Abstract
Permanent-magnet push-pull electromagnet.Existing electrical equipment tractive electromagnet all is with iron core, and volume, weight, power consumption, noise are big, and it is big that armature is subjected to the single-way counter-force spring action to produce vibrating noise, and the life-span is short.This electromagnet is provided with the parallel permanent magnet opposed of two homopolarities, and an AC line circle is set between two like poles, and after the energising, two magnetic poles can produce one to coil respectively and push away an active force that draws, and do relative motion in guiding mechanism effect lower coil and permanent magnet; Can do the location of various ways after the outage.This electromagnet has that volume weight is little, noise is little, power consumption less, many, the reliable in action of function, life-span advantages such as grow.
Description
The invention belongs to the tractive electromagnet of using on the electrical equipment.
Traditional tractive electromagnet of using on the electrical equipment is mainly by iron core, coil, armature, the compositions such as reaction spring that are connected with armature, this class electromagnet is because existence unshakable in one's determination, volume weight increases, operation noise pollution environment, and its relative movement part armature has only the single force direction that is subjected to iron core, so resetting after the outage also can only be leaned on the effect of single-way counter-force spring, not only manner of execution is single, and the single-way counter-force spring can cause judder when discharging armature, produce noise, can reduce useful life on the one hand, simultaneously, overcome the reaction spring effect and also can increase operand power.
The present invention is intended to overcome above-mentioned deficiency, provides a kind of nothing unshakable in one's determination, thereby reduces the tractive electromagnet of weight, volume, power consumption and noise, and this electromagnet can be cancelled spring or adopt the two-way reset spring to reduce vibration, increases the service life.
The technical solution that realizes above-mentioned purpose is: this electromagnet comprises shell, dc coil, it is characterized in that: it also comprises parallel two permanent magnets that are oppositely arranged of homopolarity in the enclosure, between this two like pole, aforesaid dc coil is set, the hub of a spool axis vertically passes two parallel magnetic poles, keep certain distance between coil end and the magnetic pole, this electromagnet also is provided with can make the keep relative stability positioning element of position and when coil and permanent magnet are done relative motion of coil and magnetic pole behind the coil blackout, can control coil or permanent magnet along and the reciprocating guiding mechanism of coil axis equidirectional.
The operation principle of this electromagnet is: when switching on to dc coil, coil two ends one end is the N utmost point, one end is the S utmost point, because two pole polarity that are oppositely arranged are identical, so be same polarity near its one of coil-end, one is heteropolarity, just inhale mutually for one, one is repelled each other, draw coil on the direction identical, doing relative motion under the control of guiding mechanism even one pushes away one with coil axis with magnetic pole, thereby drive electric appliance switch contact or other parts and finish actions such as corresponding switch, change the sense of current, can change the direction of coil and magnetic pole relative motion, during outage, can make coil and magnetic pole keep required relative position according to different positioners is set.
This permanent-magnet push-pull electromagnet is simple in structure, can cancel iron core, though the magnetic field that energising back coil itself produces than the coil that adds iron core a little less than, but under the effect of the relative magnetic pole of the permanent magnet same sex, can produce one and push away a bigger composite force that draws, make coil and magnetic pole do relative motion, use it for various circuit breakers, contactor etc., can reduce weight, volume and noise, reliable in action is saved the energy.And traditional electrical magnet can only lean on the single-way counter-force spring to the armature location that resets, locate mode is single, this electromagnet is two relative permanent magnets of homopolarity by the synergistic parts of electromagnetic force and is clipped in dc coil between them, the outage back can be by the ferrimagnet of a certain poles attract as long as be provided with at the coil diverse location like this, can easily realize moving component is done the selection of several form locate modes from both direction, and owing to can remove the single-way counter-force spring, so can reduce vibration and operand power, increase the service life, and reliable in action.
