Through the acquisition of Motortecnica, Nidec ASI seeks to strengthen its service business and expand in the generators market. In particular, Motortecnica’s capabilities and experience in design, manufacture, repair and remanufacture of electric generators and components, together with Nidec ASI’s worldwide sales network, are expected to help enhance and expand its service business. Furthermore, Motortecnica’s technical capabilities and installed base in power generation applications will allow Nidec ASI to expand in this market and to pursue opportunities for remanufacturing and refurbishing large electric generators.
