AXIAL CONTACTLESS DIRECT CURRENT GENERATOR Russian patent published in 2010 - IPC H02K21/24 H02K21/12 H02K29/00 H02K1/06 

FIELD: electricity.

SUBSTANCE: proposed axial contactless direct current generator contains a housing, a subexciter, an exciter and the main generator. The permanent magnets of the subexciter inductor and the magnetic conductors in the grooves whereof the windings of the subexciter, the exciter and the main generator are laid are designed to be axial. The side axial magnetic conductors are rigidly mounted inside the housing while the permanent magnets of the subexciter inductor and the inner axial magnetic conductor are rigidly mounted on a shaft so that to be capable of rotation relative to the side axial magnetic conductors. The permanent magnets of the subexciter inductor are mounted on the butt-end of one side axial magnetic conductor while the inner axial magnetic conductor is mounted between the side axial magnetic conductors. The inner axial magnetic conductor and the side axial magnetic conductor on the butt-end whereof the permanent magnets of the subexciter inductor are mounted have two active but-end surfaces with grooves while the other side axial magnetic conductor has one active but-end surface with grooves. Laid in the grooves of the side axial magnetic conductor with two active but-end surfaces on the side of the permanent magnets of the subexciter inductor is a single-phase exciter excitation winding connected to the subexciter operational winding via a multi-phase double half-period rectifier. Laid in the grooves of the inner axial magnetic conductor on the side of the exciter excitation winding is a multi-phase exciter operational winding while on the other side a single-phase main generator excitation winding is laid connected to the exciter operational winding via the multi-phase double half-period rectifier. Laid in the grooves of the side axial magnetic conductor with a single active but-end surface is a multi-phase main generator excitation winding connected to the multi-phase rectifier.

EFFECT: generator manufacture technology simplification and generated voltage quality improvement.
