Magnetic rotation transmitting device, hermetic stirring unit, and electric furnace

In order to provide a magnetic rotation transmitting device capable of obtaining a large transmitting torque without using a large-sized permanent magnet, in an axial-type magnetic rotation transmitting device, which includes a driving rotation body having one or plural magnetic line(s) in which plural first magnets (10A) are disposed in a circumferential direction on a first disk (11A) at almost equal intervals, a drive source rotationally driving a drive shaft of the driving rotation body, and a driven rotation body having one or plural magnet line(s) in which second magnets (20A) of the same number as the first magnets (10A) are disposed in the circumferential direction on a second disk (21A) at almost equal intervals, symmetrically disposed to, and magnetically coupled with the driving rotation body with a magnetic coupling gap and, which utilizes a magnetic operation and which allows the driven rotation body to rotate by rotationally driving the drive shaft by means of the drive source, the first magnet (10A) has a N-magnetic pole portion and a S-magnetic pole portion, and an extended surface of a boundary surface between the N-magnetic pole portion and the S-magnetic pole portion approximately overlaps with a driving center line as being a rotation center line of the driving rotation body, the second magnet (20A) has the N-magnetic pole portion and the S-magnetic pole portion, and the extended surface of the boundary surface between the N-magnetic pole portion and the S-magnetic pole portion approximately overlaps with a driven center line as being the rotation center line of the driven rotation body, adjacent and facing surfaces of the first magnets (10A) adjacent to each other on the first disk (11A) are disposed so that magnetic pole faces having the same polarity make pairs, and adjacent and facing surfaces of the second magnets (20A) adjacent to each other on the second disk (21A) are disposed so that the magnetic pole faces having the same polarity make pairs.

Magnetic advanced gas-turbine transmission with radial aero-segmented nanomagnetic-drive (MAGTRAN)

An electrical machine apparatus having magnetic gearing embedded therein includes a moveable rotor having a first magnetic field associated therewith, a stator configured with a plurality of stationary stator windings therein, and a magnetic flux modulator interposed between the moveable rotor and the stator windings. The magnetic flux modulator is configured to transmit torque between the first magnetic field associated with the moveable rotor and a second magnetic field through a movable stator, through a plurality of magnetic flux gates arranged axially in the modulator with the field excited by, and controlled by, eddy currents normal to the field through the plurality of stationary stator magnets governed by the position of the modulator rotating in reference to the rotating (at different speeds, hence flux paths) stator and rotor and their magnetic field poles, than the speed of the modulator and its interfering referenced field poles, with the eddy currents existing flux gate arrays with open or closing sequencing governing rotational speeds of the movable rotor, and enabling magnetic gear ratios, in respect to the driving movable stator, intermediate magnetic flux modulator, methods of a continuously variable, high torque, aero gas turbine transmission which allows for complete segmentation of turbomachinary stages (in respect to the bypass fan, compressor and power of the aero gas turbine.
