Rotating electrical machines - Part 30-3: Efficiency classes of high voltage AC motors (IE-code)

IEC 60034-30-3:2024 specifies efficiency classes for fixed-speed three-phase high-voltage cage induction motors in accordance with IEC 60034-1 that

  • have a rated voltage exceeding 1 000 V, but not exceeding 11 kV;
  • have a rated power from 200 kW to 2 000 kW;

This document provides the global harmonization of energy-efficiency classes of three-phase cage induction motors with rated voltage above 1 000 V that are rated for direct online starting and fixed-speed operation at a 50 Hz or 60 Hz supply with sinusoidal voltage.
