Abstract
A rotor for an electric machine includes pairs of magnets with a bridge region therebetween.

A clip may be installed in the openings and a bonding material may fill the remainder of the bridge region.
Claims5
A rotor for an electric machine comprising:
- a plurality of magnets;
- a core comprised of stacked laminations that define pockets, between a hub portion and a pole portion, for receiving pairs of magnets, and that define a first projection extending from the pole portion and a second projection extending from the hub portion, the first projection and the second projection disposed in a bridge region between magnets that comprise the pairs, and the first projection and the second projection each defining a bar extending from the pole portion and the hub portion, respectively, and a cross-bar at a distal end to form a T-shape;
- a bonding material disposed in the pockets;
- and
- a clip disposed within the pockets, embedded in the bonding material, and cooperating with the first projection, the second projection, and the bonding material to provide a structural connection between the hub portion and pole portion.
