In 2017 China traditional industry development space control in the analysis .
First, affected by the downstream, the special elevator growth maintain slight growth
Inverter is constant voltage and frequency of the alternating current (ac), transform device for variable ac voltage and frequency, frequency converter is commonly used in control of ac motor speed or the output torque. Ac motor frequency control of motor speed technology with energy saving, improving technological process, improve product quality and easy to automatic control, and many other advantages.
The working principle of the frequency converter
Inverter industry in our country usually according to the input inverter voltage grade classifying the inverter, generally can be divided into low voltage (380 V), medium voltage (660 V ~ 660 V) and pressure (3 kv) inverter.
Elevator inverter are of low voltage frequency converter in the high-end products, the domestic enterprises after recent years of development, has occupied most of the market share of domestic elevator inverter.
The elevator production declining growth
Second, the general inverter market space is large, growth is expected to continue to ascend
Elevator inverter accounted for about 10% of all low voltage frequency converter market, while domestic manufacturers in the field of elevator inverter occupying most of the market, but other downstream industries, share is still low, there is a huge import substitution market space.
Low voltage frequency converter in domestic industries
Low voltage frequency converter in China market in 2013 brands accounted for
Low voltage frequency converter in our country market dominated by Japanese brand, the early European and American brands enter after a lot of, Europe and the United States with the Japanese brand leading the competition pattern, until around 2000, foreign brand still occupy about 90% market share in China. In recent years, China's manufacturers rely on independent innovation, gradually break through the foreign manufacturer of low voltage frequency converter in the monopoly of the industry, in segments such as elevator industry, has realized the domestic manufacturers to foreign manufacturers. Low-voltage inverter industry in current domestic manufacturers occupy about 25% market share.
Since 2015, a drop in oil prices, oil and gas, mining, metallurgy, cement and other industries (low voltage type inverter project market share of more than 60%) of investment, in China's low-voltage inverter market performance decline. But think as the industry gradually popularization and application of low voltage inverter in the China, along with the industrial upgrading of the industrial automation control level put forward higher requirements, equipment modification, as well as the energy conservation and emissions reduction by a Chinese low-voltage inverter market will remain close to 10% growth.
Low voltage inverter market scale
Import substitution of domestic low voltage frequency converter industry there is a huge market space, the current domestic enterprise, for only about 25%. Same as the elevator inverter industry of high frequency converter, the domestic enterprise market share over 80%, the current domestic enterprises in low voltage frequency converter technology has already surpassed the taiwan-funded enterprises, basically reached the level of Japanese brand, through the involvement of all kinds of low voltage frequency converter downstream market segment, market share of domestic enterprise ascension is only a matter of time, is expected to domestic low-voltage inverter enterprises in recent years, market capacity can reach 23.1% ~ 23.1% increase.
Low voltage frequency converter domestic enterprises market space
Third, the benefit of intelligent manufacturing, servo system business is growing rapidly
Servo system is a kind of motion control components, usually composed of servo drive and servo motor, main task is to, according to the requirement of the control command to amplification, transformation, control the power, control the output of the drive torque, speed and position, the implementation of the object position, orientation and position control. Compared with frequency converter + ordinary motor, servo positioning accuracy is higher, faster response and control to position, performance and higher precision can be said to be a level of frequency converter, is the indispensable important component in intelligent manufacturing, robot.
