SYNCHRONOUS NON-CONTACT GENERATOR Russian patent published in 2013 - IPC H02K21/14 H02P9/40 

FIELD: electricity.

SUBSTANCE: synchronous non-contact generator comprises a rotor (1) with permanent magnets and an anchor (2) with an m-phase working (3) and an m-phase additional (5) windings connected according to the delta circuit. Identical phase areas of working and additional windings are combined, and their turns are arranged in common slots of the anchor. The generator (1) rotor is rotated by the shaft of the primary motor, proportionally to speed of which frequency and voltage vary at the generator's output. Dependence of output voltage of the generator at the output of the working winding reduces as a result of magnetising action of anchor reaction flow generated by an additional winding (4). The additional factor that stabilises output voltage of the working winding (3) is also an electromotive force of mutual induction, generated by an additional winding (4) with increased speed of primary motor or load current. Therefore, the additional winding provides for internal negative feedback by generator voltage.

EFFECT: reduced dependence of output voltage on speed of rotation and load current, which expands its functional capabilities and increases its reliability due to reduced number of outputs from a generator anchor.
