Abstract
A dual permanent magnet generator (10) is provided with a differential gear arrangement (20) comprising two ring gears (21, 26), two planetary gears (30, 31) and a carrier (32) which is splined to an input shaft (12) in the generator (10) so as to rotate the carrier (32) at the same speed as the input shaft (12) while allowing the input shaft (12) to shift axially. One of the ring gears (21) has a threaded connection (18, 38) with the input shaft (12). Consequently, as either the ring gear (21) or the ring gear (26) is slowed down through the application of a resistive load on small generators (22, 23 and 27, 28) associated with the respective ring gears (21, 26), the threaded connection (18, 38) will cause the input shaft (12) to move axially in one of two directions and, via lefthand and righthand spline connections (15, 16) between the input shaft (12) and main rotors (13, 13'), cam the rotors (13, 13') to shift into and out of phase with respect to each other.
