ABB’s new SynRM² motor technology will deliver IE5 efficiency without rare earth magnets

2014-04-03 - New Ultra Premium Efficiency IE5 motor technology takes today’s IE4 current standard a step further.
ABB, the leading power and automation technology group, is taking motor efficiency to the next level. Building upon the current IE4 Super Premium Efficiency standard, ABB’s innovative IE5 SynRM2 technology will reduce energy losses by an additional 20 percent.

The new SynRM2 is an upgrade of ABB’s award-winning SynRM (synchronous reluctance) motor technology launched in 2011. It strengthens ABB’s motors and drives technology portfolio particularly in markets where customers require the highest efficiency.

A unique feature of ABB’s latest SynRM2 motors is that they do not utilize rare earth permanent magnets. Instead they use ferrite magnets, which are more cost effective and easily available. This results in more economically and ecologically sustainable products.

The largest business potential for the new motors is in the 1-15 kW output range, and among OEM customers who require motor and drive packages which can be flexibly configured for optimum performance in a variety of specific application needs.

ABB will presenting the new SynRM2 motor technology at the Hanover Fair, April 7-11, 2014 in Germany.

ABB ( is a leader in power and automation technologies that enable utility and industry customers to improve their performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 150,000 people.
