Abstract:
A method for making a rotor for a permanent magnet motor, the method, in at least certain aspects, including connecting a series of a plurality of guides to a hollow rotor body, the guides spaced-apart and extending longitudinally of the rotor body, the rotor body being generally cylindrical with an interior surface, applying a plurality of magnets to the interior surface of the rotor body, and emplacing a shunt structure over the plurality of magnets to inhibit inter-magnet action during rotor assembly.
