The stator magnet yokes and teeth of the linear electric motor stator are made of the amorphous alloy material; the stator magnet yokes (21) and the teeth (24) are bonded by a binder (25) to form a magnetic core of a winding (22); the internal surfaces of the stator magnet yokes (21) and the teeth (24) are coated with epoxy resin cladding layers (23); the magnetic core of the winding for cladding the epoxy resin cladding layers (23) is placed in a metal substrate and fixed by a fastening piece (45) in a tooth socket; and the stator magnet yokes (21) and the teeth (24) are formed by winding amorphous alloy material thin strips or laminating the thin strips which are cut into pieces.
Description
Technical field
The present invention relates to the linear electric motors field, be specifically related to the linear motor rotor that a kind of primary side uses amorphous alloy material to make.
Background technology
Amorphous alloy material has very high magnetic permeability and low-down conductivity, in fields such as renewable energy power generation, power transmission and transformation, track traffics boundless application prospect is arranged.Use the electric equipment of its loss of electric equipment low-silicon steel sheet material far away of amorphous alloy material manufacturing, as the transformer that amorphous alloy material is made, its no-load loss such as reactor can reduce 70-80%.But owing to its Vickers hardness height, be about 5 times of ordinary silicon steel disc, bigger to its difficulty of cutting, shearing processing, also be difficult for punch forming simultaneously, usually can only lateral shear.Because electric rotating machine is circular, and the non-crystaline amorphous metal material is the strip of several fixed widths, need to constitute the rotary electric machine shape through a large amount of shearing assembly units, cause the processing technology complexity, cost is very high, the electric rotating machine of the special construction that amorphous alloy material makes is proposed to use based on these a lot of people, as patent CN1874113A, CN201222666Y, US6960860B1, US5903082 etc., the motor stator of wherein mentioning are different from silicon steel chip stator, silicon steel chip stator uses silicon steel sheet to be overrided to form vertically, and the stator of non-crystaline amorphous metal electric rotating machine uses amorphous alloy strips radially to reel from level to level to make, though reduced difficulty of processing like this, owing to magnetic flux is inhomogeneous, it is inhomogeneous to have produced heating again, problems such as electric efficiency reduction do not embody the characteristics of non-crystaline amorphous metal electrical machine energy-saving.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of linear motor rotor that adopts amorphous alloy material to use is proposed, the present invention can effectively reduce the processing to amorphous alloy material, can effectively reduce motor eddy current loss simultaneously, improves the motor operational efficiency; In addition, use the motor of amorphous alloy material in light weight in addition, volume is little, advantages such as frequency of utilization wide ranges.
Linear motor stator electric of the present invention comprises yoke, tooth, winding, folder etc.Wherein yoke and tooth use the amorphous alloy material manufacturing.The manufacture of stator yoke both can after also strip can being cut into pieces, be overrided to form by the amorphous alloy material thin coiled stock around forming.Stator tooth uses the same similar mode to process.The stator yoke and the tooth of amorphous alloy material bond with binding agent, constitute the magnetic core of winding.The inner surface of stator yoke and tooth scribbles the epoxy resin coating layer.The magnetic core that is coating the winding of epoxy resin layer is placed in the metal base, and fixes with the folder that is placed in the teeth groove, can guarantee that like this in motor operation course, stator tooth is stressed, distortion is less.Finally, stator, pedestal, the mover guide rail is connected as a single entity, and and mover between have air gap so that mover can be along guide rail movement.

Embodiment
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is several stator yokes of being made by amorphous alloy material and the pattern of tooth; As shown in Figure 1,11 is laminated type, is directly laminated by the isoplith amorphous alloy strips and makes, and laminating thickness can be by designing requirement; Shear the method that can directly use coiling in order further to reduce, winding form can be according to concrete position different designs.12 are the circle rectangular; 13 is elliptic; 14 is circular formula.
Figure 2 shows that the end view of the stator core that stator yoke and tooth etc. constitute; Stator yoke 21, stator tooth 24 are respectively the form shown in Fig. 1, and stator yoke 21 and tooth 24 use binding agent 25 to bond together, and constitute the magnetic core of winding 22.The inner surface of stator yoke and tooth scribbles epoxy resin coating layer 23, and winding 22 is laid in the teeth groove, and the winding magnetic core that is coating epoxy resin layer is placed in the metal base, and fixes with the folder that is placed in the teeth groove.
Fig. 3 a, b are depicted as the vertical view of stator yoke and tooth, and wherein stator tooth is the circle rectangular among Fig. 3 a, and stator tooth is circular formula among Fig. 3 b.31,32 are respectively amorphous alloy material stator yoke and tooth among the figure, and 33 is the epoxy resin coating layer, and 34 is stator winding.
Figure 4 shows that stator uses the platypelloid type structure of the linear motion actuator sketch of amorphous alloy material, pedestal 41, winding 42, stator yoke 43, folder 45, stator tooth 46, epoxy resin coating layer 48 common formation stationary parts among the figure, there are air gap 44 in mover table top 40, the sliver 49 common mover parts of forming between stator and the mover.Wherein winding 42, stator yoke 43, stator tooth 46, epoxy resin coating layer 48 are arranged by mode shown in Figure 2, constitute stator core, and stator core is placed in the pedestal 41, and folder 45 is placed in the stator teeth groove, and use bolt promptly to constitute stationary part.This structure can time distortion be less so that non-crystaline amorphous metal stator yoke 43 and tooth 46 are subjected to electric power, evades the frangible problem of amorphous alloy material preferably.Mover table top 40 is supported by directed guide rail 47, is in stationary part top; Sliver 49 is made of block of metal plate or clad metal sheet usually, installs over against stator, and the slit of itself and stator is air gap 44; After stator winding 42 energising, produce travelling-magnetic-field, sliver 49 is under the cutting of travelling-magnetic-field, and with induced electromotive force and produce electric current, the electric current of generation and air gap magnetic field interaction just produce electromagnetic push, and mover promptly moves along guide rail 47.Because very high magnetic permeability and the low-down conductivity of amorphous alloy material adopts this structure can effectively reduce motor eddy current loss, improve the motor operational efficiency.
Fig. 5 is the three-view diagram of folder 45 among Fig. 4.
