We are having a 100 HP slip ring induction motor for chilling compressor application which naturally needs a higher starting torque.. We are facing frequent problems in the rotating rotor starter. Is there any alternative arrangement of using a VFD for this arrangement. If so VFD has to be installed in stator or rotor side. Some say that there is a magnetic core available which reactance changes with rotor speed (which is max at start and min at full speed) and has no moving parts which is desirable for a fail safe automated environment. Can anyone suggest me suitable ideas regarding this. With thanks, Veda, India, [email protected]
