With China's accession to WTO, the domestic motor industry faced enormous competitive pressures and challenges. Seeing from the international and domestic development trend, developing China's high-efficiency motors is necessary and it is also a market requirement. So that make our electric motor products keep up with the international trend,. According to statistics, in 2002 China accounted for more than 60% on the electrical motor power consumption of the country. And the power is about 35%, which is power-hungry.

three asynchronous motor

It is reported that China's industrial energy consumption accounts for 70% of total energy consumption, including electrical energy consumption accounts for 60% to 70% of industrial energy consumption, coupled with the non-energy industrial motors, motor actual energy of the total energy consumption more than 50%. Now low proportion of applications of energy efficient motors. According to the National Quality Supervision and Inspection Center of small motors for domestic motor 198 key enterprises sample survey, the proportion of energy efficient motors which reach more than 2 only 8%, which on the whole society had a tremendous waste of resources. Why efficient motor has not really enter the market? The higher prices, the market situation is not ideal, so that fewer manufacturers, resulting in user awareness of efficient motor is not enough, this is one of the main reasons. This year, the Ministry of Industry on March 26 issued the "2013 industrial energy efficiency and green development special action plan" put forward the notification, in 2013 will focus on promoting the implementation of special programs to enhance the energy efficiency of the motor. Target special action is: to achieve savings of 1% of the country's industrial electricity consumption (about 300 million degrees), to explore the pattern of industrial energy efficiency and green development and implementation of ways to achieve a point, and drive energy conservation and comprehensive utilization of overall industrial progress. According to an embodiment, in 2013 the Ministry will promote efficient motors, eliminating six aspects of the existing inefficient motors and motor systems and other aspects of energy-saving technological transformation, extension, elimination and energy-saving motors and motor systems 100 million kilowatts, expand market share high efficiency motor and promote the upgrading of electrical products and industrial upgrading. Thus, the government is to promote efficient motor, but needs to continue to increase promotional efforts. But in the current market economy, short-sighted companies are reducing their procurement costs, which is a high efficiency motor price become a contradiction. Therefore, the promotion of efficient motors also need politicians to improve the focus on efficiency, high efficiency motor conduction efficiency can quickly link to the downstream market in order to present the hugely popular scene.

Recently, India launched anti-dumping investigations to China cold rolling and hot rolled stainless steel products. and even levied anti-dumping duties, it will increase China's stainless steel products export pressure, influencing on the export of stainless steel.
India commerce ministry had made a statement that will make final anti-dumping on the imported 304 series hot rolled stainless steel, suggesting to levy anti-dumping duties on 304 series of hot rolled stainless steel come from China, South Korea and Malaysia
A Shanghai analysts said that this statement will increase China's stainless steel products export pressure, in 2015 China's steel export situation which is not optimistic, export of stainless steel products will also be suppressed.
In addition to hot rolled stainless steel products, the same to cold rolled stainless steels. In early the end of 2014, Indonesia's anti-dumping committee made announcement that according to the domestic industry application, decided to levy anti-dumping investigation for cold-rolled stainless steel from China, Thailand, Malaysia, South Korea, Singapore and Taiwan.

First, the selection of the planetary gear ratio selection:

When choosing a planetary gears, we must first get reduction ratio. determined after reduction ratio, add your choice of servo motor rated torque multiplied by the reduction ratio, the value obtained is less than the principle product samples provided similar gear rated output torque , but also consider the maximum operating torque of the motor overload and actual required driving. It is less than the required maximum operating torque of 2 times nominal output torque.

Second, get the size specifications planetary gear:

Please select the smallest gearbox after the above conditions which meets, small size and relatively low cost reducer. If you have enough space motor reducer straight line connection, you can also select a corner reducer, it can turn 90 degrees to the torque.

Third, the precision planetary gear (backlash) selection:

As talked on yesterday, we are here now to introduce the fours types of Gear redactor in power transmission industry.

Cycloid gear reducer, using cycloid tooth meshing is an advanced design, new style structure of the reduction way, which can be both clockwise and reverse operation. The biggest feature is that it has the high transmission efficiency and also a wide ratio transmission range. And power is available from 10KW to 50000kW. Otherwise, its size and weight is much smaller than helical gear reducer and worm reducer. However, its structure is more complex high precision. It is widely used in petrochemical deceleration devices, light industry, pharmaceutical industry, textile, metallurgy, mining, sewage treatment and construction machinery and other transmission machinery.

Belt reductor, speed redactor with belt, it is high efficiency, long life, compact structure, smooth transmission, easy removal and other features that allow positive and negative direction of running, in large fermentation devices more often.

Worm gears, worm gearbox with worm gear drive is mainly used for large occasions, with smooth contours and other transmission compact size advantages of small work, but less efficient single-stage worm reducer thus used more two-Worm reducer is seldom used. Range of single-stage worm gear transmission ratio is generally 10-70.

Gear reducer, it mainly gets cylindrical gear reducer and bevel gear reducer. cylindrical gear reducer which is the most widely using. which can deliver the power range from small to 4000kW peripheral speed is also available from low 60-70m/s; and the input shaft and output shaft position bevel gear reducer to 90o configuration making it suitable for input and output shaft perpendicular to each other occasions. The main features of the gear reducer is durable and easy to maintain high efficiency, according to the reduction gear stages can be divided into single-stage, two, three or even multi-level, avoiding gear outside dimensions too large, generally when the ratio of 8 The following can be used when a single-stage gear reducer, the best selection of two or more stages and it is greater than 8.
