Description
Technical field
The present invention relates to the fixture of permanent magnet on magneto, be specially a kind of magnetic pole box with positioning boss.
Background technology
Wind power generation, as a kind of clean reproducible energy, due to its environmentally safe and its good economic benefit, is more and more subject to the attention of countries in the world.In numerous wind-driven generator types, permanent-magnetic wind driven generator, because of the feature that it is lightweight, volume is little, cost is low, efficiency is high, maintenance is little, becomes the representative of wind-driven generator of new generation.Magnetic pole box is the critical component on magneto, has well fixing protective effect to permanent magnet.Existing magnetic pole box is generally laminated by dove-tail form pole lamination and is welded, and as shown in Figure 4, dove-tail form pole lamination is complex-shaped for dove-tail form pole lamination, makes mould, the complex process of pole lamination.During magnetic pole box assembling, the dovetail groove specification in yoke is general all comparatively large, and when magnetic pole box is placed in the dovetail groove in yoke, need to increase voussoir to each magnetic pole box and fix, cause assembling to waste time and energy, production efficiency is low.And the magnetic pole box radial dimension of this structure is comparatively large, curvature stress can be caused excessive, there is unsafe factor in high-speed permanent magnet motor.
Summary of the invention
The present invention, in order to solve the problem of existing magnetic pole box unreasonable structure, provides a kind of magnetic pole box with positioning boss.
The present invention adopts following technical scheme to realize: the magnetic pole box with positioning boss, some first pole lamination identical by shape and some second pole laminations are overrided to form, first pole lamination and the second pole lamination have permanent magnet installing hole all accordingly and be positioned at the fixed lever installing hole below permanent magnet installing hole, the limit that second pole lamination contacts with yoke also has bolt penetration hole, bolt penetration hole is communicated with fixed lever installing hole, namely the magnetic pole box laminated there is permanent magnet installing hole, be positioned at fixed lever installing hole below permanent magnet installing hole and be positioned on the face that contacts with yoke and the bolt penetration hole communicated with fixed lever installing hole, the part of bolt penetration hole is wherein had to be built up by the second pole lamination, remainder is built up by the first pole lamination, the fixed lever being processed with bolt hole is also placed with in fixed lever installing hole, bolt hole position on fixed lever and the correspondence of the bolt penetration hole position in magnetic pole box.By bolt and the fixed lever inserting magnetic pole box, magnetic pole box can be fixed in yoke, and such pole lamination simple shape, the mould, the technique that make pole lamination are also simple.The magnetic pole box radial dimension built up by such pole lamination is little, is applicable to high-speed permanent magnet motor.
The above-mentioned magnetic pole box with positioning boss, first pole lamination is extended with location lug accordingly with the Bian Shangjun contacted with yoke on the second pole lamination, namely face magnetic pole box contacted with yoke there is positioning boss, positioning boss can insert the guide-localization groove that yoke coordinates with it, facilitate the installation of magnetic pole box, also make the circumference of magnetic pole box locate more accurate.
The above-mentioned magnetic pole box with positioning boss, first pole lamination and the second pole lamination scribble viscous coating, laminated by pole lamination that to weld the magnetic pole box eddy current loss that formed large, if toughness coating on pole lamination, magnetic pole box eddy current loss through the formation of heat-insulating pressurizing technique after laminating is little, and also need not weld.
The above-mentioned magnetic pole box with positioning boss, one end of described fixed lever has breach, and a part for the fixed lever of indentation, there stretches out fixed lever installing hole; When the magneto of relatively high power assembles magnetic pole box, multiple magnetic pole box can be close to along rotor axial and be fixed in yoke, the indentation, there of the fixed lever on adjacent pole box fixed lever installing hole coordinates, and the pole lamination that adjacent pole box can be prevented to be close to place flies out in rotor high-speed rotary course.
The invention enables magnetic pole box to laminate operation more simple, shorten process cycle, save time 10%; Particularly when magnetic pole box is assembled, the positioning boss in magnetic pole box coordinates with the location notch in yoke, adds assembly precision while saving guide-localization frock, and eliminates the voussoir of assembling, simplifies assembling process, saves frock cost 12%; Whole magnetic pole box radial dimension is less simultaneously, can meet high-speed permanent magnet motor design needs, apply more extensive.
