IEC 60034-30-1:2025 specifies efficiency classes for single-speed electric motors that are rated in accordance with IEC 60034‑1 or IEC 60079‑0 and are rated for operation on a sinusoidal either 50 Hz or 60 Hz, or both voltage supply.
The motors within this document:
- have a rated power PN from 0,12 kW to 1 000 kW;
- have a rated voltage UN from 50 V up to and including 1 000 V;
- have 2, 4, 6 or 8 poles;
- are capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature class;
NOTE 1 Most motors covered by this document are rated for duty type S1 (continuous duty). However, some motors that are rated for other duty cycles are still capable of continuous operation at their rated power, and these motors are also covered by this document.
- are marked with any ambient temperature within the range of –30 °C to +60 °C;
NOTE 2 The rated efficiency and efficiency classes are based on 25 °C ambient temperature in accordance with IEC 60034‑2‑1.
NOTE 3 Motors exclusively rated for temperatures outside the range – 30 °C and +60 °C are considered to be of special construction and are consequently excluded from this document.
NOTE 4 Smoke extraction motors with a temperature class of up to and including 400 °C are covered by this document.
- are marked with an altitude up to 4 000 m above sea level.
NOTE 5 The rated efficiency and efficiency class are based on a rating for altitudes up to 1 000 m above sea level.
This document establishes a set of nominal efficiency values based on supply frequency, number of poles and motor output power. No distinction is made between motor technologies, supply voltage or motors with increased insulation designed specifically for converter operation even though not all motor technologies are capable of reaching the higher efficiency classes (see Table 1). This makes different motor technologies fully comparable with respect to their energy efficiency potential.
The efficiency of power-drive systems is not covered by this document. Motor losses due to harmonic content of the supply voltage, losses in cables, filters and frequency-converters, are not covered.
Motors with flanges, feet or shafts with mechanical dimensions different from IEC 60072‑1 are covered by this document.
Geared motors are covered by this document including those incorporating non-standard shafts and flanges.
This document does not apply to the following:
- Single-speed motors with 10 or more poles or multi-speed motors.
- Motors with mechanical commutators (such as DC motors).
- Motors completely integrated into a machine (for example pump, fan and compressor) that cannot be practically tested separately from the machine even with provision of a temporary end-shield and drive-end bearing. This means the motor: a) shares common components (apart from connectors such as bolts) with the driven unit (for example, a shaft or housing) and b) is not designed in such a way as to enable the motor to be separated from the driven unit as an entire motor that can operate independently of the driven unit. That is, for a motor to be excluded from this document, the process of separation shall render the motor inoperative.
- Totally enclosed air-over machines (TEAO, IC418), i.e. totally enclosed frame-surface cooled machines intended for exterior cooling by a ventilating means external to the machine. Efficiency testing of such motors can be performed with the fan removed and the cooling provided by an external blower with a similar airflow rate as the original fan.
- Motors with integrated frequency converters (compact drives) when the motor cannot be tested separately from the converter. Energy efficiency classification of compact drives is based on the complete product (PDS, ie. Power Drive System) and is defined in IEC 61800‑9‑2.
NOTE 6 A motor is not excluded when the motor and frequency-converter can be separated, and the motor can be tested independently of th

IEC 60072-2: 2025 covers the majority of rotating electrical machines for industrial purposes within the dimension range and output powers: - Foot-mounted: shaft heights: 355 mm to 1 000 mm. - Flange-mounted: pitch circle diameter of flange: 1 180 mm to 2 360 mm. It gives tables of fixing dimensions, shaft extension dimensions and their tolerances. However, the variety of construction and the wide range of applications for the large machines with shaft heights above 315 mm have led to the establishment of a relatively large number of values for the dimension in order to cover all possible constructions. Owing to this, the present part covers a wider range than IEC 60072-1 within which range values suitable for all designs or for a more detailed standardization can be chosen. NOTE The mounting dimensions given in this document for shaft heights 355 mm and 400 mm have been chosen from values given in IEC 60072-1. This second edition cancels and replaces the first edition published in 1990. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) complete revision on the basis of IEC 60072-1; b) additional tolerances and measurements for shafts and flanges (DIN SPEC 42955).
