The search is for an adaptable universal-application high-frequency motor spindle that can be kept under dynamic control in various types of machine models allowing briefer set-up times with a simple tool change. The only way to expand or break through the existing limitations is with a spindle design that can be statically and dynamically manipulated. A motor spindle design with an additional magnetic bearing for enhancement of static and dynamic spindle stiffness is presented. The magnetic bearing is located between front and real roller bearings.enmachine toolmotor spindlemagnetic bearingvibrationactive dampingsimulationFEMHSCWerkzeugmaschineMotorspindelMagnetlagerSchwingungaktive Dämpfung620670presentation
