FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
2) The formal decisions or agreements of the

CLC IEC/TS 60034-30-2:2021

IEC TS 60034-30-2:2016(E) specifies efficiency classes for variable speed rotating electric machines not covered in IEC 60034-30-1. The classification only covers machines designed for operation with sinusoidal fundamental current that are not designed to be operated direct on-line (grid), for example permanent magnet synchronous machines with and without additional reluctance torque, sinusoidal reluctance synchronous machines and synchronous machines with DC field windings.

Rotating electrical machines - Part 12: Starting performance of single-speed three-phase cage induction motors (IEC 60034-12:2016)
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).
NOTE 1 It is not expected that all manufacturers will produce machines for all eight designs. The selection of any
specific design in accordance with this document will be a matter of agreement between the manufacturer and the
purchaser.
NOTE 2 Designs other than the eight specified may be necessary for particular applications.
NOTE 3 It should be noted that values given in manufacturers' catalogues may include tolerances in accordance
with IEC 60034-1.
NOTE 4 The values tabled for locked rotor apparent power are based on r.m.s. symmetrical steady state locked
rotor currents; at motor switch on there will be a one-half cycle asymmetrical instantaneous peak current which
may range from 1,8 to 2,8 times the steady state locked rotor value. The current peak and decay time are a
function of the motor design and switching angle.

CLC/TS 60034-17:2004

This technical specification deals with the steady-state  operation of cage induction motors within the scope of IEC  60034-12, when fed from converters. It covers the operation  over the whole speed setting range, but does not deal with  starting or transient phenomena. Only indirect thpe converters  are dealt with. This type comprises converters with impressed  direct current in the intermediate circuit (I-conveters) and  converters with impressed d.c. voltage (U-converters), either of  the block type or the pulse controlled type, without restriction  on pulse number, pulse width or pulse frequency. For the  purpose of this technical specification, a converter may  include any type of electronic switching device, for example  transistors (bipolar or MOSfet), IGBTs, thyristors, GTO- thyristors, etc. with analog or digital control electronics.

SIST EN 45510-2-5:2003(Main)
Guide for procurement of power station equipment -- Part 2-5: Electrical equipment - Motors
EN 45510-2-5:2002

This standard gives guidance on writing the technical specification for the procurement of motors for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation of this Guide.
This Guide covers motors within installations primarily concerned with the generation of electrical power. However, as a complete electrical drive system is not defined in this Guide, attention is drawn to the possible additional electrical and mechanical stresses to which the motor may be subjected e.g. by a static AC converter/inverter.  Reference should be made to IEC 60034-17.
The equipment covered by this Guide is defined by its function rather than design type.  Therefore, the guidance to the specification is stated in performance terms rather than being specified by a detailed description of the equipment to be supplied.
This Guide indicates to potential purchasers how their specification should be prepared so that:
- the equipment type and capacity interfaces correctly with other elements of the systems;
- predicted performance is achieved;
- ancillary equipment is properly sized;
- reliability, availability and safety requirements are achieved;
- proper consideration is given to the evaluation process and the quality measures to be  applied.
This Guide does not determine the type of specification (e.g. detailed, performance, functional) or the extent of supply for any given contract which is normally decided on the basis of the purchaser’s project strategy. It does not cover:
- any commercial, contractual or legal issues which are normally in separate parts of an enquiry;
- any allocation of responsibilities which are determined by the contract.
This Guide does not prescribe the arrangement of the documents in the enquiry.
