Abstract

1 Scope

This part of IEC 60034 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;

NOTE 1 Motors with rated power above 2 000 kW are produced in such small numbers and are designed and produced with a focus on achieving an optimum efficiency anyway, even though fulfilling increasingly special requirements that assigning efficiency classes would be an additional effort without the result of any countable energy saving.

• have two, four or six poles;

• are rated for single-speed line-operation;

• are intended for direct-on-line starting at rated or at reduced voltage and rated frequency;

• are constructed to any degree of protection;

• are designed for cooling methods IC411, IC511, IC611, IC01 or IC81W;
