IEC 60034-12:1980 ED1

Rotating electrical machines - Part 12: Starting performance of single-speed three-phase cage induction motors for voltages up to and including 660 V IEC 60034-12:1980 ED1

Publication date:   Jan 1, 1980

Scope

Specifies four standard designs of starting performance for three-phase motors, from 0.4 kW up to 630 kW for direct on-line or star-delta starting and rated on the basis of duty-type S-1 (maximum continuous rating). Also covers dual voltage motors in so far as the flux saturation level is the same for both voltages.
