About company
Our company profile is design, manufacture, maintenance service and repair of high-speed electric machines.

For over 10 years Research and Production Company “ERGA” has been developing, manufacturing and providing service of high-speed electric machines (20.000-110.000 rpm).

Research and Production Company "ERGA" traces its history back to 1991 when it focused on production of rare-earth permanent magnets and magnetic systems for special purposes. Nowadays the plant occupies over 25.000 m2, over 10.000 m2 of which are indoor production facilities. In 2007 large-scale re-equipment of production sites was completed, a modern high-capacity line for annual production up to 100 tons of rare-earth permanent magnets was commissioned.

The company's own scientific and technological potential and time-proven partnership relations with the leading research institutes, design organizations and machine-building enterprises enable ERGA to develop effective solutions of complex engineering tasks within short time, which often have no analogues both in Russia and abroad.

WELMA is ERGA's new leading activity, which includes research, design, production, testing of high-speed electric machines.
