Description
Technical field
The utility model is that one utilizes electromagnetic induction principle, and the inductive loop magnetic field interaction in externally-applied magnetic field and electric conducting material produces magneticaction device, belongs to electricity, permanent magnetic chuck industry.
Background technology
As everyone knows, the application of magnechuck or permanent magnetic chuck widely, such as: the electromagnetism of hoisting equipment or permanent magnetic chuck; The quick-clamping of metal cutting process lathe; Quick die change of injection molding machine etc., but the application of above all traditional electrical magnetic-discs or permanent magnetic chuck, all can only adsorb or a kind of magnetic conductive material of lifting.For non-magnetic electric conducting material such as: copper, aluminium, stainless steel and many non-magnetic steel alloys etc. all cannot produce magneticaction.As long as the utility model object is to provide one electric conducting material all can device magneto motive with its generation, fill up the blank of this type of technology.
Utility model content
Technical problem to be solved in the utility model is: to the thorough innovation of traditional electrical magnetic-disc or permanent magnetic chuck, and solving it can not the problem of the non-magnetic electric conducting material of lifting, and concrete scheme is as follows:
A kind of magneticaction device of electric conducting material, together with this device is pressed close to electric conducting material, inductive loop can be produced in electric conducting material, be made up of conducting magnet core and pitch of the laps winding, iron core can be disc, semi-cylindrical, hemisphere or other is randomly topologically structured, and iron core is slotted with damascene wiring winding, coil windings is the symmetrical any polyphase windings connected, external three-phase or polyphase source, its principle producing rotating magnetic field is the same with the principle that motor produces rotating magnetic field.
The magneticaction device of electric conducting material makes sucker form, and sucker also can be made up of permanent magnet N pole, the S pole p-m rotor formed of alternately arranging, and described p-m rotor is by driving mechanism driven rotary thus form the rotating magnetic field that permanent magnet produces.
Operation principle of the present utility model is: when the sucker of generation rotating magnetic field is near electric conducting material, inductive loop will be produced according on the known electric conducting material of Faraday's electromagnetic induction law, and then generation induced field, the rotating magnetic field interaction of induced field and sucker can produce two attributes: one is and the electromagnetic torque of rotating magnetic field with rotation direction; An electromagnetic force being perpendicular to inductive loop plane or curved surface.The direction of this electromagnetic force can be suction, can be also repulsive force, depend on the rotary speed of rotating magnetic field, and its size is magneticaction device of the present utility model to electric conducting material magnetic force size.
The rotary speed of the rotating magnetic field that magneticaction device produces has a critical whirling speed, if critical whirling speed is n1, the rotating speed of rotating magnetic field is n, the intensity of rotating magnetic field is B, inductive loop magnetic field intensity in the electric conducting material be close with rotating magnetic field is b, the impedance of electric conducting material is z, then when n is less than n1, magneticaction device and electric conducting material attracting; When n is greater than n1, magneticaction device and electric conducting material repel each other; Wherein, when B strengthens, corresponding b also becomes large, and z is constant, and n1 diminishes.
For eliminating the impact of electromagnetic torque, Acetabula device can match uses, and the direction of rotation of the rotating magnetic field of Acetabula device that pairing uses is contrary, and the direction of the electromagnetic torque of generation so also on the contrary thus cancel out each other.
Beneficial effect:
1. magneticaction device of the present utility model solves traditional electrical, permanent magnetic chuck can not the difficult problem of the non-magnetic metal material of lifting.
2. magneticaction device of the present utility model can be applied to and manufacture a kind of magnetic force suspension device be suspended in above electric conducting material newly.
