Converteam.
Converteam opened a new rotating machines factory in Yantai, Shandong province. Medium voltage motors and generators will be manufactured there. The company plans also to run a medium voltage drives manufacturing plant in Shanghai and a joint-venture in Wuhan.
More information about the investments and management statements can be found in the company official press release.
Rockwell Automation manufactures three medium voltage drive types – all of them are CSI topology. The main differences between types are: power range, input section configuration, cabinets design – footprint, cooling and control voltage.
