Description
Technical field
The present invention relates to electromagnet technical fields, more particularly to a kind of super-silent electromagnet.
Background technique
Existing electromagnet, because it is relative to servo motor fast response time, low in cost, installation is simple more and more
Substitution servo motor etc. be widely used in finance device, industrial equipment, automobile, agricultural equipment, security mask and household electric
The all trades and professions such as device, wherein be greatly the product that can all encounter in real time in people's life, but existing electromagnet relative to
The apparent defect of servo motor, noise is big, and the common electromagnet noise that noise reduction is not added can reach 75~90dB or more, to people
Life usually brings many noise pollution, for this status, a kind of super-silent electromagnet of market increasingly demand, and application
In the occasion of the various mute requirements of height.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of super-silent electromagnet, can be realized super-silent effect.
The technical solution adopted by the present invention to solve the technical problems is: a kind of super-silent electromagnet is provided, including iron frame,
Spool and movable core, the iron frame interpolation have spool；It is wound with conducting wire on the lower part of the spool and forms line package；The line
The outer ledge on the top of axis is provided with magnetic conduction sheet；Magnet is provided between the magnetic conduction sheet and iron frame；It is arranged on the iron frame
There is lower cover, the magnetic conduction sheet, magnet and line package are fixed between the iron frame and lower cover；The movable core is with button
Ring, and pass through spring and iron frame is entered by the spool inner hole group；One end of the spring is affixed on the bottom of iron frame, other end fitting
The retaining ring；The movable core is maintained at by the elastic force of the spring and the suction of the magnet when conducting wire no power
At the balance of magnet suction and spring force；The conducting wire generates identical as the suction direction of the magnet after the conducting wire energization
Magnetic field, the movable core, which is increased by suction to the position of the lower cover, to be moved, and is stayed between the lower cover after stop motion
There is gap.
The lower cover is arranged on iron frame by way of twisting.
The magnetic conduction sheet enters the outside that spool fits in the top of spool along the step circles group of the spool.
The conducting wire is copper wire.
Beneficial effect
Due to the adoption of the above technical solution, compared with prior art, the present invention having the following advantages that and actively imitating
Fruit: the present invention, which cancels in conventional electromagnets, reaches super-silent effect without any mechanical impact under secured core position realization energized state
Fruit, actual noise can be controlled in 45dB hereinafter, far below 75~90dB of general electromagnet.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
Embodiments of the present invention are related to a kind of super-silent electromagnet, as shown in Figure 1, include iron frame 1, lower cover 2, magnet 3,
Spool 4, movable core 5, magnetic conduction sheet 6, copper wire 7, spring 8 and retaining ring 9, the copper wire 7 are around on the lower part of the spool 4 and form
Line package, the spool group enter in the iron frame 1, and line package is made to be located at the lower part of iron frame 1, and the magnetic conduction sheet 6 is along described
The step circles group of spool 4 enters to be fitted in the outside on 4 top of spool, the magnet 3 be located at the magnetic conduction sheet 6 and the iron frame 1 it
Between, the lower cover 2 and the mutual twisting of the iron frame 1, by the magnetic conduction sheet 6, magnet 3 and line package be fixed on the iron frame 1 with
Between lower cover 2.The retaining ring 9 is provided on the movable core 5, movable core 5 passes through the spool after passing through the spring 8
4 inner hole group enters iron frame, and one end of spring 8 fits in the bottom of iron frame, and the other end fits in retaining ring 9.
Copper wire of the invention is under no power situation, elastic force and the magnet 3 of the movable core 5 by the spring 8
Suction, be maintained at the suction of magnet 3 and the Spring balanced of spring 8.After copper wire of the invention is powered, the copper wire 7 is generated
Magnetic field identical with the suction direction of the magnet 3, attraction suffered by the movable core 5 increase, the position of Xiang Suoshu lower cover 2
Movement, and eventually stop at a position, also there are gaps between the position stopped and the lower cover.
It is not difficult to find that the present invention breaches original electromagnet mechanical impact completely, the disadvantage of noise overall situation pollution is realized
Without mechanical impact, noise is lower than the super-silent electromagnet of 45dB, to the more comfortable environment that the Working Life of people provides, subtracts
The generation of noise pollution is lacked.
