Major Topics of next edition of IEC 60034-2-1

Document structure has been revised and simplified:

Chapter 3: Terms and definitions

Chapter 4: Symbols and abbreviated termsChapter 5: Basic requirements

Chapter 6: Test methods induction machines

Chapter 7: Test methods synchronous machines

Chapter 8: Test methods DC machines

Flow-charts have been introduced to clarify the precise order ofindividual tests

Preferred testing methods and other testing methods are now

clearly referenced and given in separate tables.

Accuracy of frequency stability raised from 0,3% to 0,1%

Number of recorded digits for digital instruments is required

Accuracy of instrument transformers raised from 0,3% to 0,2%

Speed measurement accuracy raised from 1 to 0,1 rpm.Martin Doppelbauer

Testing methods for induction machines

This standard defines three different preferred methods with low uncertainty within the given range of

application, Table 2A. The specific method to be used depends on the type or rating of the machine under

test:

Method 2-1-1A: Direct measurement of input and output power by using a torquemeter ordynamometer. To be applied for all single phase machines.

Method 2-1-1B: Summation of separate losses. Additional load loss determined by the method of

residual loss. To be applied for all three phase machines with rated output power up to 2 MW.

Method 2-1-1C: Summation of separate losses. Additional load loss determined by the method of

assigned value. To be applied for all three phase machines with rated output power greater 2 MW.

Testing methods for induction machines

These test methods may be used for any test, i.e. field-tests, customer-specific acceptance tests or

routine-tests.

In addition, preferred methods of Table 2A may also be used outside the power range identified in

Table 2A.

Further changes

8-pole motors have been added;

High voltage motors still notcovered;

Definition of type of operation improved to close loop holes: ... capable ofcontinuous operation at their rated power with a temperature rise within the specified

insulation temperature class;

Definition of ambient temperature improved to close loop holes: ... marked

with any ambient temperature within the range of 20 C up to + 60 C;

Definition of rated altitude improved to close loop holes: marked with an

altitude up to 4 000 m above sea level.

Definition of brake motors improved to close loop holes: ... excluded are brake

motors, when the brake is an integral part of the inner motor construction and

can neither be removed nor supplied by a separate power source during testing

of the motor efficiency

(Note: Brake coil losses are disregarded in efficiency determination)

Next level of technology: IE5

IE 5 ?

The levels of the IE5 efficiency class are envisaged to be incorporated into the next edition

of this standard. It is the goal to reduce the losses of IE5 by some 20% relative to IE4. Motortechnologies for IE5 are currently not well developed and not commercially available.

Further energy-efficiency optimizations will have to focus on improved system efficiency

throughout the entire operating load cycle including all system-losses (converter, filter, cables,

motor etc.) see EN 52800.
