A permanent magnet rotor has a stack of disk laminations, each lamination having a plurality of pole piece sections connected to one another by circumferential bridges situated on the disk periphery. Radial ligaments connect the core portion of the disk to the bridges. The core portion and pole piece sections define the radial thickness of the magnet slots. Magnets are situated in the magnet slots and the bridge positions of the rotor are inwardly deformed, causing the radial ligaments to collapse, thereby holding the magnets in their respective slots.
