Abstract
A molded rotor block, as well as other molded articles of manufacture, are made from a resin material selected from the group consisting of epoxy thermosets, polyester thermosets, phenolic, and melamine; and a reinforcement material selected from the group consisting of glass and mineral filler. The article of manufacture is adapted to withstand temperatures that range from about −40° C. to about 180° C.−40° C. and to withstand centrifugal loading at about 1500 RPM to about 4500 RPM while functioning as an insulator. The molding operation provides many advantages over CNC machining and other manufacturing methods.
Claims21
A molded rotor block for supporting an end winding extending outwardly from a slot end of a rotor of a power generator, the molded rotor block comprising:
- a molded body comprising integrally molded interior and exterior surface portions defining a shape for supporting the end winding extending outwardly from the slot end of the rotor of the power generator, said molded body comprising
- at least one thermoset resin material having a glass transition temperature above an operating temperature of the power generator, and
- at least one reinforcement material within said at least one thermoset resin material to provide stiffness and strength thereto.
A molded rotor block for supporting an end winding extending outwardly from a slot end of a rotor of a power generator, and comprising:
- a molded body comprising integrally molded interior and exterior surface portions defining a shape for supporting the end winding extending outwardly from the slot end of the rotor of the power generator, said molded body comprising
- at least one thermoset resin material having a glass transition temperature above an operating temperature of the power generator, and
- reinforcement fibers randomly embedded within said at least one thermoset resin material and comprising at least about 30% of a weight of said molded body.
A power generator comprising:
- a rotor having a plurality of rotor slots therein;
- a plurality of end windings extending outwardly from ends of the rotor slots;
- and
- at least one molded rotor block for supporting at least one of said end windings and comprising at least one molded body including integrally molded interior and exterior surface portions defining a shape for supporting the at least one end winding;
- said at least one molded body comprising at least one thermoset resin material having a glass transition temperature above an operating temperature of the power generator, and at least one reinforcement material within said at least one thermoset resin material to provide stiffness and strength thereto.
