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 IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60034-12 has been prepared by IEC technical committee 2:
Rotating machinery.
This second edition cancels and replaces the first edition published in 1980, its Amendment 1
(1992) and its Amendment 2 (1995). This second edition constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
2/1187/FDIS 2/1199/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged until
2005. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

ROTATING ELECTRICAL MACHINES –
Part 12: Starting performance of single-speed
three-phase cage induction motors
1 Scope
This International standard specifies the parameters for four 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.
The standard also applies to dual voltage motors provided that the flux saturation level is the
same for both voltages and to motors having type of protection 'e – increased safety' with
temperature classes T1 to T3 complying with IEC 60079-0 and IEC 60079-7
NOTE 1 It is not expected that all manufacturers will produce machines for all four designs. The selection of any
specific design in accordance with this standard will be a matter of agreement between the manufacturer and the
purchaser.
NOTE 2 Designs other than the four specified may be necessary for particular applications.
NOTE 3 The values of torque and apparent power given in this standard are limiting values (that is, minimum or
maximum
