Research Topics


The Marine Corps¦ next generation amphibious assault vehicle requires improved power generation capabilities due to increased power demand. Versatility (e.g., capability to drive two generators in parallel), high efficiency, and temperature independent voltage regulation are the goals of this development. Unique Mobility, Incorporated is ideally positioned to achieve these goals due to 15 years experience in applying small, lightweight, and efficient brushless permanent magnet (PM) motors and generators within vehicle applications. Unique is currently involved in many hybrid electric vehicle motors and generator programs, collaborating with Orbital Engine Corporation, Northrop Grumman, Houston Metro Transit Authority, US Department of Transportation, Deere & Company, and DARPA, as well as others. Within generator applications specifically, Unique¦s method of delivering constant voltage over a wide range of generator speeds and temperatures results in a minimum power electronics and delivers high efficiencies, usually exceeding 90% across a wide band. This experience is vital to improving the AAAV power generation system, where the Phase I goal will be to design an optimized generator with associated electronics. System efficiency in excess of 85% across the operating region is anticipated. A set of conceptual drawings along with prototype and production cost estimates will be included in the Phase I report.
