Abstract
Magnetic bearings work without abrasion, (static) friction and attrition while providing the highest possible travel velocity and acceleration. Consequently magnetic bearings could be ideal guideways for high-speed machine tools. This paper describes a new linear magnetic bearing system suitable for machine tools. Within this contribution the development of a test bench with a linear synchronous direct drive and a magnetic bearing and levitation system is presented. The conjunction of electrical, electronic and mechanical components as parts of a mechatronical system is shown. In addition, measurements of the stiffness are presented to demonstrate the feasibility of the approach.
