Abstract
The invention belongs to the technical field of traction machine devices, and particularly relates to an outer rotor permanent magnet synchronous traction machine which comprises a machine base, a stator iron core, a rotor magnetic yoke 10 and multiple permanent magnets 20 fixed to the inner side of the rotor magnetic yoke 10. The permanent magnets 20 are evenly distributed on the inner wall of the rotor magnetic yoke 10. A non-magnetic separation component 30 is arranged between every two permanent magnets 20. The non-magnetic separation components 30 are fixed to the inner wall of the rotor magnetic yoke and provided with limit components 31 preventing the permanent magnets 20 from disengaging. The outer rotor permanent magnet synchronous traction machine has the advantage that the permanent magnets are firmly fixed.
Description
Technical field
The invention belongs to traction machine mechanical equipment technical field, be specifically related to a kind of permanent magnet synchronous traction machine with outer rotor.
Background technology
The permanent magnet of elevator surface-mount type permanent magnet synchronous traction machine with outer rotor is generally a watt shape, and some pieces watts of its exterior arc surfaces of shape permanent magnet contact with rotor yoke internal circular surfaces and are adjacent to and fix, and usually have with under type:
First kind of way is both contacts after rotor inner surface or permanent magnet outer surface are coated with anaerobic adhesive, and after glue primary solidification, the bicomponent material of filling mutually containing epoxy resin at adjacent two pieces of permanent magnets is fixed.Shortcoming is: when glue and epoxy resin because of long-time running or sustaining temperature too high and aging after permanent magnet have the risk come off.
The second way is at permanent magnet inner arc surface processing counterbore, and processes the screwed hole of equal number at rotor yoke inner surface, then by the mode that screw is connected and fixed.Shortcoming is: easily cause face checking in permanent magnet surfaces perforate, if the excessive permanent magnet that also easily causes of sunk screw moment of torsion breaks when fastening permanent magnet.
For above two kinds of modes, Authorization Notice No. CN201320566266.3(publication date is: on April 23rd, 2014) the utility model relates to a kind of elevator outer rotor tractor permanent magnet fixing device, comprise rotor yoke and be arranged in the permanent magnet in rotor yoke, be provided with not magnetic conduction pressing plate, magnetic conduction pressing plate and rotor yoke are not fixed, magnetic conduction pressing plate is not evenly arranged between rotor yoke inwall adjacent permanent magnet, by not magnetic conduction pressing plate locking permanent magnet, reach the object of fixed permanent magnet, adopt not magnetic conduction pressing plate, elongated, two are only had to be fixed permanent magnet along its length, permanent magnet can not be limited slide axially, namely fix loosely.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of permanent magnet synchronous traction machine with outer rotor of permanent magnet fixation.
In order to realize the object of the invention, by the following technical solutions:
A kind of permanent magnet synchronous traction machine with outer rotor, comprise support, stator core, rotor yoke and be fixed on the multiple permanent magnets inside rotor yoke, it is characterized in that, described permanent magnet is evenly distributed in rotor yoke inwall, be provided with non-magnetic separating means between every two adjacent permanent magnets, described separating means is fixed on rotor yoke inwall and separating means is provided with the limiting component preventing permanent magnet from coming off.
As preferably, described separating means is the tetrahedron wide with permanent magnet spacing; Further preferably, described tetrahedron and rotor yoke inwall are threaded hole and through hole respectively, and described tetrahedron is connected through through hole and screwed hole with rotor yoke bolt.
As preferably, described limiting component is have two fins axially angled with permanent magnet at least, described fin respectively with the permanent magnet close contact being positioned at limiting component two ends; Further preferably, described fin is four; Or preferred further, described limiting component and described permanent magnet are linear contact lay.
As preferably, described rotor yoke inwall is provided with and prevents the limit of permanent magnet movement vertically to parts; Further preferably, described limit is the boss exceeding rotor yoke and permanent magnet contact-making surface to parts.
In sum, beneficial effect of the present invention is:
Traction machine of the present invention, comprise support, stator core, rotor yoke and be fixed on the multiple permanent magnets inside rotor yoke, permanent magnet is evenly distributed in rotor yoke inwall, be provided with separating means therebetween, separating means is provided with the limiting component that prevents permanent magnet from coming off and is fixed on rotor yoke inwall.Separated by permanent magnet by non-magnetic separating means, and in conjunction with the limiting component on separating means, separating means is fixed in rotor yoke simultaneously, prevents permanent magnet from coming off, so just can firmly fixed permanent magnet.
Further, separating means is the tetrahedron wide with permanent magnet spacing, and tetrahedron and rotor yoke are bolted, and uses tetrahedron, and it is wherein also with threaded hole, comparatively speaking, compare province's material, thus cost is lower, rotor yoke there is the through hole corresponding with tetrahedron upper screwed hole, just tetrahedron can be fixed in rotor yoke with bolt, because tetrahedron is with the limiting component preventing permanent magnet from coming off, so just permanent magnet and rotor yoke more firmly can be fixed; Further, tetrahedron has four limiting components, respectively with the permanent magnet close contact being positioned at fin two ends, is fixed, not only can clamp both sides permanent magnet, and can limit permanent magnet relative sliding vertically further by such.
Or further, limiting component and the axial angled fin of permanent magnet, with permanent magnet close contact; Face contact easily produces face, face comparatively speaking and slides, and when limiting component and permanent magnet are linear contact lay, opposite face contacts, and because lifting surface area is little, presses tighter, so the contact of linear contact lay opposite face, more firmly.
In order to further fixed permanent magnet, the present invention is provided with the limit that slides axially of restriction permanent magnet further to parts in rotor yoke, as being boss.
