After over 30 years of hard work , the company has grown into a motor manufacturing base with facilities located in Shanghai and Anhui, along with the headquarters in Taizhou. And in 2010, we established our US headquarters ( Power Tech Electric Motors, LLC ) in Overland Park, KS and warehouses in North Carolina, Atlanta. Tens of millions of dollars of electric motors each year are made and shipped from these locations to the North American market.
