EVS-EN 60034-12:2017

This part of IEC 60034 specifies the parameters for eight designs of starting performance of single-speed three-phase 50 Hz or 60 Hz cage induction motors in accordance with
IEC 60034-1 that:
– have a rated voltage up to 1 000 V;
– are intended for direct-on-line or star-delta starting;
– are rated on the basis of duty type S1;
– are constructed to any degree of protection and explosion protection.
This document also applies to dual voltage motors provided that the flux saturation level is the same for both voltages.
The values of torque, apparent power and current given in this document are limiting values (that is, minimum or maximum without tolerance).
