Abstract

The utility model discloses a kind of non-fully contact sucked type electromagnet, there are a differences in height with outer ring for the iron core inner ring in sucked type electromagnetic actuation face, a fixed air gap is formed when actuation between sucker and electromagnetic actuation face, make sucker be attracted face non-fully to contact with electromagnetic actuation face, changes the remaining suction of electromagnet after the difference in height adjustment power-off of iron core Internal and external cycle.The utility model has the advantages that substantially reducing remaining suction when power-off between electromagnet and sucker, remaining suction can be adjusted flexibly.

Description

Non-fully contact sucked type electromagnet

Technical field

The utility model relates to the technical fields of sucked type electromagnet, in particular to a kind of non-fully to contact sucked type electromagnetism Iron.

Background technique

After the power-off of sucked type electromagnet, since magnetic material itself is there are due to remanent magnetism, between sucker and electromagnet still So there is certain suction, referred to as remaining suction.Existing sucked type electromagnet sucker is attracted face and electromagnetic actuation face is complete Contact, the i.e. outer ring 501 of iron core and inner ring 502 are contour, no differences in height, as shown in figure 3, existing sucked type electromagnet 5 is deposited Remaining suction is larger after a loss of power, and sucker can not be disengaged freely with electromagnet.This is that the application needs place improved emphatically.

Utility model content

Technical problem to be solved in the utility model is to provide for a kind of non-fully contact sucker for reducing remaining suction Formula electromagnet.

For the technical problem more than solving, the utility model, which provides, a kind of non-fully contacts sucked type electromagnet, institute The iron core inner ring for stating sucked type electromagnetic actuation face and outer ring are there are a difference in height, when actuation between sucker and electromagnetic actuation face A fixed air gap is formed, so that sucker is attracted face and is non-fully contacted with electromagnetic actuation face, change the difference in height tune of iron core Internal and external cycle The remaining suction of electromagnet after whole power-off.

The iron core inner ring height is lower than outer ring height.

For the utility model when sucker and electromagnetic actuation, it is non-fully to contact that sucker, which is attracted face with electromagnetic actuation face, There are an air gaps in its circuit.Since iron core circuit is in magnetic saturation or close to magnetic saturation state, gas when electromagnet is powered Influence of the gap to entire iron core circuit is smaller, and the suction-combining force loss is little；Iron core circuit is unsaturated when power-off, and air gap increases back Road magnetic resistance reduces remaining suction.It is attracted the difference in height in face by adjusting outer iron core in electromagnet, adjusts remaining suction.

Superior effect of the utility model is:

1) remaining suction when substantially reducing power-off between electromagnet and sucker；

2) structure is simple, flexible design, and remaining suction can be adjusted flexibly.

Specific embodiment

The embodiments of the present invention are described in detail below in conjunction with attached drawing.

Fig. 1 shows the structural schematic diagram of the utility model embodiment, and Fig. 2 shows the structures of the utility model embodiment Exploded view.As shown in Figs. 1-2, the utility model provides a kind of non-fully contact sucked type electromagnet, and the actuation face of sucker 1 is One plane, 302 height of iron core inner ring in sucked type electromagnetic actuation face are lower than 301 height of outer ring, sucker and electricity when actuation A fixed air gap 4 is formed between magnet actuation face, so that sucker is attracted face and is non-fully contacted with electromagnetic actuation face, changes in iron core The remaining suction of electromagnet after the difference in height adjustment power-off of outer ring.

For the utility model when sucker 1 and electromagnetic actuation, it is non-fully to contact that sucker, which is attracted face with electromagnetic actuation face, There are a fixed air gaps 4 in its circuit.Since iron core circuit is in magnetic saturation or close to magnetic saturation shape when electromagnet is powered State, influence of the fixed air gap 4 to entire iron core circuit is smaller, and the suction-combining force loss is little；Iron core circuit is unsaturated when power-off, Gu Determine air gap 4 and increase circuit magnetic resistance, reduces remaining suction.It is attracted the difference in height in face by adjusting outer iron core in electromagnet, adjusts Whole residue suction.

The utility model sucked type electromagnet residue suction greatly reduces, and as needed, is meeting energization suction Under the conditions of be adjusted flexibly, this is that existing sucked type electromagnet institute is unappeasable.

The foregoing is merely the preferred embodiments of the utility model, are not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included in the protection scope of the utility model.

Claims
