Abstract
The utility model discloses a permanent magnet synchronous linear motor (PMSLM) comprising a rotor and a stator, wherein, the rotor comprises an iron core formed by superposing an effective quantity of silicon steel sheets upon one another, and a magnetizing coil embedded on the iron core; the surface of each silicon steel sheet is covered with an insulating cold layer which is a water-soluble epoxy resin layer with self-adhesion performance. The technical scheme provided by the utility model is as follows: the silicon steel sheet of the iron core in the motor is covered with the water-soluble epoxy resin cold layer; and due to the physical characteristics of high polymers comprising the water-soluble epoxy resin cold layer, the silicon steel sheets with cold layers are bonded as an integrated iron core in an environment at a certain pressure and temperature after a certain period of time. The integrated iron core has the advantages of good interface resistance and adhesion firmness, and excellent thermal conductivity, is free of AC electromagnetic noise, and never breathes as temperature changes, thereby avoiding interface corrosion.
Description
Technical field
The utility model relates to a kind of linear permanent magnet synchronous motor.
Background technology
Be used for high accuracy, at a high speed, the linear permanent magnet synchronous motor of high rigidity servo system, flat, in light weight in order to make motor size, iron core all adopts by certain folded thick electromagnetic silicon steel sheets to be formed, and the punching thickness of silicon steel sheet generally only is tens millimeters.In the punching of tens millimeters thick, also want the groove of punching out some, to embed the electromagnetism winding.In the prior art, it is earlier silicon steel sheet to be carried out initial laminating that silicon steel plate stacking becomes the method for whole iron core, adopts riveted joint or welding to carry out the last fastening whole iron core that forms then.This method can not reach fitting like a glove between silicon steel sheet and the sheet owing to the dispersed and distributed of fastening point position, and the interface resistance between silicon steel sheet and the sheet is increased, thereby makes motor steady and high noisy occur when operation.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of linear permanent magnet synchronous motor to be provided, and it has extraordinary low noise, operates steadily, and response is fast, characteristics such as reliable in quality.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of linear permanent magnet synchronous motor, comprise mover and stator, described mover comprises that iron core that the silicon steel plate stacking by effective quantity forms and the magnet exciting coil that is inlaid on the iron core constitute, all apply one deck insulating cold layer on the surface of described every silicon steel sheet, this insulating cold layer is the water miscible epoxy resin layer that has from bonding performance.
Above-mentioned linear permanent magnet synchronous motor, wherein, the described every silicon steel sheet that is positioned at the iron core middle part is the double-coated epoxy resin layer, the silicon steel sheet that is positioned at the iron core upper and lower end face applies epoxy resin layer on the single face relative with the adjacent silicon steel disc.
Above-mentioned linear permanent magnet synchronous motor, wherein, the thickness of double-coated epoxy resin layer is 3～5um on the described silicon steel sheet, the thickness of single face coating epoxy resin layer is 5～7um.
Adopted the technical scheme of linear permanent magnet synchronous motor of the present utility model, promptly on the silicon steel sheet of electric machine iron core, apply the cold layer of the water miscible epoxy resin of one deck, utilize the physical characteristic of the cold floor height polymers of water miscible epoxy resin matter, just be bonded as a whole iron core through the silicon steel sheet that looses with cold layer under certain pressure, the temperature and time, concrete good interface resistance and the bonding fastness of this whole iron core, and has a good heat conductivity, the noise of no alternating electromagnetic, and can " not breathe " with variation of temperature, so just avoid layer corrosion.The linear permanent magnet synchronous motor that this iron core constitutes has extraordinary low noise, operates steadily, and response is fast, characteristics such as reliable in quality.
Description of drawings
Fig. 1 is the structural representation of linear permanent magnet synchronous motor of the present utility model;
Fig. 2 is the front view that constitutes the silicon steel sheet of iron core in the linear permanent magnet synchronous motor of the present utility model;
Fig. 3 is the cutaway view that constitutes the silicon steel sheet of iron core in the linear permanent magnet synchronous motor of the present utility model.
Embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 to Fig. 3, linear permanent magnet synchronous motor of the present utility model, comprise mover 1 and stator 2, wherein, mover 1 comprises iron core 11 and the magnet exciting coil 12 that is inlaid on the iron core 11 constitutes, and this iron core 11 is overrided to form by the effective silicon steel sheet 3 of quantity, all applies one deck insulating cold layer 111 on the surface of every silicon steel sheet 110, this insulating cold layer 111 is for having the water miscible epoxy resin layer from bonding performance, wherein
The every silicon steel sheet 110 that is positioned at the iron core middle part is the double-coated epoxy resin layer, and the thickness of this coated on both sides is 3～5um; The silicon steel sheet 110 that is positioned at the iron core upper and lower end face applies epoxy resin layer on the single face relative with adjacent silicon steel disc 110, the thickness of this single face coating is 5～7um.
After linear permanent magnet synchronous motor of the present utility model adopts and is coated with the silicon steel sheet 110 of water miscible epoxy resin layer, become required punching shape through the punching press punching out, in special use laminates mould, with to fold thick be discharged to satisfy after, keep constant pressure, send into baker, in uniform temperature and in the time, take out workpiece, pull down mould, the diffusing silicon steel sheet 110 of the cold layer of tape insulation just is bonded as a whole iron core 11, these whole iron core 11 concrete good interface resistance and bonding fastness, and have good heat conductivity, no AC noise, and do not vary with temperature and can " breathe ", so just avoided layer corrosion.
Linear permanent magnet synchronous motor of the present utility model has extraordinary low noise, operates steadily, and response is fast, characteristics such as reliable in quality.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
