Measuring of Shaft Displacements of an Air Bearing Motor Spindle with GMR-Sensors

Measuring of Shaft Displacements of an Air Bearing Motor Spindle with GMR-Sensors.
In: 13th Symposium Magnetoresistive Sensors and Magnetic Systems, 3rd and 4th March 2015 in Wetzlar, [Conference or Workshop Item]

Abstract

High speed air bearing motor spindles are typical spindle applications in ultra-precision machining machine tools due to the sophisticated requirements of these applica-tions. Accuracy and cost intensive work pieces are the motivations to ensure safe and proper operation conditions. For that reason condition monitoring is useful. A new approach with an innovative sensor type is presented in this paper. GMR-sensors are integrated in an air bear-ing motor spindle to detect shaft displacements and thereby vibrations and other shaft movements that affect the accuracy of ultra-precision machining. The paper describes the implementation of sensor integration into an air bearing motor spindle and also gives a brief view on first tests with the new system.
