Beschreibung

This paper presents a new approach for an active damping system, which reduces self-excited chatter vibrations in milling processes. An active damping force is applied by an additional actuator winding, that is integrated into the Stator slots of a motor spindle. Based on an induction machine, the electromagnetic design and the achievable radial forces are examined using transient FEM calculations. The new Approach generates radial forces up to 800 N in the space available for an exemplary 43 kW motor spindle.
