Embodiment
The invention will be further described below in conjunction with drawings and Examples.
In Fig. 1, the present invention includes by fairlead, be contained in yoke 1,6 in fairlead two stomidiums, be contained in the basin shape pole shoe parts that two ends are made up of the armature 11 of output push rod 16 in fairlead and two yokes, 1,6 holes; Fairlead both sides in housing 4 are equipped with control coil 2,5 respectively; Fairlead is separated into three sections fairleads 9,12,15 with nonmetal magnetism-isolating loop 10,13 and seam is an integral body.On middle one section fairlead 12, annular permanent-magnet body 3 is housed.Two basin shape pole shoes have an angle α with separately fairlead 15,9 respectively.
Housing 4 is made by the good hollow housing of magnetic property.The middle part of housing 4 has an opening mounting receptacle to be connected with the control electronic circuit.The yoke 1,6 of soft magnetic material respectively is equipped with at the two ends of housing 4, and it matches with housing 4 and fairlead 9,12,15 endoporus respectively.Fairlead 9,12,15 is separated into three parts by nonmetal magnetism-isolating loop 10,13 and seam is an integral body, and very high fluid pressure can be born in inside.The endoporus of fairlead 9,12,15 is equipped with the armature 11 that axially movable soft magnetic material is made, and its two ends and yoke 1,6 keep certain clearance, suck for avoiding armature, and the banking stop 8,14 that non-magnet material is made is housed.Output push rod 16 is equipped with at two ends, armature 11 left and right sides, the splicing sleeve form that linear bearing 7,17 or low-friction material are made is housed around the output push rod 16, make the less radial clearance of maintenance between armature 11 and the fairlead 9,12,15, to reduce the friction between armature 11 and the fairlead 9,12,15.Armature 11 radially has aperture 18 or the groove pressure balance at holding armature 11 two ends whereby.
Annular permanent-magnet body 3 both can be integral, and also can be spliced by the polylith permanent magnet, and accompanying drawing 2a has provided the permanent magnet that monolithic permanent magnet and accompanying drawing 2b make with two splicings.
Accompanying drawing 3 has provided the structural representation of the basin shape pole shoe of particular design, and wherein armature 11, yoke 1, fairlead 15,12 are the magnetic conductor that soft magnetic material is made, and magnetism-isolating loop 13 is a non-magnetizer.Magnetism-isolating loop 13 is separated fairlead 15,12, and its leading portion and fairlead 15 have an angle α; For obtaining good output characteristics, angle α should be controlled at 38 °～45 °.Magnetism-isolating loop is divided into two parts with magnetic circuit: main flux Ф m is by armature 11, air gap delta
1Enter yoke, secondary magnetic flux Ф s is by armature 11, air gap delta
2Enter fairlead 15, main flux produces suction F
1, secondary magnetic flux produces suction F
2, the two synthetic power F that obtains horizontal characteristic, each component F
1, F
2And make a concerted effort the F characteristic as shown in Figure 4.
Its operation principle: permanent magnet 3 is at first set up polarizing magnetic field, give two control coils 2,5 input Control current then, this electric current is supplied with by linear constant-current source, after two control coil 2,5 energisings, produce the Distribution of Magnetic Field of equidirectional, i.e. the magnetic field of the two generation be all clockwise or be all counterclockwise to.The main flux path of polarizing magnetic field and controlling magnetic field as shown in phantom in Figure 1.The differential stack of controlling magnetic field and polarizing magnetic field, strengthened in armature 11 1 end magnetic fields, and the other end is weakened, and makes to strengthen armature 11 stressed no longer balances direction to magnetic field and move until producing new balance.When input current polarity is opposite, armature 11 will move to other direction.After feeding the Control current of opposed polarity, owing to adopt fairlead 9,12,15 leading portions of particular design and the basin shape pole shoe that yoke 1,6 is formed, thereby the radially leakage field component of may command armature 11 when moving, the electromagnetic force that armature 11 is subjected to is only proportional with the current value of control coil 2,5 and irrelevant with the stroke of armature 11 relative yokes 1,6 in certain stroke range, therefore just can obtain direction and the corresponding power output of numerical value with Control current on armature 11.Owing to there is the permanent magnetism polar flux to guarantee of the best section work of this electromagnet at magnetization curve, therefore reduce it and used power, eliminated the zero-bit dead band, and made that it is quiet, dynamic characteristic is improved.
