The autonomy of VFD (Variable-frequency Drive) needs to be improved

The development of Chinese VFD (Variable-frequency Drive) industry is in a deformed state. In addition to some fields that require Tianjin's low-end VFD (Variable-frequency Drive) and professional segmentation to meet the needs of Chinese domestic production, The localization rate of medium and high-end VFD (Variable-frequency Drive) products in China is still at a relatively low level, and further improvement is urgently needed.

The development of Chinese VFD (Variable-frequency Drive) industry is dependent on the infiltration of foreign brands. Although Chinese domestic VFD (Variable-frequency Drive) companies have developed rapidly in recent years, in the face of fierce market competition, the brand quality is excellent. The market share of Chinese domestic VFD (Variable-frequency Drive) companies is still stretched.

Chinese domestic VFD (Variable-frequency Drive) products have a certain gap in technical content compared with foreign products of the same type. Chinese domestic VFD (Variable-frequency Drive) industry develops late, there is no more technology accumulation, and the establishment time is short ; The low-end market has fierce competition and low profits, resulting in low profit scale of enterprises, lack of funds, and limited investment in research and development, which makes Chinese domestic VFD (Variable-frequency Drive) enterprises restricted in technology research and development, enterprise production capacity, and product marketing. It restricts the development of domestic VFD (Variable-frequency Drive) enterprises in China.

In addition, because many domestic VFD (Variable-frequency Drive) enterprises in China are in the initial stage of competition, with the same technology and technology, some manufacturers transfer the contradiction of market competition to the reduction of manufacturing costs.

In the VFD (Variable-frequency Drive) industry, the development of Chinese VFD (Variable-frequency Drive) industry has grown through three stages of imitation, introduction and independent research and development. But at present, only some excellent enterprises in China have self-developed high-end technologies, and generally domestic VFD (Variable-frequency Drive) enterprises in China are still in the primary competition state of the first and second stages.

At present, the growth rate of VFD (Variable-frequency Drive) industry reached 27.27% in 2010, mainly because the supply of medium and low-voltage VFD (Variable-frequency Drive) was in short supply last year, and the growth rate reached 30%. ) high growth rate, the high-voltage VFD (Variable-frequency Drive) growth rate is 22.7%. High-voltage VFD (Variable-frequency Drive) competition intensifies, and prices continue to show a downward trend. After calculation, the VFD (Variable-frequency Drive) industry will continue to maintain a high growth rate of about 20% in the future.

High-voltage VFD (Variable-frequency Drive) accounts for about 30% of the market share, medium and low-voltage VFD (Variable-frequency Drive) accounts for about 70% of the market share, and high-voltage VFD (Variable-frequency Drive) Chinese domestic brands have a market share of 80%. The space for import substitution is quite small. Medium and low voltage VFDs (Variable-frequency Drive) are all concentrated in low-end products, and the competition is fierce. The market share of domestic brands in China is only about 30%.

The rapid development of the VFD (Variable-frequency Drive) industry can be summed up in several points. The first is the rapid growth and promotion of local advantageous enterprises. The VFD (Variable-frequency Drive) industry is advancing rapidly; in addition, the VFD (Variable-frequency Drive) industry is affected by technology, which makes the entry threshold for new companies higher, and VFD (Variable-frequency Drive) companies need continuous advancement in order to seek development Independent innovation of product technology has ensured the benign development and healthy growth of the VFD (Variable-frequency Drive) market; in addition, VFD (Variable-frequency Drive) companies have also actively introduced diversified strategies such as capital investment and developing new markets.
