Nanjing Suqiang Numerical Control M & E, Co., Ltd., directly under the holding company Nanjing Liyuan Power Magnet (Group) Co., Ltd., specializes in the production of permanent magnet brushless servo motor and driving system, PM-DC Motor. Our company has independent intellectual property right. In August 2002, the permanent magnet brushless servo motor was listed among the national Key New Projects of Products by the State Ministry of Science and Technology. It was also listed among the National Torch Plan Projects in 2003. The company has passed the ISO9001 Quality Management System Authentication in 2002.

The permanent magnet brushless servo motor and DSP digital AC servo driver system is developed together by Nanjing University of Aeronautics and Astronautics, Wuhan Huazhong University of Science and Technology and our company. The driving system is the new generation high precision motion controlled products which is made up of rare earth permanent magnet three phase synchronous motor, rotor position detection and digital servo driver. The motor has the features of high rotating torque, good performance at lower speed, powerful overloading ability, steady speed, high efficiency on low cost, special structured, etc. Its driver adopts the new digital signal processor (DSP), programmable logic device (PLD), intellectual power module (IPM) and the best PID calculating ways which is to realize high frequency SPWM and magnetic-field direction control.  

Our company has the ability of manufacturing over 10,000 motors and drivers every year. The products are under four main catalogs and there are over twenty kinds of them. It is widely used in the fields of CNC, printing and packing, textile, aeronautics and astronautics, military industry, robot and electrical vehicle and so on. The products are mainly supplied to Guangzhou Numerical Controlled Co., Ltd., Shengyang Machine Tool Co., Ltd., Jinan First Machine Tool Co., Ltd., Dalian Machine Tool Co., Ltd., etc. We also export products to American and European countries.
