Conformity with Community Directives
The standard electric motors are in conformity with the following Directives:
• Low Voltage Directive 2014/35/UE;
• Directive EMC 2014/30/UE regarding intrinsic characteristics in relation to emissions and levels of immunity;
• Directive RoHS 2015/863/UE relating to the prohibition or limitation of use of noxious substances in electrical and
electronic equipment;
• ErP Directive 2009/125 / EC regarding eco-compatible design and its implementing regulation n ° 640/2009.
The manufacturer of the machine is exclusively responsible for the conformity with the Machinery Directive and
EMC Directive of a complete installation. Electric motors may not be commissioned until the machines to which
they are coupled have themselves been declared conforming with the Machinery Directive (Certicate of Incorpo-
ration – Directive 2006/42/CE).

Remarkable latest innovations in above mentioned standards are:
• IEC 60034-2-1 (standard methods for determining losses and eciency from tests) and
• IEC 60034-30 (eciency classes of single-speed, three-phase cage-induction motors; IE-code).
By IEC 60034-2-1 an improved procedure for testing of the eciency is described. In general the nominal eciency
evaluated by this method is slightly lower than the value based on the formerly used procedure. IEC 60034-30 de-
nes classes of eciency for standard motors (“International Eciency”):
“IE1”(Standard Eciency),
“IE2”(High Eciency),
“IE3”(Premium Eciency) and
“IE4”(Super Premium eciency).
These eciency class denitions demand a minimum eciency value depending on power rating and pole num-
ber of the motor. (This classication replaces the formerly used eciency class denitions like e.g. “e1”.) The mo-
tors in this catalogue (IE3) full or override these minimum levels.
The European Union published on 25 October 2019 the result of the revision of the Commission Regulation (EC)
640/2009 for electric motors. The new Commission Regulation (EU) 2019/1781 will require minimum requirements
for a wider scope of motors (0.12 kW - 1000 kW), will also include 8-pole motors and will abolish the former requi-
rement of an IE2 motor plus a converter instead of IE3. Also, maximum losses for converters between 0.12 kW and
1000 kW at IE2 are requested. From 2023, IE4 will be required for motors between 75 kW and 200 kW.
• 01/01 2017: eciency class IE3 for all motors from 0,75 kW up to 375 kW (or IE2 if inverter operated).
• 01/07/2021: eciency class IE3 for all motors from 0,75 kW up to 1000 kW
• 01/07/2021: eciency class IE2 for all motors from 0,12 kW up to 0,55 kW
• 01/07/2023: eciency class IE4 for all motors from 75 kW up to 200 kW in 2,4,6 pole

1 Eciency (IE) classes for single speed electric motors according to IEC 60034-30-1
1.2 Basics, terms and denitions
Induction machines are the commonly most used motor type for general drive applications. They are extremely
durable and robust and provide an economic drive solution, even under severe environmental conditions. They
can be used for direct line operation (xed speed) or in combination with a frequency inverter (variable speed drive
system). They are available in a lot of varieties. Some typical characteristics are listed below:
1.2.1 Power rating
The power rating of electrical motors refers to the mechanical shaft output power (in opposite: for electrical
generators the rating refers to the electrical power at the terminals). Within the IEC standard range (up to 315 kW)
standardized values for the rating are dened (e.g. 37 kW, 45 kW etc.).
1.2.2 Frame size
The frame size is dened as the distance [mm] between the mounting level and the centre of the shaft (in case
of oor mounted arrangement; accordingly a denition is stated for ange mounted arrangement). Standard
values for the frame sizes are dened for the IEC standard range (e.g. frame size 200, 225 etc.). In addition a xed
coordination between power rating and frame size is dened in IEC 60072-1. Within a dened frame size several
types can be designed with dierent lengths.
1.2.3 Mounting arrangement
Rotating electrical machines can be delivered in a large variety of possible physical arrangements. In IEC 60034-7
the construction and arrangement is classied, (IM code as e.g.“IM B3”). Mechanical interface dimensions and their
tolerances are standardized for each frame size. Table of some typical arrangements:
