The top of support.Mainly there is two ways at present：1st, first kind of way is connected by middle fixed base plate, and middle fixing plate is bored
There are 4 screwed holes for being fastenedly connected with motor bed-plate, what is had is also drilled with 2 pin-and-holes that can be accurately positioned, and centre is fixed
Processing and drum brake electric magnet external diameter one section of circular arc of identical are also needed on plate, is machined with the middle part of circular arc and drum brake
The through hole that electric magnet middle part is connected, via count be 4, by bolt be distributed in drum brake electric magnet it is cylindrical on
Screwed hole connection positioning.2nd, the second way is that using less middle fixing plate, one end of fixed plate is plane, another plane
On be machined with and concave arc in one section of drum brake electric magnet external diameter identical, 4 through holes, motor machine are drilled with fixed plate
Seat processing one and middle fixing plate plane sizes identical groove, groove baseplane is drilled with 4 through holes.First by fixed plate during installation
Embedded motor bed-plate, is connected positioning with the cylindrical upper screwed hole of drum brake electric magnet is distributed in by bolt.Above two
The through hole pitch-row for fixing brake electric magnet that mode is processed on middle fixing plate is respectively less than 50 ㎜, brake electric magnet
Easily loosen.
The content of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of permanent magnet and drum brake electric magnet fix tightly
Solid permanent magnet synchronous traction machine with outer rotor.
To achieve these goals, the present invention is employed the following technical solutions：
A kind of permanent magnet synchronous traction machine with outer rotor, including drum brake, motor bed-plate, stator core, rotor rim
With the multiple permanent magnets being fixed on the inside of rotor rim,
The drum brake is provided with drum brake electric magnet, and the drum brake electric magnet is located at motor bed-plate
Top, be machined with the top of motor bed-plate and drum brake electric magnet external diameter two interior concaved circular cambered surfaces of identical, it is described in
Concaved circular cambered surface is fixedly connected with drum brake electric magnet；
The permanent magnet is evenly distributed in rotor rim inwall, per be provided between two adjacent permanent magnets it is non-magnetic every
Part is opened, the separating means are fixed on rotor rim inwall and separating means are provided with the limiting section for preventing permanent magnet from coming off
Part.
The frame motor support is connected by step with stator core.
Preferably, the separating means are the tetrahedron wide with permanent magnet spacing, the tetrahedron and rotor
Yoke inwall is respectively provided with screwed hole and through hole, and the tetrahedron passes through screwed hole and through hole to connect with bolt with rotor rim inwall
Connect.
Preferably, the limiting component is four fins with two with the tight linear contact lay of permanent magnet, the fin is solid
Surely be arranged on tetrahedron, and with four sides body by integral forming.
Preferably, the rotor rim inwall is provided with the limit for preventing permanent magnet to be axially moveable to part.
Preferably, the step is made up of 6 convex surfaces and 6 concave surfaces, it is distributed in uniform intervals, the step is fixed on
On motor bed-plate.
The invention has the beneficial effects as follows：
1st, a kind of permanent magnet synchronous traction machine with outer rotor of the present invention, drum brake are located at the upper of motor bed-plate
Side, is machined with the top of motor bed-plate and concaved circular cambered surface in drum brake electric magnet external diameter identical, by interior concaved circular cambered surface
Coordinate with drum brake electric magnet and contact, accurate positioning, and be not required to middle fixing plate and can guarantee that drum brake electromagnetism
The ferrum device reliably fixed with motor bed-plate.
2nd, permanent magnet is evenly distributed in rotor rim inwall, is provided with separating means therebetween, and separating means are provided with to be prevented
Limiting component that permanent magnet comes off simultaneously is fixed on rotor rim inwall.Permanent magnet is separated by non-magnetic separating means, and
With reference to the limiting component on separating means, while separating means are fixed in rotor rim, prevent permanent magnet from coming off, so just may be used
So that permanent magnet is firmly fixed.
Further, separating means are the tetrahedron wide with permanent magnet spacing, and tetrahedron is with rotor rim inwall by spiral shell
Tether and connect, it is using tetrahedron and wherein also with threaded hole, comparatively, compare province's material, so as to cost is relatively low, rotor rim
On have through hole corresponding with tetrahedron upper screwed hole, just tetrahedron can be fixed in rotor rim with bolt, due to tetrahedron
With the limiting component for preventing permanent magnet from coming off, so just permanent magnet and rotor rim can be more firmly fixed；Further,
Tetrahedron has four limiting components, is in close contact with the permanent magnet positioned at fin two ends respectively, by such fixation, not only may be used
Both sides permanent magnet is clamped, and can further limit permanent magnet relative slip vertically.
Or further, limiting component and the axially angled fin of permanent magnet are in close contact with permanent magnet；Face contacts
Comparatively the slip of face face is also easy to produce, when limiting component is in linear contact lay with permanent magnet, for opposite face contact, due to stress surface
Product is little, presses tighter, so for the contact of linear contact lay opposite face, more firmly.3rd, further, motor bed-plate of the present invention with it is fixed
Sub- iron core is connected by step, and by 6 convex surfaces and 6 concave surface uniform intervals distributions, stator core endoporus shrinks step, by original
Circular hole become approximate positive 12 side shape hole, be significantly greatly increased and prevented the ability that rotates on support of stator core, by the party
Case suitably increases the magnitude of interference that stator core endoporus is coordinated with motor bed-plate step, increases nip, further increases resistance
The probability that only stator core is rotated on support.
Further, in order to preferably allow stator core preferably to be fixed with support, the convex surface of step is machined surface, in order to
Process cost is saved more broadly, the concave surface of step is non-processing face.
