Description

Technical Field

[0001] The utility model relates to the field of linear motors, in particular to a high-speed linear motor module. Background Art

[0002] In some current applications, such as impact test benches for headrests and shuttle mechanisms for looms, the speed requirements are relatively high, even reaching 10m / s, but the current linear motor modules cannot reach such high speeds. Existing linear motor modules are composed of linear motors, rolling guides, reading heads, and grating scales or magnetic scales. Limited by the speed of rolling guides, the speed of commonly used linear motor modules can generally only reach 3m / s. Moreover, the rolling guides will increase wear and friction when running at higher speeds for a long time, which will increase the energy consumption of the linear motor and reduce the service life of the module. Current linear motor modules mostly use linear motors with iron cores as the power part and rolling guides as the guide structure. This method will result in a larger mass to be moved and cannot achieve a higher speed.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a high-speed linear motor module to solve the above problems. Utility Model Content

[0007] The preferred technical solution is: two groups of U-shaped photoelectric sensors corresponding to the head and tail ends of the double-edge V-shaped guide rail are fixed on the base, and a baffle that cooperates with the U-shaped photoelectric sensors is fixed on the slide.
