Under Phase I, tradeoff design studies will be completed to size the system and assess the configuration that will yield the highest power and energy densities while also having minimal maintenance requirements and shock tolerance. Under Phase II, a technology demonstrator will be designed, built and tested. The overall goal is to demonstrate and verify the power density gains and reduced footprint possible through effectively integrating the generator, bearing and flywheel components. MiTi's proposed solution is a high-speed flywheel energy storage module that uses our unique combination of shock tolerant and low loss magnetic bearings and high performance permanent magnet brushless DC motor/generator. Both 35 and 80 kW/60,000 rpm motor/generators that have already been developed and tested by MiTi will form the core design of the composite flywheel system. Flywheel speeds as high as 100,000 rpm will be examined. A subcomponent bearing test will be completed as a part of the Phase I effort. Benefits: Besides UPS and ride through power systems, bottoming cycle turbogenerator systems, subsystem motor/generator and component bearing system technologies will all benefit from this effort. Licensing is an essential element of our strategy to ensure transition of the technology to DOD systems since the existing suppliers have the expertise, certifications and infrastructure necessary to produce and deliver shipboard worthy systems. Additionally, since MiTi is developing high-speed motor driven oil-free compressors, blowers as well as renewable and waste energy turbogenerators for industrial and automotive applications, we have an opportunity to transition the technology to our own products. In the arena of industrial products where annual volumes will be more consistent with aerospace quantities (i.e., on the order of 300-500 units per year), MiTi is pursuing strategic alliances with several different manufacturers. Under strategic alliances, MiTi would produce the drive motor or turbogenerator subsystem and the necessary bearing mechanical components. Besides flywheel generators, compressors, blowers and turbogenerators drive motors for high speed grinding spindles are possible. Return
