Medium & High Voltage Motors

With the acquisition of Ansaldo Sistemi Industriali SpA in 2013, Nidec became one of the few manufacturers in the world that can claim more than 150 years in the design and manufacture of MV and HV electric motors for industrial applications, up to 60 MW. Our engineering team can support new product development, revampings and retrofits including reverse engineering for older brands that no longer exist on the market.
