Sym-lstrom – IKME

The goal of this project is to find an economical and effective solution against ball-bearing failures caused by bearing currents in traction drive synchronous motors. The mechanisms of bearing currents in synchronous motors supplied by frequency converters will be identified and verified by measurements. Remedial actions will be developed for synchronous motors and checked for their effectiveness. Afterwards, the developed actions will be evaluated from a technical and economic point of view and verified by measurements.
