China variable frequency drive development history

Compared with USA, Japan and European countries, Chinese variable frequency drive's technology is relatively backward. In early 1980s, Dalian Motor Factory introduction of Japan's Toshiba variable frequency drive technologies. Followed by Japan Sanken, Fuji Electric Corporation of Japanese variable frequency drives promoting in China for motor speed controls to break the monopoly of the DC speed start AC motor speed regulation era. In 1996, the former Ministry of Machinery and other four ministries recommended domestic 29 33 manufacturers specifications variable frequency drives, but the majority of local enterprises by the technical, financial and institutional constraints, slow development, it is difficult to form a protest situation against foreign brands.

With the variable frequency drive products widely used in developed countries, the late 1980s, as the representative of the Japanese brands, foreign brands began to rush in mainland China, which is the beginning of the variable frequency drive industry in China. After more than 20 years of promotion and use of this product, VFD drive has been recognized by the majority of business users, foreign brands from Sanken, the Fuji brand development to more than 40, while the emergence of nearly one hundred domestic brands, brands the total number of to more than 140. On the whole, although the large number of domestic brands, but the vast majority of production and sales are very small, due to weak overall competitiveness.

Since the 21st century, China variable frequency drive industry is highly fission. Many foreign brands begin to set up factories in China, the implementation of the localization of business. See Appendix major foreign brands in the Chinese mainland investment. On the other hand, the original domestic brands personnel and funds continue separation, the establishment of a number of enterprises, mainly concentrated in coastal areas such as Guangdong, Zhejiang, Shandong, Shanghai and other regions. Under the support and encouragement of the national macro-policy, domestic variable frequency drive brands in recent years there have been a few dominant companies, its production scale and product performance has been greatly improved. Although not yet have the strength to round competition and international top brands such as Siemens, ABB, compared to Japan, Taiwan, South Korea and other brands in some product segments and market shows a certain competitive advantages, gradually expand the market share, domestic variable frequency drive market, the competitive landscape has been significantly changed.
