Patents by Inventor Maarten Jan Kamper

Maarten Jan Kamper has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9543815
    Abstract: The invention relates to an electrical energy conversion system (11) which is particularly suited for use in wind energy conversion systems. The system includes two magnetically separated permanent magnet machines (25, 27) linked by a freely rotating rotor (19) housing permanent magnets (39). The first machine is typically a synchronous generator, and the second an induction generator. The synchronous generator (25) has a stationary stator (21) which is connectable to an electrical system such as an electricity grid, and the induction generator (27) has a rotor (17) which is connectable to a mechanical drive system such as, for example, a wind turbine.

  • Publication number: 20120169063
    Abstract: A new configuration for a double-sided rotor, radial flux, air-cored, permanent magnet electric generator (1) is disclosed. The generator (1) includes two radially spaced apart rotor portions (33, 35) defining an air gap between them and each having a plurality of alternating polarity permanent magnets (41) arranged on their inner surfaces, mounted for rotation in the air gap. A modular stator (43) is positioned in the air gap and includes a base (45) having attachment formations (60) spaced apart about its surface and a plurality of individually moulded, polymeric resin stator modules (53). Each stator module (53) has complementary attachment formations (59) for attachment to the base (45) and includes at least one non-overlapping compact wound coil (61) which is embedded within the resin.
