Part of the motors used in Europe must comply with the IE3 performance standard.

Part of the motors used in Europe must comply with the IE3 performance standard.


For people who use electric motors, January 1, 2015, is an important date. In fact, some of these must now meet the IE3 (International Energy Efficiency Class 3) performance standard, requiring changes for all parties involved in the supply chain, from designers to users to integrators. ABB specifies what needs to be done in this article, if practicable, to ensure that the market retains an edge over regulations.


According to directive EC640/2009 and amendment EU4/2009 (see below), any three-phase motor operating directly on the network (fixed wire) and marketed with a rated power range between 7.5 and 375 has been prohibited since January 1, 2015.


Manufacturers of motors

The requirement for the IE3 class of performance marks the point of reference for industrial motor manufacturers and suggests that moving forward, only high-quality materials will be used to manufacture engines. But this isn't always the case. For well-known manufacturers, there is an opportunity to demonstrate real differentiation in the market in other areas of their engine offering, such as dependability, service agreements, and technical support. Additionally, there will be changes in terms of costs. The transition to IE3 will result in a larger investment from manufacturers, although the production processes won't change much, if at all. There will be costs associated with product recycling,


Machinery OEMs

Although the EU MEPS mandate primarily affects engine manufacturers, there are suggestions for the range of engines an OEM can obtain from its usual supplier. Getting a full range of IE3 motors from a single supplier will benefit OEMs, especially those with a significant presence in Europe. OEMs need to be prepared to use IE3 engines in their machines and applications and be clear with their suppliers about what they want or don't want. For example, for heavy torque applications that do not necessarily require lowering the speed, fitting an IE2 motor, and variable speed drive may not be cost-effective.

OEMs should also inspect how the change will affect their logistics and supply chain. IE3 motors can be older and larger than equivalent IE2 motors. Certain overhauls of the product ranges will be essential by integrating new motor sizes, frame height, or resumption of obsessions. However, some manufacturers, such as ABB, have proven their relevance in the origination of motors. If only standard the height of the shaft of an IE3 motor aligns with that of the standard IE2 motor. This promotes faster and more efficient replacement while maintaining the same mechanical structure of the machine. Thus the installation of an IE3 motor is effective.


Fake users

From the point of view of end users, IE3 motors are positioned 10 to 20% above the purchase price of an IE2 motor. But they deliver a payback of that extra cost in just under two years. With a 200 kW 4-pole motor operating 8000 hours/a for an electricity cost of €0.1/kWh, an IE2 motor would represent €169,521 in annual running costs; while the IE3 motor would cost €167,945, providing a saving of €1,576/year or €131/month. The payback period in this case would be well under two years.
