A low loss synchronous magnetic drive system for high pressure, high horsepower applications is disclosed. A carrier member driven by a drive motor carries spaced apart sets of drive magnets with the magnets of one set being of opposite polarity to the longitudinally aligned magnets of the other set. An output shaft carrying driven magnets oriented similarly to the drive magnets is also provided. A metallic hyperbaric barrier separates the drive and driven magnets. The barrier includes an outer cylinder having circumferentially spaced, radially directed, narrow slots extending therealong. Within the cylinder is a plurality of axially adjacent annular laminations insulated from each other. During operation the combination of the slotted cylinder, the laminations and the magnet arrangement keeps eddy currents generated in the barrier at a minimum, ensuring a high efficiency drive operable at speeds and pressures heretofore unattainable.
