Abstract

Method of fabricating magnetomotive devices by encapsulating a unitary pole-shoe magnet group into a casting of nonmagnetic material. The pole-shoe portion of the group is formed of a plurality of integral, stacked ferromagnetic laminations, each having between the shoe portions an interconnecting web disposed radially inward of the outer surface of the pole-shoes. The magnetomotive device is cast so that the outer surfaces of the pole-shoe laminations are generally flush with the outer diameter of the casting. The interconnecting web portions are then removed so that the pole-shoes are magnetically separated. Alternatively, the disclosure is concerned with a pole-shoe magnet group for a flywheel magneto which is composed of a plurality of stacked ferromagnetic laminations embracing a permanent magnet. Each of the laminations has at least two pole-shoe portions interconnected by a web disposed radially inward of the outer surface of the pole-shoes whereby the web may be removed by a single drilling operation.
