12, left spring 11, right spring 13.The flange of left yoke 2 and right yoke 9 is matched with the skeleton 5,7 of two control coils, and skeleton is
Weak permeability magnetic material has an annular magnetizer 6 between two skeletons, matched in the axial direction, forms sealing function.Yoke 2,9,
Shell 3, annular magnetizer 6 are magnetizer, collectively form magnetic circuit with permanent magnet 12.Mechanical spring is arranged with outside push rod 1,10
11,13, permanent magnet 12 is movable member, can the free movement in annular magnetizer 6 and two skeletons 5,7 composition inner hole.
As shown in Fig. 2, two coils 4,8 of control are passed through the electric current of opposed polarity according to the polarity of permanent magnet 12, make permanent magnet
12 obtain the driving force of horizontal left-hand or dextrad, and in the present embodiment, left coil 4, right coil 8 are 1500 circles, 4 electric current of left coil
Inwards, right coil 8 is passed through that the vertical paper of electric current is outside, and left 2 right side magnetizer of yoke induces the pole S at this time to vertical paper, and forever
Attraction is generated between magnet 12, right 9 left side magnetizer of yoke induces the pole S, and repulsion is generated between permanent magnet 12, and two power are total
Same-action moves downward permanent magnet 12, therefore the power output of electromagnet is also significantly improved.If converting two control coils 4,8
It is passed through the polarity of electric current or changes the polarity of permanent magnet 12, permanent magnet 12 can be driven to move right.
As shown in figure 3, gravitation F1Increase with displacement and increases, repulsion F2Increase with displacement and reduces, reasonable Set scale electricity
