New energy-saving motors lead the manufacturing industry into the fast lane
With the active promotion of national energy conservation and emission reduction, as well as the gradual implementation of subsidy policies for high-efficiency and energy-saving motors, high-efficiency and energy-saving motors are experiencing explosive growth. The country has also introduced a series of preferential policies for high-efficiency motors, bringing good development opportunities and broad market prospects to related enterprises. Many companies are actively adjusting their business structure to welcome the golden period of the energy-saving motor equipment market.
Tianjin Linyuan Machinery Equipment Co., Ltd. was founded in 2016 and is located in Wuqing National Development Zone, Tianjin. It is a high-tech enterprise that integrates the research and development, production, and sales of high-efficiency rare earth permanent magnet synchronous motors. The registered capital of the company is 20 million yuan, covering an area of 3000 square meters, and the total assets are 400 million yuan. The company has advanced standardized permanent magnet motor production workshops, sophisticated production equipment, advanced production and manufacturing processes, complete testing methods, and strong technical strength. It has taken the lead in passing the ISO9001-2015 quality management system certification.
Tianjin Wuqing District is located at the center of the two municipalities directly under the central government of Beijing and Tianjin, known as the "Beijing Tianjin Corridor" and "Beijing Tianjin Pearl". It is the intersection of the three provinces and cities of Beijing Tianjin Hebei, and an important core area and bridgehead for the coordinated development of the country's Beijing Tianjin Hebei region. Wuqing Development Zone is a national level economic and technological development zone and a national level high-tech industrial park established with the approval of the State Council. After more than 20 years of development, Wuqing Development Zone has formed an industrial cluster dominated by six major industries: electronic information, new materials, new energy, machinery manufacturing, automobiles and parts, and biomedicine.
Since its establishment, Tianjin Linyuan Machinery Equipment Co., Ltd. has been committed to the research and experimentation of efficient rare earth permanent magnet synchronous motors, and has a top domestic research and design team in the field of rare earth permanent magnet motors. Over the years, the company has continuously improved its design and production processes through scientific research and practice under various complex and diverse working conditions and load characteristics. Currently, it has successfully developed various models of rare earth permanent magnet motors with high and low voltage power coverage ranging from 22KW to 2500KW. Compared with ordinary induction motors under the same load and working conditions, the energy-saving rate is as high as 15% to 40%, ranking first among other types of energy-saving motors in the country. The high-efficiency rare earth permanent magnet synchronous motor series of Linyuan Machinery has been recognized by the National Development and Reform Commission as a national high-tech industrialization demonstration project.
At present, the high-efficiency rare earth permanent magnet synchronous motor produced by Tianjin Linyuan Machinery Equipment Co., Ltd. has seven unique advantages. One is a significant improvement in energy efficiency. Due to the implementation of rare earth elements in the rotor, there is less loss, and the energy efficiency exceeds the highest energy efficiency level 1 of the national standard "GB18613-2012 Energy Efficiency Limit Values and Energy Efficiency Grades for Small and Medium Three phase Asynchronous Motors". The second is the efficiency of the motor at low load rates. At a load rate of 60%, the efficiency can still be guaranteed at 94%, while asynchronous motors are at 80% or even below. Thirdly, the motor speed can be adjusted arbitrarily according to the production situation while maintaining high efficiency. The fourth is to use variable frequency starting to avoid impact on equipment and the power grid. The power factor is almost 1 (even capacitive), so the factory power grid can reduce capacitor reactive power compensation. Six is low temperature rise. Through actual testing, under the same conditions, the working temperature of rare earth permanent magnet motors is 15 ℃ -20 ℃ lower than that of asynchronous motors. Seven is a decrease in current. Efficient rare earth permanent magnet synchronous motors do not require reactive excitation current, resulting in a significant reduction in stator current. At present, the company has obtained utility model and invention patent authorizations for two technologies, and is applying for patents for 12 technologies.
According to statistical calculations, the current number of electric motors in China is 1.7 billion kilowatts, with a total electricity consumption of about 3 trillion kilowatt hours, accounting for 64% of the total electricity consumption in society. Among them, the total electricity consumption of electric motors in the industrial sector is 2.6 trillion kilowatt hours, accounting for about 75% of industrial electricity consumption. Every one percentage point increase in the energy efficiency of industrial motors can save about 26 billion kilowatt hours of electricity annually. Promoting efficient and energy-saving motors has huge economic benefits and a very broad market prospect.
In recent years, relevant national departments have also frequently taken measures to actively promote efficient motors and forcibly eliminate inefficient motors. In 2012, the National Standardization Administration issued the mandatory standard "GB18613-2012 Energy Efficiency Limits and Grades for Small and Medium Three phase Asynchronous Motors", and began implementing the mandatory minimum energy efficiency standard. In 2013, the Ministry of Industry and Information Technology issued the "Electric Motor Energy Efficiency Improvement Plan (2013-2015)", requiring enterprises to phase out 50% of low efficiency three-phase asynchronous motors by the end of 2015. In May 2014, the General Office of the State Council issued the "2014-2015 Action Plan for Energy Conservation, Emission Reduction and Low Carbon Development", which decided to comprehensively promote rare earth permanent magnet motor technology; And in June of the same year, the "Catalogue for the Elimination of High Energy Consuming and Backward Electromechanical Equipment (Third Batch)" was released, in which 95% of the eliminated items were inefficient three-phase asynchronous motors.
According to the relevant person in charge of the company, high-efficiency rare earth permanent magnet synchronous motors can be widely used in various industrial fields such as petrochemicals, power generation, mining, metallurgy, cement, medicine, papermaking, rubber, plastic wire drawing, as well as civil fields such as urban water supply, heating, sewage treatment, cold storage, central air conditioning, etc., with broad market prospects. Taking the steel industry as an example, according to statistics, a steel enterprise with an annual production capacity of 10 million tons of steel is equipped with inefficient motors ranging from 350000 kW to 550000 kW, which consume billions of yuan in electricity bills annually. With the strong promotion and implementation of future national industrial policies and energy conservation and emission reduction policies, a huge number of low voltage and high voltage inefficient motors will be replaced by high-efficiency motors, bringing huge market space for the promotion and application of high-efficiency rare earth permanent magnet synchronous motors.
At present, Tianjin Linyuan Machinery Equipment Co., Ltd. has established energy-saving cooperation with Xuangang Company and Chenggang Company of Hebei Iron and Steel Group, and both parties have achieved significant benefits. At the same time, the company has also carried out a series of practical cooperation with Tianjin Changlu Haijing Group Co., Ltd. and 11 subsidiaries, Shandong Luzhou Biotechnology Co., Ltd., Shaanxi Dongling Group, Baotai Group and other related enterprises in the fields of non-ferrous metals, papermaking, cement building materials, petrochemicals, power generation, biology, building materials and other industries.
It is reported that in the next step, Tianjin Linyuan Machinery Equipment Co., Ltd. will comprehensively promote the application of various types of high-efficiency rare earth permanent magnet motors by establishing and improving sales channels, strengthening quality management, and perfecting process flow. In terms of process flow, the company will continuously adopt advanced process methods and equipment to achieve semi automated and automated production in offline and fixed rotor assembly. The assembly process and finished product process will use industrial robots and intelligent manufacturing technology to significantly improve production efficiency and increase output capacity. On the other hand, we will continue to increase research and development investment, actively develop 2-pole 3000r pm high-efficiency permanent magnet motors, and further expand their application scope. Simultaneously developing various permanent magnet motors with proprietary applications. At present, specialized permanent magnet motors such as high-efficiency permanent magnet elevator motors, high-efficiency large-scale steel rolling motors, and special automotive main drive permanent magnet motors have been included in the research and development plan. In addition, it is necessary to continuously improve product matching and conduct research and production of permanent magnet synchronous frequency converters in addition to developing motor series products.
It is worth mentioning that in November this year, Tianjin Linyuan Mechanical Equipment Co., Ltd. signed an agreement with PICC to insure a product liability insurance for efficient rare earth permanent magnet synchronous motors, and also bought a safety guarantee for customers.
