Mechanism of the present invention is because when acting on as the movable permanent magnet iron of motion engine component or Mobile electromagnetic iron as the electromagnetic force that drives or permanent magnetic, opposite pole attracts close, like pole repel away from.Therefore, when driver part maintains static, the electromagnetic force of driver part or permanent magnetic will make the motion engine component magnetic pole deflection on it, this moment, the motion engine component can only produce the motion of the channeling direction of guiding parts owing to be provided with the guiding parts that the motion engine component can only be moved in one direction between driver part and motion engine component.
According to magnetic field interphase interaction principle, when as the magnetic field of the movable permanent magnet iron of motion engine component or Mobile electromagnetic iron when inconsistent as the fixing permanent magnet of driver part or magnetic field that fixed electromagnet produces, if the magnetic field of driver part is enough strong, the motion engine component will deflect to the direction consistent with the driver part magnetic pole or be mobile, until deflection or movement stop on the magnetic direction of the motion engine component position consistent with the magnetic direction of driver part the time.Therefore, if before the driver part excitation, the magnetic direction that the magnetic direction of motion engine component and driver part produce is inconsistent, and the pole orientation of motion engine component will occur to the deflection of driver part pole orientation under electromagnetic field effect so.But, because driver part is fixed, therefore the motion engine component is subject to the constraint of guiding parts, and the magnetic field force that this motion engine component magnetic pole swings can only output on the guiding parts guiding movement direction, thereby it is mobile in the direction of guiding parts guiding to promote the motion engine component.So just can reach a kind of driver part vertical direction and apply magnetic field force to the motion engine component, the motion engine component is in the mobile effect of direction of guiding parts guiding.
And the size of this moving displacement can be by being controlled at the electromagnetic field intensity that the current strength that applies in the fixed electromagnet as driver part namely produces and applying the sense of current or the magnetic field force intensity of fixing permanent magnet is controlled.
In like manner, electromagnet is added reverse current, producing with before rightabout magnetic pole is opposite electromagnetic force, move to the direction near driver part away from extremely will being attracted of motion engine component of driver part so, simultaneously, be adsorbed on extremely will being subjected to repulsion of motion engine component of driver part end face before and move to the direction away from driver part.Like this, by control driver part magnetic field intensity, the motion engine component is occured and opposite before horizontal movement, until stop during magnetic pole coincidence position.
Like this, process is to applying forward and reverse electric current or the magnetic field of some strength as driver part, and in the horizontal direction reciprocating motion can occur the motion engine component.
