Abstract
The invention discloses a device which uses the non-magnetism moving conductors to drive the magnet to circumgyrate. The device includes the fixing base, non-magnetism moving conductor fixed on the fixing base, magnet near the non-magnetism moving conductor, drive shaft on the magnet and bracket of the fixing base where the drive shaft is fixed. In the device which uses the interaction between the induced magnetic field of the moving conductor and the magnetic field of the magnet to drive the magnet to circumgyrate, the magnet does not connect with the moving conductor and it can be used to develop new drive sets, sensors and equipments demonstrating the principle of the interaction between the permanent magnet and non-magnetism moving conductor. It also can be applied to the non-contacting driving in the exosomatic driving of the nanometer robot in the blood vessel, the exosomatic charge of the permanent endosomatic cardiac pacemaker and the non-contacting wheeled driving generator of the bicycles and other motor vehicles.
Description
Technical field
The present invention relates to a kind of device and method that utilizes non magnetic motion conduct magnet rotation.
Background technology
Electromagnetic induction phenomenon is one of discovery the most great in the electromagnetism, and it has disclosed the electric substantive characteristics that connects each other and transform with magnetic.Its discovery has promoted the develop rapidly of electromagnetic technique and the marked improvement of society.Based on the law of electromagnetic induction, people have invented by electrically driven (operated) motor with by mechanically operated generator, become the important motivity source of modern every profession and trade.But another kind of important forms of motion is arranged---the non-magnetic conductor of motion drives permanent magnet or electromagnet around the rotatablely moving of self symmetry axis in the noncontact mode since human in the past for electromagnetic induction interact understanding limitation and developed and utilized.The invention of this class Driving technique will be widely used in all kinds of high-tech areas.
Summary of the invention
The object of the present invention is to provide a kind of device that utilizes non magnetic motion conduct magnet to rotatablely move.
Another object of the present invention provide a kind of method of utilizing non magnetic motion conduct magnet to rotatablely move.
For achieving the above object, technical scheme of the present invention is:
Comprise a holder, holder is provided with a non magnetic motion conduct and a drive unit thereof, is provided with magnet near the non magnetic motion conduct, on the axisymmetric position of magnet rotating shaft is housed, and rotating shaft is fixed on the holder.
The present invention utilizes the method for non magnetic rotated conductors magnet rotation, and may further comprise the steps: magnet is set near non magnetic motion conduct, and magnet is provided with symmetrical rotating shaft.
Operation principle of the present invention is: when non magnetic motion conduct during with respect to magnet movement, because interacting, motion conduct and magnets magnetic fields cause that induced current produces induced field, this induced field and permanent magnet magnetic field interactions, make magnet when being subjected to the pull power consistent with the non-magnetic conductor direction of motion, also be subjected to of the effect of a shaft parallel in motion conduct and the rotating torque vertical with the conductor direction of motion, under the effect of this moment, magnet produces and rotatablely moves.
Beneficial effect of the present invention: 1) simple in structure; 2) do not have Mechanical Contact between two movable bodies, the adjusting of the mutual alignment that the occasion that needing can be widely used in noncontact to drive, the rotation direction of magnet and speed can be by the motion conduct direction of motion, movement velocity and motion conduct and magnets is controlled simply; 3) this with drive contactless whirligig and can be used for the drive unit of development of new and motion state senser element etc.For example: can be applicable to the external driving generating of the external driving of nanometer robot in the blood vessel, permanent intracorporeal heart pacemaker usefulness generator, the occasion that the contactless wheel drive generator of bicycle etc. needs noncontact to drive; 4) it is simple to operate, experimental result is vivid as the demonstration instrument of the interaction principle of permanent magnet and motion metallic conductor in the present invention, helps to deepen the understanding to electromagnetic induction phenomenon, the inspiration thinking.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
Fig. 2 is the structural representation of the embodiment of the invention 2.
Embodiment
Referring to Fig. 1, there is shown a kind of structure of device of non magnetic rotated conductors magnet rotation.Comprise holder 1, aluminium dish 5, disc permanent magnet 6 etc., motor 4 is fixed on the pole 2 of holder 1, and aluminium dish 5 is installed on the output shaft 4 of motor 3, on the disc permanent magnet 6 on aluminium dish 5 tops rotating shaft 7 is housed, rotating shaft 7 is positioned at the radial direction of aluminium dish 5, and is fixed on the support 8 of holder 1.
Replacements such as also available other nonmagnetic metal of the aluminium dish 5 among Fig. 1 such as copper, and can do globulate, cylindrical etc.Disc permanent magnet 6 also can be done globulate, other shape such as cylindrical.The also available electromagnet of disc permanent magnet 3 replaces elsewhere.
The operation principle of this whirligig is as follows: when aluminium dish 5 high speed rotating, the permanent magnet 6 that is arranged in aluminium dish 5 tops will produce induced current at aluminium dish 5, the magnetic field intensity of the size of induced electromotive force and permanent magnet 6, the angular velocity of rotation and this radius of aluminium dish 5 are relevant, induced field that this induced current produces and permanent magnet 6 interactions.When the rotating shaft 7 of permanent magnet 6 be in aluminium dish 5 radially the time, with the rotating shaft is the line of demarcation, the direction that permanent magnet 6 rotates in face of aluminium dish 5 can be subjected to the attraction of induced magnetism, then be subjected to the effect of repulsive force in the other direction, permanent magnet 6 this to the moment loading of power under around the shaft 7 the rotation, its rotary speed is directly proportional with the rotating speed of aluminium dish 5, and relevant with its residing position in aluminium dish 5.
Fig. 2 is the structure of the device of another kind of non magnetic rotated conductors magnet rotation.The main distinction of its Fig. 1 is that permanent magnet 5 is spheroid, and is positioned at the outside of aluminium dish 5 peripheries.When rotating under the drive of aluminium dish 5 at motor, spherical permanent magnet 57 is rotated under the effect of induced magnetism moment around the shaft.
In this device, motion conduct is that moment that magnet radially is subjected to and level pull power and also be directly proportional with the tangential linear velocity of conductor uniformly with respect to the speed of magnet.
In this device that utilizes the rotation of motion conduct induced field and magnets magnetic fields interaction magnet, magnet and motion conduct are contactless, can be used to drive unit, the transducer of development of new and the demonstration instrument that is used as permanent magnet and non magnetic motion conduct interaction principle.Also can be widely used in external driving, the external charging of permanent intracorporeal heart pacemaker of nanometer robot in the blood vessel, the occasion that bicycle or the wheeled driving generator of other motor vehicle non-contact type etc. needs noncontact to drive.
