Abstract
The invention relates to a magnetic pole piece for a permanent magnetic direct-drive wind power generator, and the magnetic pole piece is formed by horizontally laminating a plurality of magnetic pole stamped sheets, wherein the surface of each magnetic pole stamped sheet is provided with a plurality of positioning grooves with one side in a notch and the other side in a projection, and every two magnetic pole stamped sheets are buckled with each other through the notches and the projections of the positioning grooves. The plurality of positioning grooves are punched on the surface of each magnetic pole stamped sheet, so that every two adjacent magnetic pole stamped sheets in the vertical direction can be absolutely concentric with each other and tightly buckled with each other in the lamination process of the magnetic pole stamped sheets, and high parallelism and high verticality can be effectively ensured.
Description
Technical field
The present invention relates to the generator magnetic pole pole shoe and make the field, relate in particular to a kind of permanent magnet direct-driving aerogenerator and use the magnetic pole pole shoe.
Background technology
The magnetic pole pole shoe of permanent magnet is installed on the permanent-magnetic wind driven generator rotor,, generally builds up by the 0.5mm silicon steel sheet for reducing eddy current loss; The pole shoe of general prior art all adopts the silicon steel sheet surface with stick, and the silicon steel sheet bonding is the pole shoe piece of certain size length, for bonding is warmed to 200 ℃ for a neat pole shoe piece need pressurize; Because the fusing of high temperature stick has solation to go out, cause integral body to laminate back magnetic boots undulate, the depth of parallelism of pole shoe and perpendicularity can not be guaranteed; Increase the interstice of motor, influenced motor performance and useful life, when assembling, be prone to cause the permanent magnet surfaces damage; Can quicken the weightless speed of permanent magnet, and the length dimension of bonding is restricted, the pole shoe piece that seek out longer thickness is difficulty relatively; Its fixing tool is complicated and be difficult to control, can only be bonded to neat but the plurality of sections that thickness is long of comparison, but if will with plurality of sections pole shoe piece with pressing plate, be bolted to the permanent magnetism physical efficiency be free to slide; And the assurance permanent magnet surfaces is zinc-plated and the epoxy protective layer is not damaged, and the pole shoe on the insulation strip just must be bright and clean neat, promptly guarantees the high depth of parallelism and perpendicularity; When its technical process utmost point is taken a lot of work; And it is big to control difficulty, can not ensure the quality of products again, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiency of prior art, provide a kind of easy for installation, the permanent magnet direct-driving aerogenerator that the depth of parallelism and perpendicularity are high is used the magnetic pole pole shoe.
The present invention is for solving the problems of the technologies described above; Following technical scheme is provided: a kind of permanent magnet direct-driving aerogenerator is used the magnetic pole pole shoe; Laminate by some pole lamination levels and to constitute; It is characterized in that pole lamination surface punching press has several to be protruding location notch while being recess, two adjacent pole laminations fasten with protruding through the recess of location notch each other.
As of the present invention further preferred, the height of location notch is 0.5mm, because the pole lamination general thickness is 0.5mm, the location notch height is set to 0.5mm and had both guaranteed that pole lamination can not rupture the fine again assembly precision of having controlled because of undue the stretching.
Further preferred as the present invention, location notch quantity is preferably 6-8, and through 6-8 location notch is set, better controlled device precision effectively prevents again to offer too much location notch, causes the pole lamination distortion.
The present invention is through having several location notchs in pole lamination surface punching press, and to reach in the pole lamination lamination process, upper and lower two staple together definitely with one heart, effectively guaranteed the high depth of parallelism and perpendicularity.
