Fig. 2 is the magnetic conduction frame window structural representation among the embodiment;
Fig. 3 is the magnetic pole arrangement form schematic diagram of embodiment middle rare earth permanent magnet;
Embodiment
Below in conjunction with an accompanying drawing and a specific embodiment the utility model active vibration damping device is described in further detail.
Fig. 1 is a preferred embodiment of this utility model, and it is installed in one group of (four) rare-earth permanent magnet 102 on the magnetic conduction framework 101 by magnetic conduction framework 101, and can power up multiturn coil 103 compositions.Among this embodiment the structure of magnetic conduction framework is optimized, the two ends up and down of magnetic conduction framework 202 have a rectangular opening 201 as shown in Figure 2, can significantly improve the distribution situation of the magnetic line of force in the closed magnetic circuit that magnetic conduction framework and rare-earth permanent magnet form like this, it is more reasonable that thereby the magnetic line of force that makes coil 103 residing magnetic field spaces distributes, and makes whole powered coil structure efficiency higher.
Powered coil structure as shown in Figure 1, multiturn coil 103 is in the space with closed magnetic field of magnetic conduction framework 101 and rare-earth permanent magnet 102 formation, the magnetic pole arrangement form of rare-earth permanent magnet 102 in magnetic conduction framework 101 as shown in Figure 3, two long limits of multiturn coil 103 are in respectively in the opposite magnetic field of both direction, in multiturn coil 103, feed a certain size electric current, because current direction is opposite in two limits of multiturn coil 103, their residing magnetic directions are opposite simultaneously, therefore the both sides of coil will be subjected to the promotion of the electromagnetic force of equidirectional, thereby make coil in magnetic field and coil, obtain a certain size electromagnetic force on the electric current orthogonal direction, regulate the size that the big young pathbreaker who feeds electric current in the multiturn coil 103 directly changes the electromagnetic force of acquisition.Because the Surface field density of rare earth permanent-magnetic material is very high, while is less by the flat spatial separation that four unidimensional rare-earth permanent magnetic film amalgamations form, therefore very high and uniformity of magnetic field of the magnetic field intensity in multiturn coil space of living in and stability are all very high, thus the electromagnetic force that obtained of multiturn coil 103 energising backs not only strength strong and in the certain movement scope size stable.The powered coil structure of being made up of above-mentioned part not only has power output stable and that the linearity is good, and response speed is fast, and compact conformation is the very wide new structure of a kind of practicality.
The above is a DETAILED DESCRIPTION OF THE PREFERRED of the present utility model and accompanying drawing, is not that scope of the present utility model limits.For method and apparatus of the present utility model, all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
