Detailed description of the invention
Embodiment 1, Fig. 1 to Fig. 8 give a kind of linear electric machine and using method thereof realizing three class control based on ferrum gallium alloy;
Wherein, realize the linear electric machine of three class control based on ferrum gallium alloy and include stator core 6, linear axis 1 and brake;Stator
Linear axis 1 is set in iron core 6;Linear axis 1 includes ferrum gallium alloy 11, and is separately positioned on ferrum gallium alloy 11 arranged on left and right sides
Conducting magnet core 9;The conducting magnet core 9 of arranged on left and right sides is respectively provided with annular permanent magnets I 8 and annular permanent magnets II 12(ring
The magnetic pole of shape permanent magnet I 8 and annular permanent magnets II 12 is contrary, i.e. the lateral surface of annular permanent magnets I 8 is N pole, and ring-type forever
The lateral surface of magnet II 12 is S pole);Annular permanent magnets I 8 and annular permanent magnets II 12 are all ring-type by four 1/4th
Permanent magnet is spliced to form.Relative to ferrum gallium alloy 11, annular permanent magnets I 8 and annular permanent magnets II 12, at stator core 6
Inside it is respectively arranged with fine motion coil 5, Long travel coil II 7 and Long travel coil I 4;Respectively by Long travel coil II 7 and ring
Interaction between shape permanent magnet I 8 and Long travel coil I 4 and annular permanent magnets II 12, is formed to the right or to the left
Directed force F, then linear axis 1 just can be promoted to do Long travel motion to the left or to the right by this directed force F;And by micro-
Moving winding 5, then can drive ferrum gallium alloy to deform upon, the deformation occurred by ferrum gallium alloy, it is possible to achieve linear axis 1
Fine motion.
Brake is divided into left hand brake device 10 and right hand brake 2;Relative to the conducting magnet core 9 at linear axis 1 two ends, set respectively
Put left hand brake device 10 and right hand brake 2;It is respectively installed with spring on the conducting magnet core 9 at linear axis 1 two ends;Left end magnetic conduction
On iron core 9, one end of spring props up left hand brake device 10, and other end props up stator core 6;Spring on right-hand member conducting magnet core 9
One end prop up right hand brake 2, other end props up stator core 6;By spring, so that linear axis 1 is quick
Reset.
Brake includes flexible hinge and electric magnet, and flexible hinge is fixed on exterior support frame, and electric magnet is sucked type
Electric magnet, needs are braked when, electric magnet is passed through electric current, it is possible to by solenoid actuated flexible hinge directly
Frictional force, then braking linear axis 1 is formed on bobbin 1.Above-described stator core 6 is by permeability magnetic material or magnetic powder SMC
Material is constituted, and fine motion coil 5, Long travel coil II 7 and Long travel coil I 4 are all embedded in stator ferrum by coil brace
In core 6, coil brace is processed by nonmetallic materials nylon or bakelite.
The when of use, step is following, and (electric current being passed through in Long travel coil II 7 is Ia, is passed through in Long travel coil I 4
Electric current is Ib):
1, it is passed through forward current in Long travel coil II 7;It is passed through reverse current in Long travel coil I 4;Now, Long travel
After coil II 7 and Long travel coil I 4 interact with annular permanent magnets I 8 and annular permanent magnets II 12 respectively, produce from a left side
To right power directed force F, linear axis 1 is driven from left to right to move;
2, the when that linear axis 1 from left to right moving to the node specified, left hand brake device 10 is braked, straight limit axle 1
Motion from left to right;
3, Long travel coil II 7 and Long travel coil I 4 power-off respectively;
4, fine motion coil 5 is energized (fine motion coil 5 flow direction and annular permanent magnets I 8 and the magnetic flux of annular permanent magnets II 12
Direction is identical), ferrum gallium alloy 11 extends (ferrum gallium alloy 11 deforms upon in magnetic field) to the right, now, in step 2,
Left hand brake device 10 only limits the motion of conducting magnet core 9 on the left of ferrum gallium alloy 11, but ferrum gallium alloy 11 can after deforming upon
To extend to the right, the conducting magnet core 9 on the right side of ferrum gallium alloy 11 is not braked by right hand brake 2;
5, to the right fine motion to regulation stroke Δ L after, just braked by right hand brake 2, the conducting magnet core on the right side of restriction
The motion of 9, and cancel the braking of left hand brake device 10, fine motion coil 5 power-off, now, owing to ferrum gallium alloy 11 shortens Δ L,
But owing to the conducting magnet core 9 on right side is braked by right hand brake 2, it is impossible to retract, so, the conducting magnet core 9 in left side to
Race running Δ L;
6, by circulating above step 4 and step 5, it is possible to linear axis 1 to be carried out micron-sized driving, and by essence
Really control the electric current of fine motion coil 5, it is possible to linear axis 1 is carried out nano level driving.
If needing the Linear Control carried out from right to left, then have only on the basis of above step, input reverse electricity
Flow.
Contrasting above-described Long travel high position precision method by the present invention, intellectual material ferrum gallium is closed by patent of the present invention
Gold is applied in conventional linear motor so that Long travel detent mechanism and nano-positioning stage are the most separate, really realizes one
Body, substantially reduces whole device volume.Because Long travel uses linear electric motors and drives, present invention preserves method one
Advantage with three fast response times;Again because micrometric displacement uses intellectual material ferrum gallium alloy, its Micro-displacement Driving mode has again
The advantage of method two and four.To sum up, the carried structural saliency features of patent of the present invention is by linear electric motors driving, magnetostriction material
Material ferrum gallium alloy material stepper drive and micro-Locating driver combine together, have the excellent of volume stroke little, big and fast response time
Point.
Finally, in addition it is also necessary to be only the specific embodiment of the present invention it is noted that listed above.Obviously, the present invention is not
It is limited to above example, it is also possible to have many deformation.Those of ordinary skill in the art can be direct from present disclosure
The all deformation derived or associate, are all considered as protection scope of the present invention.
