Abstract
A rotor for a motor comprising a frame having a hub for connecting the rotor to a shaft and a perimeter portion for interacting with a stator of the motor to cause the rotor to rotate about an axis of rotation. The frame comprises legs extending from an outer portion of the frame towards the hub, each leg having an inner end at the hub and an outer end at the outer portion of the frame, the inner ends of a first plurality of legs being spaced from the inner ends of a second plurality of legs in a direction along the axis of rotation.

11. A method of manufacturing a rotor having a hub for connecting the rotor to a shaft, a perimeter portion for interacting with a motor stator to cause the rotor to rotate about an axis of rotation, and a frame between the hub and the perimeter portion, the method comprising the steps of:
-
stamping the frame from a sheet of metal to form legs, each leg extending outwardly towards the perimeter portion from an inner end, bending a first plurality of legs or a second plurality of legs or both from the frame so that inner ends of the first plurality of legs are axially spaced from inner ends of the second plurality of legs, and attaching the hub to the inner ends of the legs. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
