Aviation high-speed generator rotor structure

Abstract

The invention relates to an aviation high-speed generator rotor structure, which comprises a plurality of V-shaped slot wedges, a wing-shaped slot wedge, a winding, two hoop rings and a magnetic pole iron core. The aviation high-speed generator rotor structure is characterized in that the V-shaped slot wedges are changed into triangular slot wedges, a wedge block is arranged on a triangular cross beam, and the upper surface of the wing-shaped slot wedge is aligned with an excircle of the magnetic pole iron core. The aviation high-speed generator rotor structure has the advantages that the magnetic pole iron core, an excitation winding, the slot wedges and the like in a main generator rotor form a whole, the work intensity problem of products at a high rotating speed is solved, in addition, because the wing-shaped slot wedge and the surface of a rotor iron core approximately form a whole circle, the problem of surface friction loss of the high-rotating-speed rotor is reduced, and the efficiency of a generator is improved. The excitation winding on the rotor is tightly pressed by the slot wedges, so the offset of the winding during the rotation at a high rotating speed is reduced, the eccentric force reduction caused by unbalance quantity due to high-rotating-speed rotation is reduced, the load is low during the bearing rotation, and the work reliability of the generator is improved.

Description

technical field [0001] The invention belongs to aviation motor technology, in particular relates to a rotor structure of an aviation high-speed generator, and specifically relates to the application of meeting the strength requirements of the high-speed rotor of an aviation generator through the design of the rotor structure, and is suitable for the rotor structure of a high-speed aviation generator in a large passenger plane and a transport plane . Background technique [0002] Due to the particularity of the application field of aero-generator products, it is required that the aero-generator has the characteristics of light weight, high power density, and high reliability. High speed and good cooling methods are important ways for aero-generators to achieve high power-to-weight ratio. Aviation generators generally adopt a brushless three-stage winding structure, in which the main generator has a relatively large power and is a salient pole rotor. When the generator is run...
