U-shaped frame, the movable stand 2 are set in parallel among U-shaped frame, and a pair of stators 10 are provided between the both sides of movable stand 2 and U-shaped frame
With mover 11, fixed mount two inner side be connected respectively by slide rail 9, sliding block 8, spring 7 with movable stand, the brake(-holder) block 4 with rub
Pad 3 is arranged at the side relative with U-shaped frame of movable stand 2.One group of mover on the top of movable stand 2, stator and movable stand bottom
The air gap of one group of mover, stator between specification, material, electrical current size and dynamic, stator is all identical, and therefore, upper and lower two pairs fixed
Son and mover are being powered and electromagnetic force all same during power-off, and under electromagnetic force, object 1 is done steadily along slide rail 9 (Z-direction)
Motion.
Operation principle：
Object 1 can do the motion in horizontally or vertically direction along slide rail 9, so that object 1 does vertical motion along slide rail 9 as an example：
Upper and lower two pairs of stators 10 and mover 11 are powered simultaneously, and electromagnetic force is designated as, a pair of stators on top and the electromagnetism force direction edge of mover
Y-axis negative sense；The stator of bottom and the electromagnetism force direction of mover are positive along Y-axis.The direction of two groups of electromagnetic forces between stator and mover point
It is in opposite direction with the spring force of homonymy, now, the air gap between dynamic, stator is constant, the easy motion of object 1.
Upper and lower two groups of stators and mover power off simultaneously, consistent when all force directions are with being powered, and have, therefore, work as mover, fixed
When being all powered between son, or all powering off, the air gap between dynamic, stator is constant, and movable stand 2 is in intermediate equilibria position.
When one group of stator and the mover power-off on top, when the one group of stator and mover of bottom are powered, because of F1＜ F1', in electromagnetism
