What is Soft Starters for Kaeser Compressors about?

Soft-starting electric motors aims to limit high starting current. Measurements showed that soft starters do not reduce current draw as much as expected for rotary screw compressors due to their high breakaway and run-up torque. Testing a 160 kW rotary screw compressor revealed even higher starting current with a soft starter compared to a star-delta starter. While soft starters reduce mechanical stress and avoid star-delta switching peaks, they require supplying the same or higher power than star-delta sta
