ABSTRACT:
Disclosed herein is a rotary pulse generator including an armature having a two-magnet assembly including spaced pole pieces defining a pair of spaced gaps, an armature plate including a charge core and charge coil mounted thereon, and a trigger core and trigger coil mounted thereon, said trigger core being separate from said charge core but located in proximity to said charge core so that, at a given armature speed, said trigger coil produces a repeating series of trigger pulses including a first major voltage pulse of one polarity and of a major magnitude closely followed by a second minor voltage pulse of opposite polarity and of a minor magnitude substantially less than the major magnitude, the repeating series of trigger pulses being produced in response to the two-magnet assembly sequentially rotating past the trigger core and the charge core. In a preferred embodiment, the rotary pulse generator includes a second two-magnet assembly, and the trigger core includes a thin edge extending radially outwardly so that a relatively sharp pulse is produced by the trigger coil each time one of the spaced gaps passes thereby.
