Abstract
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.
