APS will expand on available and evolving analytical/numerical tools to address design and performance parameters for Permanent Magnet couplings and gears. APS has developed complex modeling tools for designing and assessing current permanent magnet (PM) motors under ONR sponsorship. These tools have been transitioned to magnetic gear applications, as techniques for addressing flux densities, material modeling, torque calculation, electromagnetic losses and noise performance are comparable for both PM motor and PM gear set machines. Additionally, APS has leveraged available FEA tools to address design nuances that influence the performance of PM gear sets, most specific to the torque density of the device. APS will address not only combinations of mutually-influential design parameters, but also multi-physics relationships including magneto-thermal and magneto-acoustic concerns.
