Rotating electrical machines - Part 12: Starting performance of single-speed three-phase cage induction motors

IEC 60034-12:2016 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. The main changes with respect to the previous edition are as follows:
 - new design letter E for extended efficiency motors, explanation of all design letters, and description of new designs NE, NEY, HE, and HEY;
 - addition of a reference to IEC 60079-7;
 - addition of a formula to calculate locked rotor current from apparent power.
