First and second connecting rods 3, about 4 pass through the middle part of permanent magnet skeleton, for example, by nut or other special companies
Connection mechanism is fixed on permanent magnet skeleton in connecting rod.Also, the first and second connecting rods can be together by a threaded connection.
In this manner it is possible to by the annular permanent magnet up and down 2 for linking together, the connecting rod 3,4 of permanent magnet skeleton 5 first and second, as
Vibrator component is integrally suspended at the inside of the bracing frame 1 in outer sleeve 7.
It should be strongly noted that the produced magnetic direction after magnetizing of symmetrical permanent magnet is powered with coil 6
The magnetic direction for producing afterwards is formed with certain angle.The maximum in order that electromagnetic actuator of the present utility model is exerted oneself, preferably
It is that, in the case where the mode as depicted of coil 6 winds, annular permanent magnet is radial magnetizing.
Multiple spring leafs 8 are respectively placed in the top and bottom of bracing frame 1, and pass through the first and second connecting rods 3 at middle part,
4 are fixedly connected into an entirety with vibrator component, for example, be fixed together by nut.First and second connecting rods can be upper
Lower structure, is threaded connection, and is vertically connected with bar 3,4 by the two and spring leaf 8 is connected into integral with oscillator.Connect up and down
Extension bar 3,4 not only can stationary annular permanent magnet 2, support spring piece 8, moreover it is possible to play a part of magnetic conduction.
When movement of pendulum, spring leaf 8 is transferred force to by being vertically connected with bar 3,4, acted in the restoring force of spring leaf 8
Under return to original position.After coil 6 is powered, oscillator moves reciprocatingly under the effect of suffered electromagnetic excitation power, so as to produce work
The control to controlled device is firmly effectively realized, to reduce the response of controlled device.
As shown in figure 1, spring leaf 8 is fixedly connected by bolt hole with support block 1, while also being connected using press-fit approach.
Outer sleeve 7, bracing frame 1, annular permanent magnet 2 and permanent magnetism iron skeleton 5 constitute the field circuit of closing.The quantity of spring leaf can
To change the rigid demand with system, such as big for rigid requirements electromagnetic actuator can be by the quantity of upper and lower spring leaf
Respectively it is set to two or more.
Additionally, the displacement in order to reduce spring leaf during vibration, the step in the annular for be attached to spring pressure bracing frame
After upper, further spring leaf can also be fixed by the screw nut of spring leaf surrounding.
Due to the sleeve that outer sleeve of the present utility model is made for non-magnet material, coil is wrapped on bracing frame, coil
It is connected with control power supply.When aliving in coil 6, oscillator will in the presence of electromagnetic force forced vibration, spring leaf shaking
Move reciprocatingly in the presence of sub suffered electromagnetic force, there is provided lasting restoring force, realize the control to controlled device.
Specifically, after coil 6 is powered, for example, it is connected with external system by interface 10 as shown in Figure 2 and receives electricity
Stream signal, the magnetic field interaction that annular permanent magnet 2 is produced with coil 6 produces electromagnetic force, drives annular permanent magnet, permanent magnet
Skeleton 5 and be vertically connected with bar 3,4 motion.Because connecting rod 3,4 is connected with spring leaf 8, therefore, when spring leaf outer ring is consolidated
It is fixed, you can to provide continuous elastic restoring force in lasting motor process, make oscillator do continuous reciprocating motion, so as to reality
Now to the active control vibrated, reduce the response of controlled device.
In order to reduce the friction produced with bracing frame during oscillator vibration, it is provided between bracing frame 1 and permanent magnet 2 certain
Air gap.Preferably, the width of the air gap is less than 2mm.
As shown in figure 3, being additionally provided with multiple louvres on permanent magnet skeleton.These louvres are shaped as sector, so
Design be more beneficial for electromagnetic actuator work when radiating.
