The present invention is achieved in that the manufacture method of a kind of high speed alternating current generator rotor of the present invention is, produce a magnetic conduction end on each magnetic pole tooth of the star magnetic pole of alternator rotor, the magnetic pole tooth of magnetic conduction end and star magnetic pole is made as one, then fix a U-shaped every magnet on each magnetic conduction end, groove with the magnetic pole projection end of tubular magnetic pole fixes at U-shaped on magnet again, and fixes a magnet steel between the protruding fast and star magnetic pole of each magnetic pole of tubular magnetic pole.
The magnetic pole tooth of above-mentioned magnetic conduction end and star magnetic pole is that same material is made.
The of the present invention a kind of high speed alternating current generator rotor that builds according to the method described above is: this rotor comprises the star magnetic pole and the tubular magnetic pole that is provided with magnetic pole projection end that is provided with for installation rotor shaft for alternator axis hole, be provided with a magnetic conduction end that is integrated with magnetic pole tooth on each magnetic pole tooth of star magnetic pole, the top end face of magnetic conduction end is the arc surface shape, and the arc diameter of this arc surface is identical with the outside diameter of tubular magnetic pole; Fixing on each magnetic conduction end has a U-shaped every magnet, and the groove of tubular magnetic pole magnetic pole projection end fixes respectively at U-shaped on magnet, and fixing has a magnet steel between each magnetic pole projection of tubular magnetic pole and star magnetic pole.
Each magnetic conduction end is V-shape perpendicular to the cross sectional shape of star magnetic pole axial line.
Back-up ring after being connected by screw on the magnetic pole tooth rear end face of above-mentioned star magnetic pole, be connected by screw spill on the magnetic pole tooth front end face of star magnetic pole before back-up ring.
Before above-mentioned spill, the external cylindrical surface of back-up ring and magnetic pole projection and the U-shaped of tubular magnetic pole link together every magnet.
The front back-up ring of above-mentioned spill and rear back-up ring are the non-magnet_conductible material back-up ring.
The front back-up ring of above-mentioned spill and rear back-up ring preferably are non-magnetic stainless steel material back-up ring.
owing to having adopted technique scheme, the present invention has discarded the cup structure that in the prior art, alternator rotor adopts fully, rotor structure of the present invention has been cancelled the cup on conventional Sai Kexin+permanent magnetism mixed magnetic circuit alternator rotor, the present invention is under the prerequisite that does not change magnetic structure, the star magnetic pole of rotor former inside is extended (namely producing a magnetic conduction end that connects as one with magnetic pole tooth on each magnetic pole tooth of conventional spider magnetic pole) to rotor outer circle, and utilize the V character form structure of magnetic conduction end on the star magnetic pole, the star magnetic pole that links closely U-shaped outward is every magnet, simultaneously the star magnetic pole connects as one every magnet by back-up ring before spill and tubular magnetic pole and U-shaped again, thereby form one and connect overall structure closely.The present invention has changed alternator rotor general cup structure at present, and the present invention is not in the situation that change magnetic circuit, connect mechanically, make rotor organically become as a whole, the present invention has and has effectively improved the reliability of rotor when High Rotation Speed when greatly reducing making rotor difficulty.So, the present invention compared with prior art, that the present invention not only has advantages of is simple in structure, make easily, cost of manufacture is low, but also have advantages of that rotor mechanical intensity is high, long service life, functional reliability be high.
