Abstract
The utility model provides a double magnetic passage of electromagnetism and permanent magnetism combined magnetic force device, which consists of an electromagnetism passage system, namely, a magnetism source, a permanent magnetism passage system, namely, a magnetic faceplate, and a magnetic separation layer. The electromagnetism passage system is a reverse-m shaped magnetism source structure; the permanent magnetism passage system is formed by setting a high coercive force Nd-Fe-B square magnetic steel of which the polarity is irreversible in a square frame shaped magnetic faceplate. A magnetic separation layer is arranged between the two magnetic passages, the coercive force of an Al-Ni-Co magnetic disk of which the polarity is reversible in the magnetic separation layer is lower, the polar directions of the north and the south poles of the Al-Ni-Co magnetic disk can be controlled by the electromagnetism passage. By the magnetic lines, of which directions are uniform with or opposite to the direction of the magnetic field of the permanent magnetism passage system, and which are generated by the electromagnetism passage system, the double magnetic passage of electromagnetism and permanent magnetism combined magnetic force device overlaps or eliminates the magnetic force. When the electromagnetism passage system suddenly breaks in electricity or goes wrong, the permanent magnetism passage system can individually perform the magnetic fastness protecting function. The double magnetic passage of electromagnetism and permanent magnetism combined magnetic force device has especially strong magnetic force, excellent rigidity, and good safety and reliability and saving energy and electricity.
Description
Affiliated technical field
The utility model relates to a kind of electromagnetism and adds permanent magnetism double magnetic circuit combined magnetic power apparatus.Be used for machine industry as location and fixing magnetic force instrument.
Background technology
Traditional permanent magnetic device all adopts the mode of machinery dislocation or rotary magnetic steel to reach the purpose that magnetizes, demagnetizes, and its shortcoming is:
1, the excessive or suspicion of inconvenient operation of magnetization, demagnetization operating physical force is arranged for large-scale permanent magnetic device.
2, be difficult to far distance controlled.
3, permanent magnetism disk card bearing capacity is poor usually, when disk is used for the bigger various press of pressure-bearing, the disk panel deformation might occur, has influence on the activity of magnet steel, and the operation of magnetization, demagnetization can't be carried out.
Summary of the invention
The utility model adopts the chevron electromagnetism magnetic source magnetic circuit system and the fixing permanent magnetism magnetic source magnetic circuit system composition electromagnetism of magnet steel group to add permanent magnetism double magnetic circuit combined magnetic power apparatus.Direction and size by the conversion exciting curent realize the stack of magnetic force or the purpose of counteracting.
The utility model is achieved by the following technical solution: electromagnetism adds permanent magnetism double magnetic circuit combined magnetic power apparatus and has electromagnetic circuit system and permanent magnetic circuit system.The electromagnetic circuit system is made up of magnetizing coil, iron core and yoke seat.The permanent magnetic circuit system can not inversion neodymium iron boron side magnet steel by polarity and the disk panel form, magnet steel is embedded in the dead slot of the main pole of disk panel and disk panel housing, can form the permanent magnetic field that a constant polarity can not inversion.Be provided with the magnetic separator between two systems.Polarity possibility of reversal aluminium nickel cobalt circle magnetic sheet in the magnetic separator is subjected to the control of electromagnetic field direction variation, can change the direction of the N utmost point, S utmost point magnetic pole, and it plays the effect that connects and control two magnetic circuit system magnetic lines of force trends.Produce by the electromagnetic circuit system with the identical or opposite magnetic line of force of permanent magnetic circuit system magnetic field direction, reach the stack of two system's magnetic lines of force or subdue.The forward that the electromagnetic circuit system the passes to moment electric current that magnetizes, the reversing that makes polarity possibility of reversal alnico magnet to polarity can not the identical direction of inversion Nd-Fe-B magnet steel polarity, pass to subsequently forward less keep electric current, the stack of existing electromagnetic force and permanent magnetism power at this moment, not having too high temperature rise again, is normal operating state.Electromagnetic circuit system passes to reverse demagnetization current of moment, the polarity upset of the alnico magnet of polarity possibility of reversal is arrived and the opposite direction of the irreversible Nd-Fe-B magnet steel magnetic pole of polarity, at this moment closed in the different magnet steel magnetic lines of force of two classes, make whole magnetic means not show that magnetic is demagnetized state.When the electromagnetic circuit system breaks down or cuts off the power supply, the permanent magnetic circuit system will play the magnetic force fixation separately.
The utility model has big, the good rigidly, safe and reliable of magnetic force compared with traditional magnetic means, remarkable advantage that can straighforward operation.
