Embodiment

[0029] The manufacturing steps of the outer rotor are as follows:

[0030] The magnetic steel ring and the steel bushing are pre-placed in the die-casting mold, and the rotor blank with the pillow block, the disc target-shaped convex ring and the fan fin is made by one-time die-casting through the aluminum die-casting machine, and then the disc After finishing turning, the target-shaped convex ring is made into a semi-finished product of a disc target-type compound inner rotor generator for standby use.

[0031] The magnetic steel patch is connected with the inner and outer circles of the disc target-shaped convex ring through the traditional inlay or pasting method to form a semi-finished double magnetic steel ring for use.

[0032] The manufacturing steps of the inner stator are as follows:

[0033] Each annular stator winding is composed of an annular iron core and a winding coil, wherein the inner circle and the outer circle of the annular iron core are provided with embe...

Abstract

The invention provides a disc-target type composite inner rotor generator, which is composed of an inner rotor and an outer stator. The inner rotor structure is composed of a prime mover power outputshaft, a shaft sleeve, a corrugated rotor disc and a protective mesh cover. The shaft sleeve is arranged in the middle of the corrugated rotor disc. Disc-target-shaped convex rings are arranged from the shaft sleeve to the edge of the corrugated rotor disc. The inner or outer circles of the disc-target-shaped convex rings are embedded with magnetic steel patches. Annular stator slots are formed between the disc-target-shaped convex rings. The prime mover power output shaft is arranged in the shaft sleeve. The shaft sleeve is arranged in the middle of a rotor base plate. The disc-target-shapedconvex rings are arranged vertically and in a layered manner on the surface of the rotor base plate to form a target shape. The disc-target type composite inner rotor generator of the invention has the beneficial effects as follows: the generator has the advantages of small volume, less material consumption, low weight, high power density, simple structure and easy processing; and one generator can replace a plurality of traditional generators and can output different currents and voltages at the same time.

Description

technical field [0001] The invention relates to the technical field of a brushless permanent magnet generator, in particular to a disc target type composite inner rotor generator. Background technique [0002] The traditional brushless permanent magnet generator has the disadvantages of heavy weight, many consumables, low current density, complex process and short service life in the process of production and use, which does not meet the requirements of the current era of energy saving and environmental protection. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned defects in the prior art, and provide a disc-target compound inner rotor generator with high power density, low consumption materials, and capable of simultaneously outputting different voltages to meet the multi-voltage requirements of special equipment. [0004] The object of the present invention is achieved according to the following scheme: the disc tar...
