Machine component test unit has contactless actuators with contactless sensors including actuator air gap magnetic flux sensors

摘要

A machine component (7) test unit has contactless sensors (11, 12, 13) measuring vibrations induced by electromagnetic or electrodynamic force or motion in magnetic bearing actuators (4, 5, 6) and contactless sensors (8, 9, 10) measuring the magnetic flux in the actuator air gap.
