优秀的结构
Designed for applications requiring exceptional smoothness of travel, the ALS2200 utilizes precision crossed-roller bearings. Since there are no recirculating elements, vibration throughout travel is minimized resulting in outstanding velocity stability. Machined from a stress-relieved special aluminum-alloy extruded base, the ALS2200 has excellent stiffness and long-term stability.
直线电机驱动
The ALS2200 utilizes an ironless core so it is a cog-free design. The lack of cogging enables extremely tight velocity control, as well as superior contour motion profiles. As with all of Aerotech’s ALS series stages, there is zero backlash, no windup, zero friction and outstanding system responsiveness.
出色的分辨率
Many applications require outstanding step-to-step resolution. The ALS2200 meets this demand with a resolution of 3 nm when coupled with Aerotech control products. The direct-drive linear motor allows the ALS2200 to make precise, small resolution steps that are particularly important in alignment applications where step accuracy is critical.
封闭式设计
To protect the stage from debris and particulates, the ALS2200 incorporates a full-length metal waycover and advanced sealing system. Tensioned side straps are used in lieu of bellows which are difficult to keep clean and increase the overall stage profile. The straps are in a vertical orientation that prevents debris from accumulating and the straps are under constant tension to create a tight seal.
安装方便
The tabletop of the ALS2200 is treated with a protective, scratch-resistant, Teflon®-impregnated hardcoat (Rockwell 62 hardness). All of the tabletop mounting holes utilize stainless-steel Helicoil® inserts to protect against thread wear. The base mounting holes are located outboard of the stage, which allows the stage to be mounted without removing the hardcover.
The ALS2200 utilizes a moving magnet design in the linear-motor drive mechanism. As a result, there are no moving cables and therefore no cable management system, simplifying system interconnection.
