ADTECH QS7 Series AC Servo Driver(New Products)

  ADTECH QS7 series AC servo driver is a new generation of product our company launched at year of 2012 and is the result of optimization and improvement based on our QS6 series servo driver. It keeps the good quality of QS6 series servo motor driver and is more stable and convenient for use.
QS7 servo motor driver has FPGA software platform with high-performance, the best wiring design and profound understanding about space vector control algorithm (SVPWM), application with the best wiring design. Our company’s servo driver has reached a new height with QS7 after experiencing 7-years and 3-gernertaion’s steeling. It can easily solve shaking, interference and other industrial site issues with its built-in various smoothing, filtering, instruct-following algorithm. It has subsection control mode switching, electronic gear ration, MODBUS multi-axis linkage and other functions. So it can be flexibly used in all kinds of situations and meet needs of diversity. The function of newly added automatic moment of inertia identification simplify the setting steps and it only need a few step to get good results.

Below its characteristics:

1. more stable, rich and complete data

2. newly increased 485 communication function , more convenient and reliable in connection with upper computer software and controller

3. single-power supply (QS7AA050M2 is double-power supply) , simplify power supply, convenient to wiring and save cost

4. rich specification and model, rated power covers from 100W to 3.8KW, can meet needs of various industries

5. with Intelligent power module device; overall optimization in compact structure, wiring, port; strong anti-interference ability

6. parameters setting, mechanical size, encoder port, power supply port is completely compatible with QS6 series, give convenience to old customer to update

7. newly increased automatic inertia indentification to make setting more convenient.

This is new servo drivers products from ADTECH, we except to your attention. 

Chinese Market for Low Voltage AC Motor Drives and DC Motor Drives Enters Period of Steady Growth

According to a recent IMS Research study, The Chinese Market for Low Voltage Motor Drives - 2012 Edition, revenue growth in this market slowed considerably in 2011 from an abnormally high 2010. Revenues from motor drives (excluding software and services) are projected to grow at a compound annual growth rate (CAGR) of 13.7 percent from 2010 to 2015.

The total Chinese market for low-voltage AC & DC motor drives (including software and services) was estimated at $2.68 billion in 2010. The Chinese Government’s RMB 4000 billion stimulation policy and other domestic consumption policies enabled healthy growth in the market to continue from 2009 to 2010.

“In the first half of 2011, the markets for low voltage motor drives were still growing strongly. In the second half of 2011, as the Chinese Government tightened monetary policies and imposed strict lending conditions; this caused delays in numerous large projects, such as high-speed railways, city metros, highways, and factory renovation projects. These policies are also causing financial strain for both end users and machine builders”, commented Wilmer Zhou, senior analyst and report author. In June 2011, the market went into a precipitous decline. The bad news first came from local small and medium machine builders in South and East China; many reported no new orders during the second half of the year and many small machine builders went bankrupt and closed. The low-voltage motor drive market has been more affected than that for the medium-voltage drives, because of its greater dependence on machine builders. Nevertheless, with $3.1 billion in revenues in 2011, China still accounted for 25 percent of the world market for low voltage motor drives.

The new report found that ABB and Siemens were the market leaders in the Chinese low voltage motor drive market in 2011, with 16 percent and 13 percent share respectively. Market leadership is concentrated, as the top five suppliers accounted for nearly 46 percent of the total. However, there is a large tail of suppliers, each with less than 1 percent of the total revenues. Wilmer states, “Because of the Japanese earthquake, component shortages, and other reasons such as the appreciation of the Japanese Yen in 2011, European and local Chinese suppliers are taking share from several Japanese suppliers.”

Growth in the Chinese market will continue, because of implementation of policies regarding motor  and motor driver efficiency and energy-saving renovations in various industries. But market growth will be at a lower rate than in the past few years as investment is reduced in the near future, with concerns over high inflation in China.
