An end ring for a rotor assembly in a vehicular electric machine, the rotor assembly having a first end and configured to rotate on a shaft, the end ring comprising:
- an annulus circumscribing the shaft and engaging the first end of the rotor assembly;
- and
- a sleeve coupled to the annulus and circumferentially coupled to the shaft.
An end ring of a type suitable for deployment in a vehicular electric machine having a rotor assembly configured to rotate with a hub assembly, the hub assembly including a sleeve portion about which the rotor assembly is circumscribed and including a flange having a first surface and extending radially outward from an end of the sleeve portion, the end ring comprising:
- an annular ring having a second surface configured to reside adjacent the first surface and having a third surface configured to reside adjacent an end of the rotor assembly;
- and
- a first protrusion extending from the second surface and configured to engage the first surface so as to separate the first surface from the second surface.
An end ring for a rotor assembly of the type deployable in a vehicular electric machine, the rotor assembly having an end and configured to rotate on a shaft and having a magnet coupled proximate the end, the end ring comprising:
- an annular ring circumscribing the shaft and engaging the end of the rotor assembly;
- a first tab coupled to an outer circumferential edge of the annular ring and configured to retain the magnet;
- and
- a sleeve portion integrally formed with the annular ring, and circumscribed about and coupled to the shaft.
