poles of the rotor,
- at least one of the plurality of ribs or the plurality of poles being covered by an end cap, and
- an area of a rib, of the plurality of ribs, being smaller than an area of a pole of the plurality of poles.
A rotor assembly comprising:
- a rotor including:
- a rotor core defining an end face;
- and
- a plurality of poles extending radially outwardly from the rotor core;
- and
- an end plate engaged to the end face,
- the end plate including:
- an annular body having a first axial end, a second axial end, and a thickness,
- the annular body defining an outer surface and a bore;
- and
- a plurality of ribs extending radially outwardly from the outer surface,
- the plurality of ribs being adapted to respectively abut with the plurality of poles, and
- the plurality of ribs and the plurality of poles being covered by an end cap.
A switched reluctance motor, comprising:
- a rotor including:
- a rotor core defining an end face;
- and
- a plurality of poles extending radially outwardly from the rotor core;
- and
- an end plate engaged to the end face,
- the end plate including:
- an annular body having a first axial end, a second axial end, and a thickness, the annular body defining an outer surface;
- and
- a plurality of ribs extending radially outwardly from the outer surface,
- wherein the plurality of ribs are respectively abutted with the plurality of poles, and
- wherein at least one of the plurality of ribs or the plurality of poles is covered by an end cap.
