Research Institution
Many systems have mechanical couplings and gears that require lubrication and cooling, produce vibration and noise, experience wear, and are unreliable. Magnetic couplings and gears are an emerging technology that can provide superior characteristics for some applications. Although commercial magnetic couplings exist and prototype magnetic gears have been demonstrated, concerns with torque density, dynamic operation, and cost have limited widespread implementation to date. In response, we propose to design, fabricate, and test an advanced prototype coupling and gear that are optimized for specific military applications. This work will demonstrate the superior operational characteristics of these devices in military environments. During Phase I, we will evaluate coupling and gear concepts, conduct design-trade assessments, develop optimized preliminary designs, and estimate production costs. We will then fabricate and test a prototype magnetic coupling and a prototype magnetic gear during Phase II.
