About us

Electrodrives, commited to offering the highest quality to our customers

Born from International Electronics S.A. (IES) in 2009, Electrodrives quickly established itself as a manufacturer of excitation systems for hydroelectric plants. On the other hand, Electrodrives provided technical support to the large number of Slip Energy Recovery systems and Liquid Resistance Starters (LRS) installed by IES (SER Drives and LRS).


As leaders in specialized solutions for wound rotor induction motors, we offer a wide variety of products focused on the control and protection of these motors, among them are variable speed drives (SER drives), starters (Liquid Resistance Starters) or our new RotorProtek® starter control and protection system.
