Application of Correlated Magnetics to Magnetic Torque Transfer Devices

During the Phase I project, 40% improvements in magnetic shear force and 200 to 500% increases in magnetic coupling torque-density were demonstrated by applying the Correlated Magnetics Research"s (CMR) domain engineering and magnetization technologies to commercially available materials. The Phase II builds on this previous work in four important ways. 1) CMR will seek greater shear force improvements from domain optimization and creating low-tensile force magnetic structures that retain shear force capabilities, 2) CMR will scale its novel magnetization machines to support volume production for industrial devices, 3) CMR will work with at least one magnetic coupling company to develop a commercialization plan that identifies the best first coupling product, subsequent coupling product opportunities and subsequent opportunities related to magnetic gears, and 4) CMR, again with at least one industry partner, will design, build and test a fully functional magnetic coupling to a TRL 5. The improvements in magnetic couplings developed and demonstrated during the proposed work can be applied directly to many magnetic gear architectures during concurrent or subsequent research and development efforts. Magnetic couplings are 1-to-1 magnetic gears and represent the largest number of applications and highest volume of individual units of any magnetic gear market segment.
