MPCO-SMOS series … A magnetizer (10) for a rotor (12) of an electrical machine is provided. The invention is a permanent magnet rotor assembly comprised of a radially oriented cobalt alloy ring magnet pressed and sintered directly on the rotor shaft or hub and characterized by a barrier of high temperature inert material disposed between the magnet and the soft ferromagnetic hub'or shaft. Within the rotor assembly, the rotor hub, the shaft, and the permanent magnets can independently or collectively be modified to have a reduced mass. This new hybrid magnet now has a different function with the permanent magnets on the rotor assembly. A permanent magnet assembly (22) for assembly in large permanent magnet (PM) motors and generators includes a two-piece carrier (23, 24) that can be slid into a slot (13) in the rotor (10) and then secured in place using a set screw (37). Upon rotation of the rotor assembly, there are thus formed three separate sources of continuous alternating current, the first source having leads 81, 82, the second source havingleads 91, 92 and the third source having leads 101, 102.
