Abstract
The utility model provides a permanent magnet suspension engine stator, which comprises a supporting ring made of non-magnetically-conductive material, a permanent magnet arranged outside the supporting ring, and a magnetically conductive material sheet arranged in the supporting ring, wherein the supporting ring, the permanent magnet and the magnetically conductive material sheet are mutually pulled in. Outwards expanding flanges are arranged on one or a plurality of cross sections of the supporting ring of the stator; the cross sections of the supporting ring are circular, rectangular or polygonal; and the supporting ring is divided into an upper part and a lower part which are symmetrical in the axial direction. The utility model has the following technological advanced effects: because the permanent magnet and the magnetically conductive material are closely combined by pulling in each other to replace other insertion manners, the magnetically conductive material and the permanent magnet are directly assembled, and the processing manner is simplified; and the same magnet pole effect is generated by the cheap magnetically conductive material, so that the material cost is reduced, the utilization rate is improved, and the permanent magnet material can be saved by 50%. The assembly manner of the permanent magnet of the stator is applicable to but not limited to suspension engines, and can be popularized to any electric motor.
Description
Technical field
The utility model relates to a kind of permanent magnet suspending motor stator, belongs to the electromagnetic power technical field.
Background technology
Existing 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, to improve the utilance of permanent magnet, reduce manufacturing cost.The mounting means of permanent magnet has the people to propose at the uniform dovetail groove of shading ring inner ring, and permanent magnet and permeability magnetic material are plugged in the dovetail groove at interval.
Summary of the invention
The purpose of this utility model is to provide a kind of permanent magnet suspending motor stator, improves the combination and the set-up mode of permanent magnet and permeability magnetic material, and production process is further simplified, and reduces the integral production cost of stator.
The technical solution of the utility model 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 the support ring of described permanent magnet suspending motor stator 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 support ring of described permanent magnet suspending motor stator.
The support ring of described permanent magnet suspending motor stator is outside equipped with magnetic shielding cover.
Technological progress effect of the present utility model 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 the utility model stator includes but not limited to suspending motor, may extend to any motor.
