Abstract
Encapsulation of a permanent magnet rotor is achieved by applying a glass roving material to spaces in the rotor structure, applying a veil cloth around the outer surface of the rotor, mounting a vacuum bag with vacuum ports around the outer surface of the rotor, removing vent plugs from the end walls of the rotor and screws from an inner ring of the rotor and replacing them with vacuum ports and applying a vacuum to the vacuum ports. After air has been removed from the rotor, an encapsulating resin is applied to some of the ports to introduce resin into the interior of the rotor. After curing of the resin the vacuum bag is removed and the outer surface of the rotor is machined to the desired outer dimension of the rotor.
