A rotor assembly is disclosed herein that includes a diaphragm spring for retaining other components of the rotor assembly. The rotor assembly includes a rotor, a rotor carrier supporting the rotor, at least one spacer arranged on a radially inner side of the rotor, and the diaphragm spring. The diaphragm spring includes a first end formed on a radially outer end of the diaphragm spring that engages against the at least one spacer, and a second end formed on a radially inner end of the diaphragm spring that engages against the rotor carrier.

Self-retaining compressional diaphragm spring

A rotor for an electric motor includes an axis, a rotor carrier a plurality of rotor segments, a first end plate, a second end plate, and a spring element. The rotor carrier has a tubular portion with a cylindrical surface and a radial wall extending radially outwardly from the cylindrical surface. The plurality of rotor segments circumscribe the cylindrical surface. The first end plate is disposed at a first axial end of the plurality of rotor segments adjacent to the radial wall. The second end plate is disposed at a second axial end of the plurality of rotor segments. The spring element presses the first end plate, the plurality of rotor segments, and the second end plate against the radial wall. The spring element includes a ring portion and a plurality of segments extending axially from the ring portion.

Electric motor for hybrid module

A two-piece resolver clamping plate includes a first clamping segment and a second clamping segment. The first clamping segment includes a first arcuate clamping ring and exactly three arcuate clamping arms extending from the first arcuate clamping ring. The second clamping segment includes a second arcuate clamping ring and exactly two arcuate clamping arms extending from the second arcuate clamping ring. In an example embodiment, a first circumferential length of the first arcuate clamping ring is greater than a second circumferential length of the second arcuate clamping ring.
