Servo drive system, usually by the servo motor and servo drive components, will use a variety of motor torque and force, directly or indirectly drive the machine body to get a variety of machine movement. In addition to speed and torque control, the servo system can also be accurate, fast and stable position control.

Common servo motor

The servo motor is widely used in injection molding machines, CNC lathes, military equipment, packaging machinery, textile machinery, ATM machines, inkjet printers, printing machines, etc., for applications requiring smooth running, low noise, quick response, long service life and high output torque. Computer peripherals and mass storage devices, precision instruments, industrial control systems, office automation, robotics, and other fields.

In the field of robots, servo motors play an important role. In general, the servo motor of the robot is used to convert motion commands issued by the brain of the robot into moving parts. In this way, the servo motor can be used to describe the position of the servo motor in the robot.

Status: 80% market share by foreign enterprises occupy

At present, the domestic high-end market is dominated by foreign brands occupy about 80% of the market share, and mainly from Japan and Europe and the United States. Among them, Japanese products to about 50% of the market share of the top, the famous brands include Panasonic, Mitsubishi Electric, Yaskawa, Sanyo, Fuji and so on.

Domestic servo market share about the distribution

Now, the domestic market, most of the foreign brands appear in Japan, Europe and the United States and Taiwan.

Japan servo motor brand - Panasonic, Mitsubishi, Yaskawa

Matsushita Electric Works

Panasonic servo motor sales in the Chinese market is very high, the price is generally higher than the domestic servo motor 1000 or so, but the price of imported foreign servo motor brand is quite cheap, and some even lower than the series of servo motors, quality in the short term . Mitsubishi Electric Corporation

Mitsubishi Electric is divided into two series, including a lower price, relatively high cost; while the other is a solid quality, but generally higher prices of Mitsubishi Electric.

Yasukawa Electric

YASAWA servo motor, also known as YASKAWA YASKAWA servo motor, the origin of Japan, in Shenyang, Shanghai, China also has a factory, is to make the object position, orientation, state output, such as controlled volume, to follow the input target value of any changes Automatic Control System.

Why the Japanese brand will account for 50% of the share? The main reason is the Japanese servo motor technology and performance levels in line with the needs of Chinese users, cost-effective, so a stable and continuous customer base, so small and medium OEM market Especially with a monopoly advantage.

Europe and the United States servo motor brand - Rockwell, Siemens, SEW

Rockwell

Rockwell is an American motor brand that has the advantage of accelerating system design, higher performance, better predictability and ability to prevent downtime, and faster response to manufacturing process changes.

Siemens

Siemens is the common German electrical brand, Siemens servo motor known.

SEW

SEW is a British motor brand in the country relative to other foreign motor brand is relatively rare, the share is slightly lower, but its excellent quality and stable working condition is far more than domestic brands, but the spread is very large.

Big brands occupy a relatively balanced market share

The future: from 25% growth, China has the potential

If the development phase of China's servo motor to do a simple inventory, there will be budding stage, the initial stage of development and domestic substitution phase of three stages.

The embryonic stage is from 1995 to 2005, servo system research strength is mainly concentrated in universities, research institutes, military, aerospace satellites for the application of the product remain in the research, trial stage. And 2005-2010, is the initial stage of development, this time, talent constantly enrich, domestic brands continue to be born, product performance, market acceptance continues to increase, and gradually applied in the field of civilian products.

Since 2010, there are a lot of manufacturers to increase the introduction of the second generation of servo products, performance, significantly increased market acceptance increased. Now, in the machine tools, robots and other automated equipment import substitution is accelerating in progress. Some experts believe that the next five years, China's servo system industry to benefit from the impact of industrial upgrading, will maintain rapid growth, domestic alternative space is still great.

Three stages of servo motor development in China

From the development stage can also be seen to cause domestic servo motor brand behind the reasons: First, the domestic servo motor industry basic research less, production enterprises lack of intellectual property awareness, apply for less, and most of the applicants for the universities and research institutes , The R & D technology into a low proportion of production, seriously affecting its industrial progress. Second, the domestic servo motor manufacturers started late, lack of technical reserves, innovation capacity is weak, while less R & D investment, resulting in slow technological progress, low level of localization, less competitive.

Third, the domestic servo motor manufacturers to low-cost as the main competitive strategy, sacrificing the product profits for the high value-added products, inadequate investment, product technology improvements and slow progress in the introduction of new products.

At the same time, the domestic servo motor policy support less downstream applications. While the servo motor precision is high, its technical difficulty is bigger and so on the reason also caused the domestic servo electrical machinery brand market share to be smaller.

In summary, is a no interest-driven, and second, the industry believes that the study cost is not high.

Of course, the development to the present, there are a number of domestic servo motor brand to achieve a breakthrough.

AC servo system market scale

Taiwan Department of servo motor brand - TECO, Delta

East yuan motor

TECO produces all kinds of motors in accordance with international standards, including NEMA motors, explosion-proof motors, IE3 motors, IE4 motors, and other types of motors with a power range from 1 / 4HP to 100000HP. Yuan motor.

Delta of the motor

Delta is the best-selling brand of servo motors in Taiwan, because of its more stable quality, and relative to Europe and the United States at a lower price to the most cost-effective use of the servo motor when the choice.

Domestic servo motor brand - Central China NC, Guangzhou NC

Approach the past few years, the development of domestic brand servo system is very rapid, access to a certain market recognition, more representative of the main enterprises in Central China CNC, CNC and other Guangzhou. There are some large enterprises into the servo system industry, the British Witten, Kymmene, Andy and so on.

Domestic servo system in technology and performance also has a wide gap with foreign products, product quality stability is not enough. However, low prices, and better after-sales service, so it can occupy a certain market.
