Abstract
The invention provides a stator of a permanent magnetic suspension engine comprising a support ring made of non magnet-conductible material, a permanent-magnet arranged outside the support ring and a magnetic-conductible material sheet arranged inside the support ring, wherein, the permanent-magnet and the magnetic-conductible material sheet attract mutually. Abducent flanges are arranged on one or a plurality of cross sections of the support ring on the stator; the cross sections of the support ring take the shape of a round, or a rectangle or a polygon; and the support ring is divided into an upper part and a lower part which are symmetrical along the axial direction. The technical progress effects of the stator are shown as follows: the permanent-magnet and the magnetic-conductible material are closely combined together by utilizing the mutual attraction between the permanent-magnet and the magnetic-conductive material instead of other insertion manners, and the magnetic-conductible material and the permanent-magnet are assembled directly, so that the processing method is simplified; the low-cost magnetic-conductive material creates the same magnetic pole effect, the material cost is low, the utilization ratio is high, and the half of the permanent-magnet material can be saved; and the assembling manner of the permanent-magnet of the stator includes, but is not limited to, the suspension engine, and can be popularized to any electric motors.
Description
Technical field
The present invention relates to a kind of permanent magnet suspending motor stator, belong to the electromagnetic power technical field.
Background technology
In the prior art by the rare earth permanent-magnetic material neodymium iron boron as the pole material of motor or generator widespread usage, but because NdFeB material is relatively more expensive, in order to reduce cost, someone has proposed permanent magnetic material and permeability magnetic material technical scheme spaced apart, its mounting means is that permanent magnet and permeability magnetic material are plugged in the dovetail groove at interval at the uniform dovetail groove of shading ring inner ring.To improve the utilance of permanent magnet, reduce manufacturing cost.
Summary of the invention
The object of the present invention is to provide a kind of permanent magnet suspending motor stator, the improvement permanent magnet combines and set-up mode with permeability magnetic material, and assembling process is simplified more, reduces the integral production cost of stator.
Technical scheme of the present invention is achieved in that this permanent magnet suspending motor stator, it is characterized in that: support ring and the outer permanent magnet that is provided with of support ring that stator is made by non-magnet_conductible material are provided with the mutual adhesive of permeability magnetic material sheet and constitute in the support ring.
One or more cross section settings of described permanent magnet suspending motor stator support ring extend out flange.
The cross section of the support ring of described permanent magnet suspending motor stator is circle, rectangle or polygon.
The support ring of described permanent magnet suspending motor stator axially is divided into two parts up and down of symmetry and forms.
The support ring of described permanent magnet suspending motor stator radially is divided into a plurality of magnetic conductions unit, is connected and composed by the diamagnetic material connector.
Outer permanent magnet and the permeability magnetic material sheet of being provided with at interval of the support ring of described permanent magnet suspending motor stator, mutual adhesive.
The outer permanent magnet stack combinations that is provided with of the support ring of described permanent magnet suspending motor stator one or more layers.
Outer permanent magnet bar shaped, the trapezoidal or watt shape piece that is provided with of the stator support ring of described permanent magnet suspending motor.
The support ring of described permanent magnet suspending motor stator is outside equipped with magnetic shielding cover.
Technological progress effect of the present invention shows: owing to utilize permanent magnet and the mutual attracting mode of permeability magnetic material with permanent magnet and permeability magnetic material other the inserting mode of replacement that is closely linked, permeability magnetic material and permanent magnet are directly assembled, the processing mode simplification; Permeability magnetic material with cheapness produces same magnetic pole effect, and material cost reduces, and utilance improves can save 50% permanent magnet material, and the permanent magnet assembling mode of stator of the present invention includes but not limited to suspending motor, may extend to any motor.

Embodiment
The support ring 4,6 of permanent magnet suspending motor stator of the present invention shown in Fig. 1-4, the assembling mode of permanent magnet 2,3 and magnetic conduction bar 5,8, among the figure as can be seen, the embodiment of the present invention main innovate point is that permanent magnet 2,3 and permeability magnetic material sheet 5 directly are placed on the inside and outside wall of stator support ring 4,6, fixes by permanent magnet and the mutual adhesive of permeability magnetic material sheet.
Stator support ring the 4, the 6th is made by non-magnet_conductible material, and cross section is circular, rectangle or polygon, and for easy to assembly, the stator support ring is divided into axial symmetrical two parts 4,6 formation that is pulled together.The stator support ring radially is divided into a plurality of magnetic induction unit, and present embodiment provides 4 unit, leaves certain interval between each unit, and g connects and composes by the diamagnetic material connector.
Outer permanent magnet 2,3 stack combinations that are provided with of stator support ring one or more layers, provide the 2 stacked execution modes that add among the figure; Support ring outer wall permanent magnet is designed to bar shaped, trapezoidal or watt shape piece, and permanent magnet and permeability magnetic material sheet 8 are provided with adhesive mutually at interval.
Described stator support ring also is provided with magnetic shielding cover 1,7 outward, also is to be divided into the two parts symmetrical assembling.
Fig. 5,6,7 provides another embodiment of the present invention, i.e. one or more cross section settings at stator support ring 1,7 extend out flange 10,11, and present embodiment provides the flange that extends out that 4 cross sections are rectangle, is mainly used in main equipment.
