Abstract:The force-current factor of radial active magnetic bearing (AMB) is important for the stability and dynamic performance of the magnetic levitation system. For the sake of force-current relationship identification, an experiment method is exhibited in detail. Various static loads can be applied to the rotor in radial direction with a pulley blocks system easily. A 190 kW motor equipped with magnetic bearings and digital control system is tested by the designed measure system. The experiment results are validate… Show more
