Abstract
A rotary system includes a rotational component operable to rotate about an axis and having a base portion, a collar that extends axially outward from the base portion, and a flange that extends radially-outboard from the collar. A resolver is disposed axially between the base portion and the flange, wherein the base portion and the flange contact the resolver to limit axial deformation of the resolver.
Claims20
A rotary system, comprising:
- a rotational component operable to rotate about an axis and having a base portion, a collar that extends axially outward from the base portion, and a flange that extends radially-outboard from the collar;
- and
- a resolver disposed axially between the base portion and the flange, wherein the base portion and the flange contact the resolver to limit axial deformation of the resolver.
A method of assembling a resolver with a rotational component configured to rotate about an axis, comprising the steps of:
- disposing a resolver about a collar of the rotational component, such that the resolver contacts a base portion of the rotational component that extends radially outboard relative to the collar;
- and
- deforming the collar via forcible contact between the collar and a roller to form, from a portion of the collar, a flange that extends radially-outboard from an adjacent portion of the collar, wherein the resolver is disposed axially between the base portion and the flange to limit axial deformation of the resolver.
An electric motor assembly, comprising:
- a rotor configured to rotate about an axis;
- a rotor hub coupled with the rotor and having a central component, a portion of which is axially aligned with the rotor, and an outer component mounted to the central component at a position that is axially offset from the rotor, wherein the outer component comprises:
- a base portion;
- a collar that extends axially outward from the base portion;
- and
- a flange that extends radially-outboard from the collar distally from the base portion;
- and
- a resolver disposed axially between the base portion and the flange, wherein the base portion and the flange contact the resolver to limit axial deformation of the resolver.
