Abstract
In order to effect a phase shift in a dual generator having a pair of rotor-supporting shafts, where the phase shift accommodates optimum performance characteristics in a device requiring minimal space therewithin, the phase shifting device includes a first gear associated with an end of one rotor-supporting shaft and a second gear associated with an end of the other rotor-supporting shaft. The ends of the rotor-supporting shafts and disposed in spaced adjacent relation and the first rotor-supporting shaft is drivingly interconnected to the second rotor-supporting shaft through the first and second gears which are drivingly interconnected by a planet gear. With the planet gear mounted on a motor, the motor can be locked to maintain a selected phase relationship between first and second generators defining the dual generator to directly transmit rotational movement of one of the rotor-supporting shafts to the other of the rotor-supporting shafts and the motor can be activated to cause a shift in the relative position of the one rotor-supporting shaft relative to the other rotor-supporting shaft to effect a phase shift between the first and second generators on command.
