Description

A kind of energy-saving electromagnet

The utility model relates to a kind of basic electrical component, specifically a kind of energy-saving electromagnet.

We know that electromagnet is to utilize the iron-core coil of energising to attract armature or keep certain machine components, workpiece in a kind of electrical equipment of fixed position, can be widely used in various brakes, in electromagnetically operated valve and various electromagnetic relay and the contactor.In general, electromagnet is made up of coil, iron core and armature three parts.With regard to core configuration, at present, mainly contain two kinds of solenoid electromagnet and coiled electrical magnets, solenoid electromagnet produces attraction with the end face of iron core column in the coil, and coiled electrical magnet can produce attraction by the whole iron core face that comprises iron core cylinder and outside ring surface, like this when identical current excitation, air gap was less when solenoid electromagnet started adhesive, the suction-combining force is bigger, and after the adhesive, it is less to keep the suction-combining force; Air gap was bigger when coiled electrical magnet started adhesive, and the suction-combining force is less, and after the adhesive, its adhesive area is big, and it is bigger to keep the suction-combining force, and from energy-conservation angle, the two respectively has superiority, but all undesirable.At present, energy-saving electromagnet is arranged also, as patent 92216400.2, it is improved from coil and control circuit, reaching purpose of energy saving, and its complex structure, replacement is convenient inadequately.

The purpose of this utility model in order to overcome above-mentioned existing various electromagnetism iron deficioncies, provides a kind of simple and reasonable exactly, and control mode is consistent with traditional electromagnet, and it is easy to use to replace, and service behaviour is superior, and the energy-saving electromagnet that can cut down the consumption of energy significantly.

For achieving the above object, a kind of energy-saving electromagnet, it is provided with static iron core, coil, armature, it is characterized in that on the static iron core being provided with the magnetic conduction convex edge with the periphery of armature adhesive face.

The utility model is owing to be provided with the magnetic conduction convex edge on the static iron core, armature is included in the static iron core, when starting adhesive, because air gap is less, it is less to produce the needed starting current of enough the suction-combining forces, and after the adhesive, the adhesive area of static iron core and armature is bigger again, and keeping the required electric current of keeping of adhesive can be lower, thereby can reduce power consumption, reach purpose of energy saving, and other parts such as coil can be the same with traditional electromagnet, it is easy to use to replace.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structural representation.

As can be seen from Figure 1, a kind of energy-saving electromagnet, it is made up of static iron core 1, coil 2, armature 3, coil 2 is on the iron core column 4 of static iron core 1, can connect relevant control circuit, be used to the starting current that provides suitable and keep electric current, the setting of coil, the structure of control circuit, effect belong to prior art, and this does not describe in detail.On the utility model static iron core, the periphery of the adhesive face of itself and armature is provided with magnetic conduction convex edge 5, magnetic conduction convex edge and iron core integrative-structure, its whole armature adhesive bread with which, like this, when starting adhesive, can reduce the air gap of static iron core and armature, reduce and start exciting current, after the adhesive, because the adhesive area of static iron core and armature is big, being used to keep attract current also can be less.That is to say that the utility model all can have bigger gravitation under identical magnetomotive force when adhesive and after the adhesive, start gravitation or keep gravitation so can produce with less exciting current as the case may be.Thereby can reach purpose of energy saving.Push rod or pull bar and back-moving spring can be connected with on the utility model armature, brake, electromagnetically operated valve etc. can be made.

The utility model is simple and reasonable for structure, and service behaviour is superior, and saves energy significantly is applicable to the break-make of traction, braking and the control pipeline valve of various mechanical devices.
