| Project Detail |
Advanced Magnet Lab (AML) is developing a reliable, contact-free current transfer mechanism from a stationary to a rotating electrode to allow direct current (DC) electrical machines, motors, and generators to achieve unprecedented power and torque density. This technology, a reimagining of the first electric "homopolar" motor invented by Michael Faraday, would provide current transfer without the need for the costly sliding contacts, brushes, and liquids that have limited DC electrical engine efficiency and lifetime. AMLs contact-free current transfer would achieve 99% efficiency in DC electrical motors with 5-10 times the power and torque densities available in existing DC technologies |
