According to the technical scheme, the accuracy and controllability of the high frequency movement of the electromagnet are effectively achieved, so that the application scope of the electromagnet is expanded; the electromagnet can remain a raw state for a certain time after losing power, so that the energy consumption can be reduced, and the service life of the electromagnet is prolonged.

Description

The unidirectional Self-retaining electromagnet of pulsed

Technical field

The utility model relates to a kind of electromagnet, is the unidirectional Self-retaining electromagnet of pulsed specifically.

Background technology

Electromagnet is an ancient electric component, produces this principle of magnetic field and used for a long time after helical coil energising.The principle of present technique fusion electromagnetic field and permanent magnetic field is designed and developed.The shortcoming of prior art: electromagnet produces magnetic field under "on" position, make iron core action, once power-off magnetic field just disappears, moving iron core is just out of hand, therefore after will keeping the moving iron core energising work of electromagnet, state just must be switched on constantly, will consume like this energy and make electromagnet heating, thereby affect the life-span.

Utility model content

For some equipment requirement electromagnet, use the method for pulse power supply to carry out work, to reduce the consumption of the energy, after dead electricity, still maintain the original state and there is certain confining force, require the moving iron core energy back and forth movement of electromagnet, the utility model provides pulsed unidirectional Self-retaining electromagnet, and object addresses the above problem.

The utility model is achieved through the following technical solutions: the unidirectional Self-retaining electromagnet of a kind of pulsed, comprise shell, cover plate, static iron core, skeleton, coil and permanent magnet on moving iron core and skeleton, described static iron core is assemblied in the bottom of shell, described cover plate is fixing in the enclosure by skeleton, described moving iron core is arranged in skeleton, and can be in skeleton free back and forth movement, described coil connects external connection, on described skeleton, be equipped with long group coil and short group of coil, described external connection connects long group coil and short group of coil, described skeleton is three-chamber skeleton, centre is provided with and is four groups of rectangular cavities that circumference distributes on four sides, assembling and positioning permanent magnet in described rectangular cavities, described permanent magnet is circumferential arrangement.

As preferably, described static iron core and shell adopt the mode of spinning riveting.

As preferably, described shell and cover plate link arrange some tooth pieces, and described tooth piece mutually mates and fixes with the opening arranging on cover plate.Stiffened shell is connected with cover plate, guarantees whole robustness

As preferably, described cover plate is two.

As preferably, described permanent magnet is four.

The utility model has been taked after abovementioned technology, its beneficial effect is remarkable: the technical solution of the utility model has solved accuracy and the controllability of electromagnet high frequency motion effectively, the utilization of therefore having expanded electromagnet, make it after dead electricity, still can maintain the original state and have certain confining force, its confining force can continue random time, so just can reduce energy consumption, also extend to some extent the useful life of product.

Accompanying drawing explanation

Fig. 1 is the general assembly explosive view of the utility model embodiment 1;

Fig. 2 is the structural representation of the utility model embodiment 1.

In figure, 1 is shell, the 2nd, and static iron core, the 3rd, skeleton, the 4th, long group coil, the 5th, short group of coil, the 6th, permanent magnet, the 7th, external connection, the 8th, cover plate, the 9th, moving iron core, the 10th, tooth piece.

Embodiment

Contrast accompanying drawing is below further described the utility model in conjunction with the embodiments.

Reference is as Fig. 1, shown in Fig. 2, the unidirectional Self-retaining electromagnet of pulsed, comprise shell 1, cover plate 8, static iron core 2, skeleton 3, moving iron core 9, permanent magnet, skeleton is three-chamber skeleton, static iron core 2 is assemblied in the bottom of shell 1, static iron core 2 and shell 1 adopt the mode of spinning riveting, moving iron core 9 is arranged in skeleton 3, and can be at the interior free back and forth movement of skeleton 3, assembling long group coil 4 and short group of coil 5 on skeleton 3, long group coil 4 is all connected external connection 7 with short group of coil 5, in the middle of skeleton 3, be provided with and be four groups of rectangular cavities that circumference distributes on four sides, in above-mentioned rectangular cavities, assemble permanent magnet 6, permanent magnet 6 is circumferential arrangement, this skeleton 3 is installed in shell 1 and with cover plate 8 and fixes afterwards, an integral body is fixed in two cover plates 8 stacks, shell 1 arranges some tooth pieces 10 with two cover plates 8 links, tooth piece 10 mutually mates and fixes with the opening arranging on cover plate 8.

Static iron core is fixed in shell, and forms a magnetic circuit by shell and permanent magnet, and its polarity is the S utmost point.When long group coil one pulse current is given by external connection in outside, long group coil produces an electromagnetic field and the moving iron core of magnetization is the N utmost point, according to the magnetic field principle that there is a natural attraction between the sexes, moving iron core moves to static iron core, after external power source disappears, utilize the moving iron core of magnetic attracting of permanent magnet to make iron core keep motionless.When short group of coil one pulse current given by external connection in outside, short group of coil produces an electromagnetic field and magnetize moving iron core is the S utmost point, and according to the principle of magnetic field two like magnetic poles repel each other, moving iron core leaves static iron core as anti-phase motion.According to need of work, constantly wheel is given long and short group of coil power supply, just can make constantly back and forth movement of iron core.

What more than enumerate is only specific embodiment of the utility model, and obviously, the utility model is not limited to above embodiment.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should belong to protection range of the present utility model.
