Abstract
A cage carrying two axially adjustable conductors is mounted on one shaft and a rotor is mounted on a second coaxial shaft to occupy a position between the conductors. Permanent magnets on the rotor have poles spaced by air gaps from the conductors. The air gaps are adjusted by sliding the conductors toward and away from one another along slide members on the cage by use of adjustment units engaging the conductor rotors. Alternatively, the conductors can be mounted on the rotor, and the magnets can be adjustably mounted on the cage.
