Latest Patents

Among McMullen's noteworthy inventions is a patent for a **permanent magnet rotor construction**. This design includes a rotor with a centrally located permanent magnet section that has aligned magnet segments and features a central hole running through its length. A thin rod of magnetic steel is placed in this central hole to provide support for the permanent magnets internally. This design is enhanced by threaded sections at both ends for attachment to supportive end stubs, while a high-strength steel sleeve fits over the magnets and end stubs, ensuring a robust mechanical connection. The structure is designed to keep the end stubs and central magnet concentric during processing and to prevent relative motion between the rotor components.

Another significant patent by McMullen is for an **energy storage flywheel** that incorporates minimum power magnetic bearings along with a motor/generator. This optimized flywheel energy storage system features high efficiency magnetic bearings and a high-speed permanent magnet motor/generator. The flywheel is made from a high-strength steel wheel, which allows for effective kinetic energy storage and a cost-effective construction for the energy storage rotor.
