Abstract
The utility model relates to a surface-mounted magnetic pole rotor of a direct-drive permanent magnet generator, which consists of a rotor bracket and magnetic steel, wherein a plurality of mounting grooves are arranged along the circumferential surface of the rotor bracket at equal intervals, and each mounting groove passes through the circumferential surface along the axial direction; a plurality of pieces of magnetic steel are available, and the widths of two sides of each piece of magnetic steel correspond to that of the mounting groove; and the pieces of magnetic steel are embedded into the mounting grooves on the surface of the rotor bracket and are firmly fixed by sunk screws. The surface-mounted magnetic pole rotor of the direct-drive permanent magnet generator has the advantages that compared with an embedded magnetic pole, as the rotor bracket is made of common steel, and a silicon-steel plate is not needed for overlapping and pressing, the surface-mounted magnetic pole rotor has simple technique, low cost and low magnetic leakage factor; compared with a surface-adhesive-type magnetic pole, as the mounting grooves on the rotor bracket can be used for fixing the magnetic steel, and a weftless bandage tape is not needed for binding, the surface-mounted magnetic pole rotor has simple technique; and meanwhile, the bottom surfaces of the pieces of magnetic steel are not needed to be processed into arc shapes, so that the pieces of magnetic steel are simple in processing. The surface-mounted magnetic pole rotor has novel and unique structure as well as simple installation and easy operation of a magnetic pole, and saves the cost.
Description
Technical field
The utility model relates to a kind of permanent magnet generator, permanent magnet motor surface-mount type pole wheel, is meant that especially a kind of internal rotor of direct-drive permanent-magnetism generator adopts the surface-mount type magnetic pole, is suitable for the megawatt-stage direct driving type aerogenerator and uses.
Background technology
Seen permanent magnet generator, permanent magnet motor magnetic pole mounting means mostly is embedded and surperficial two kinds of the formulas of pasting at present.The magnet steel of embedded magnetic pole embeds unshakable in one's determination inner, iron core need form with silicon steel plate stacking, fix then, so mounting structure is relatively complicated, magnet steel also is not easy to change simultaneously, has increased cost, weight, complex process, also have embedded magnet steel leakage field bigger, the use amount of identical specific power lower magnetic steel is big (as shown in Figure 1).The magnet steel that the formula magnetic pole is pasted on the surface utilizes special glue to stick on the rotor field spider surface, rotor surface carries out colligation with no latitude band more simultaneously, structure is simpler relatively, but technology is more complicated also, the also bad assurance of quality, and the binding face of the magnet steel of this magnetic pole and rotor field spider need do in the arc-shapedly, increased the difficulty of processing (as shown in Figure 2) of magnet steel.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is exactly magnet steel directly to be embedded in the mounting groove of being opened on the rotor field spider surface for the direct-drive permanent-magnetism generator provides a kind of surface-mount type pole wheel, carries out fastening with sunk screw, it is simple to operation that magnetic pole is installed, and saves cost.
The purpose of this utility model is achieved through the following technical solutions, rotor is made up of rotor field spider and magnet steel, equidistantly establish a plurality of mounting grooves along the rotor field spider circumferential surface, each mounting groove all runs through axial circumferential surface, magnet steel is a polylith, the both sides width of every block of magnet steel is all corresponding with mounting groove, the polylith magnet steel is embedded in the mounting groove on rotor field spider surface, and fastening with sunk screw.
The surface of described every block of magnet steel all radially is provided with at least two of countersunk head screws, and the concrete size of countersunk head screw can be decided according to the size shape of magnet steel.
The bottom land of the mounting groove on described rotor field spider surface is provided with the corresponding screw of countersunk head screw with magnet steel.
The set mounting groove of described rotor field spider circumferential surface can be 60～120.
All can inlay 5～15 blocks of magnet steel in described each mounting groove.
The thickness of the number of the mounting groove of rotor field spider circumferential surface and cell body size and magnet steel is all determined by the electromagnetic scheme of concrete generator.
Described rotor field spider is by being processed into after the ordinary steel welding.
Described magnet steel is Nd-Fe-B permanent magnet.
The utility model has the advantages that:
1, with respect to embedded magnetic pole, because rotor field spider is made by ordinary steel, do not need silicon steel plate stacking, technology is simple, and cost is low, and magnetic leakage factor is low simultaneously;
2, paste the formula magnetic pole with respect to the surface, because mounting groove and sunk screw on the rotor field spider have fixation to magnet steel, do not need not have the colligation of latitude band, technology is simple; The magnet steel bottom surface does not need to be processed into arc simultaneously, and magnet steel processing is simple.
3, novel structure uniqueness, magnetic pole is installed simple to operation, saves cost.
