Description
The Dover MAG™ series servo linear actuator offers an integral ironcore direct drive linear servo motor with up to 5 G’s of acceleration and peak force generation of 170 newtons for high acceleration and force generation applications. When smoother motion is required, the stage can be configured with an ironless direct drive linear servo motor for smooth velocity, reduced cogging, and less attractive forces. This makes the Dover MAG™ an ideal candidate for demanding life science, medical, photonics, semiconductor, and hard disk drive inspection and repair positioning applications.
Applications
Our MAG™ series servo linear actuator is great for applications that require high speed motion, or more precise positioning than can be achieved with a screw drive. One application use is for 2G acceleration of a sensor for testing purposes.
Design Features
- No moving cables
