A rotary transformer having a rotor assembly mounted on a shaft and a plurality of associated cooperative stators rotatably mounted about the rotor assembly. The stators are angularly adjustable, relative to each other, about the axis of the shaft. Electrical power is delivered to one of the stators (the primary stator), which functions as a primary of the transformer. The remaining stators (secondary stators) function as a secondary of the transformer. The relative angular orientation between the secondary stators determines the magnitude of the output voltage from the secondary stators.

A rotary transformer comprising: a rotor assembly mounted on a shaft; a first stator, a second stator and a third stator disposed in operative relation about said rotor assembly, each said stator comprising a plurality of windings; said stators being relatively angularly adjustable with respect to each other about said shaft to provide a predetermined relative angular displacement of one stator with respect to said other stators, said windings of said first stator being adapted for connection to an AC supply as a transformer primary, said windings of said second stator and said third stator being in series communication and being adapted for connection to a load as said transformer secondary; said voltage supplied to said load being a function of the relative angular displacement among said first stator, said second stator and said third stator.
