A FLYWHEEL

摘要

The invention relates to an apparatus and method for constructing a magnetic gear coupling for transmitting torque from a flywheel to a driveshaft, the coupling employing permanent magnet arrays and magnetic flux coupling elements therebetween, and at least one of the arrays and coupling elements being circumferentially staggered or spread, so as to avoid complete alignment of the arrays and elements, and thereby mitigate torque coupling capability variations.
