Technical Field

[0002] Linear motors have the characteristics of high speed and high precision. They are widely used driving components in realizing linear motion. General linear motors only generate one-dimensional linear thrust. There are also some tubular linear motors that generate rotational force while generating one-dimensional linear thrust.
[0003] At present, if the motion platform performs vertical two-dimensional motion, two sets of vertical driving linear motor structures are usually used to achieve the vertical two-dimensional thrust required for the two-dimensional motion. For two-dimensional linear motion with a large stroke in one dimension and a small stroke in the perpendicular dimension, conventional linear motors can achieve the thrust required for long-stroke one-dimensional motion, but it is difficult to achieve two vertical thrusts with one motor on this basis.
[0004] Therefore, how to optimize the design of the existing linear motor so that it can generate thrust in a dimension perpendicular to another small stroke and achieve the goal of one motor generating two perpendicular thrusts is a problem that needs to be solved urgently.
