Abstract: A system for transferring mechanical torque variably between a plurality of rotating machines in a turbofan engine. Two devices are used, where the first device relies upon magnetic properties of a planetary magnetic gearbox to couple the magnetic machines. The second device is used to variably control the torque transfer between the magnetic machines. The system couples rotating shafts rotating at differing speeds within a turbofan engine for controllably transferring power. To transfer power in the system, a fixed gear ratio is obtained by coupling the relatively high- and low-speed engine shafts to an epicyclic magnetic gearbox.

The segments can have a selectively predetermined length, and are cut from a strand traveling into a machine at a feed speed. The machine includes a moveable cutter that accelerates to the feed speed of the strand in a direction along the strand. A length of strand extending past the cutter is determined at real time based on a signal from a proximity sensor. When the speed of the cutter closely matches the feed speed and when the length of the strand extending past the cutter is determined to be equal to the predetermined length, the cutter is commanded to cut the strand and return to a home position.
