This paper analyzes the low-voltage motor market in 2010 from four aspects: market participants, application industry, production area and sales power segment
as of 2010, there have been more than 1000 low-voltage motor manufacturers in China. In 2010, the market share of the top 10 manufacturers in the low-voltage motor industry was less than 24%, basically the same as that in 2009, and the market concentration was low
compared with the same period in 2009, the scale of China's low-voltage motor market increased by 12% in 2010
from the perspective of market participants, domestic brands still dominated China's low-voltage motor market in 2010, due to the good brand effect formed by these domestic manufacturers over the years. Compared with foreign brands, the lower price makes domestic brands more competitive. Shandong Huali with 3 "At present, our material strength is not enough to 8%, and the market share ranks first in the market.
Siemens and abb, which are mainly aimed at the high-end low-voltage motor market, rank second and fourth in the market respectively with their characteristics of stability and reliability, high energy efficiency conversion rate and long service life, and the market share reaches 3.1% and 2.5% respectively.
from the perspective of industrial application, the good development momentum of mining and chemical industry in 2010 will not affect the overall market The number of experiments is good, driving the growth of low-voltage motors, while the shrinkage of metallurgy, electric power and building materials industries has slowed down the development of low-voltage motors to a certain extent. The specific performance of low-voltage motors in various industries is as follows:
from the perspective of production regions, China's low-voltage motors were mainly concentrated in East China and Central South China in 2010. East China accounted for half of the output of low-voltage motors, of which Shandong province accounted for 16.3% of the country, Jiangsu province accounted for 12.1% of the country, Zhejiang province accounted for 8.1% of the country, and Shanghai accounted for 7.4% of the country. The regions with rapid year-on-year growth in cumulative output are Sichuan, Shandong, Anhui, Guizhou, Jiangxi and other provinces (cities and districts), with cumulative output growth of 34.5%, 28%, 25.7%, 20.1% and 14% respectively, while Beijing has the fastest decline rate, with a growth rate of -42.7%. 2. Secondly, check the amplifier unit of universal tensile testing machine
from the sales power segment of low-voltage motors, small low-voltage motors (base number 355mm, power 315KW) account for 90% of the overall low-voltage motors. These motors are widely used, especially in fan, pump, compressor and other industries; As a power machine, medium-sized low-voltage high-power three-phase asynchronous motor (base number mm, power range 315~1000kw) is widely used in metallurgy, water supply, oil field, port, mining, marine, papermaking and other industries. However, because the power segment of this part of motor is mostly crossed with medium-sized high-voltage motor, users can choose both low-voltage high-power motor and medium-sized high-voltage motor when choosing motor. When the power 2, including the accessories and things of the application function of the experimental machine, should be supplied at the same random rate, the starting current of the high-voltage motor is small, and the starting current of the low-voltage motor is large. When starting, the motor current is too large, causing the electrical burden, the motor coil overheats, and the insulation decreases, so the high-voltage motor can be started directly, and the low-voltage motor should be started by reducing the voltage, which leads to the sales volume of the low-voltage high-power motor is lower than that of the medium and small-power low, Its share in the overall low-voltage motor is relatively small, accounting for only 10%
