Around two decades ago, active magnetic bearings (AMB) were introduced into O&G-applications (Oil & Gas- applications), but never gained any relevant market share in large turbomachinery. This paper discusses how standard drive technology from machine tool applications can be used to control AMB systems and how the integrated data acquisition functions simplify the commissioning process. As a proof of the concept, results of prototype testing with a 5 MW induction motor are presented.
