SynRM2 motor is IE5 efficiency without rare earth magnets 02 June 2014

Building on the current IE4 'super premium efficiency' standard, ABB's 'ultra-premium efficiency' IE5 SynRM2 technology is claimed to reduce energy losses by a further 20% – and without rare earth magnets.

Presented at Hannover Fair 2014 in Germany, SynRM2 is an upgrade of ABB's award-winning SynRM (synchronous reluctance) motor technology, launched in 2011.

Instead of rare earth permanent magnets, the new motor technology harnesses ferrite magnets, which are more cost effective and easily available.

This results in more economically and ecologically sustainable products.

ABB anticipates most demand for its new, ultra-premium efficiency electric motors to be in the 1—15 kW output range, where plant engineers want flexibility for their motor and drive packages.
