Motion Control

The last 20 years have seen precision amplifiers used for positioning and velocity control make major strides in power output, size, and control features. Applications such as laboratory automation, semiconductor equipment, and scientific automation make use of high-end amplifier capabilities such as field-oriented control. The cost of electronics is coming down to a point where even industries identified with basic motion needs now consider using high-end features, particularly where smoothness, motor efficiency, and top speed matter....More

The 2013 Linear Motion Catalog and Design Guide contains new product sections, including Idea encoder-ready stepper motor controllers, BGS linear rail systems, and a linear-rail application checklist. The 250+-page catalog and guide illustrates a wide range of products for use in linear-motion assemblies....More

Bellows couplings transmit power from 0.5 to more than 100,000 Nm at speeds from 0 to 100,000 rpm. They offer distinct advantages, but replacing other coupling types with them requires solid understanding of their operation....More
