ABSTRACT:
Rotor of a magnetomotive device has a discrete permanent magnetic and a ferromagnetic core disposed within an injection molded, synthetic plastic body in the form of a flywheel. The core is of integral, laminar construction and includes hub and counterweight portions and a pair of radially extending, circumferentially spaced arm portions. At their outer ends, the arm portions terminate in pole shoes with opposed, undercut edges to retain the discrete permanent magnet therebetween. Each of the arm portions has a laterally extending shoulder portion and, at their inner ends, connect to the hub by narrow neck or stem portions which are resiliently flexible. From the center of rotation of the rotor, the stem portions are each disposed along a given radius. Each of the arm portions of the core is characterized by a configuration and distribution of mass so that its center of gravity is located outward of the given radius whereby centrifugal force generated by high speed rotation of the rotor exerts opposing, inwardly directed forces on the arm portions for clamping the magnet therebetween.
