Content introduction: What has made Shenzhen, once once at the forefront of the times, once again picking up the wind, what makes the world's attention focused on this piece of land, what makes China's motor industry can be proud of the global, elated, all this Start with a small motor.
In the bright and spacious exhibition hall of Antoshan High-tech Industrial Park in Bao'an District, Shenzhen, a row of different types of motor products came into view. However, people are surprised to find that the motor shown here seems to be much smaller than a conventional motor. This Taiwan "trumpet" motor has a "strong" core, they are the core product of Antoshan Special Electromechanical Co., Ltd. - rare earth permanent magnet ironless motor.
"The sparrow is small and fully-equipped," not to mention the rare-earth permanent-magnet coreless motor is much smaller in size, but it has a lot of excitement, so that those motors "big brother, old" are shocked. “Traditional electric motors generally use silicon steel sheet and winding stator structure. The iron core is thick and easy to generate heat, and it loses much power in vain. The new motor uses rare earth permanent magnet motor technology to remove the iron core from the motor and eliminate the iron loss of energy. , is a revolutionary breakthrough in small and medium-sized motors." Chairman of the company Liang Xiwu introduced his products at the same time the face can not help but emerge proud expression.
In September 2009, a number of academicians of the Chinese Academy of Engineering and experts in the field of electromechanical technology were organized by relevant state agencies to gather in Shenzhen to conduct a rigorous inspection of the rare earth permanent magnet ironless core motor of Antoshan Specialty Electromechanical Co., Ltd. The results of the inspection made the experts on the scene full of praise.
Through a layer of checks, strict testing, a technical parameter and experimental data obtained, the use of iron proved that the new motor Antoshan company independently developed to achieve a major breakthrough in China's energy efficient motor, filling the domestic gap. Experts have demonstrated that compared with traditional motors, rare earth permanent magnet motors have achieved three breakthroughs in technology: First, compared with the traditional radial magnetic field structure design, axial magnetic field structure design is adopted, and power density and rotation are greatly improved. Moment volume ratio. The second is the use of a new winding process, high-pressure precision die-casting molding process and high-molecular composite packaging materials, effectively reducing the winding copper loss, improve motor reliability. The third is not to use silicon steel sheet as the stator and rotor core material, eliminating the magnetic damping and iron loss, reducing the driving power and reducing the iron loss heat source. Through these technological breakthroughs, the new motor has four major advantages in terms of performance: "high-efficiency and energy-saving", "light and material", "adjustable speed", and "strong reliability."
Compared with traditional motors, the stator of the new motor is iron-free, so it is small in size and weighs less than 1/2 of that of conventional motors. It can save 100% of silicon steel, 80% of steel, and 50% of copper. In addition, the new motor has no excitation, no brush, and no core, improves insulation performance, waterproof, moisture-proof, dust-proof, reliable operation, low temperature rise, and improves the environmental adaptability under extreme conditions. Tests on industrial sawing machines show that compared with the traditional motor drive system (induction motor with gear transmission), the system can save 30% power under the same working conditions. The actual application of the user proves that the 1.5-kilowatt and 3-kilowatt diesel power station adopting this technology can save about 40% compared with the traditional generator.
In the exhibition hall of Shenzhen Antuoshan Special Electrical Co., Ltd., we were also surprised to find 4 different types of exercise bikes. Different from Other fitness equipments, this type of exercise bike can convert kinetic energy into electric energy and store it through batteries to provide electric energy for small household appliances while people exercise and exercise. "A total of 1 hour of exercise, the savings of electricity is enough for a home bulb to light up for 10 hours." The company's product introducer introduced. In addition to fitness power generation, the motor can also be applied to other areas of family life, such as refrigerators, air conditioners and so on. Another outstanding feature of the new type of motor is energy saving, so it can also be called an active-saving motor: how much electricity it uses, how much power this motor automatically extracts from the grid, thereby reducing unnecessary losses.
According to preliminary calculations, if China replaces 1/3 of new electric motors, it can save nearly 50 billion kilowatt-hours of electricity each year, saving 500,000 tons of silicon steel sheets and 20,000 tons of copper, and can create an output value of nearly 10 billion yuan; if A total replacement of the electric motors that account for 65% of China's electricity consumption will save 10 years of power generation in the Three Gorges Power Station. If we increase the domestic market share of 10 major high-efficiency energy-saving products such as motors, air conditioners, and refrigerators, to 30% , It can realize annual electricity saving of about 75 billion kwh, emission reduction of about 300,000 tons of sulfur dioxide, and emission reduction of about 70 million tons of carbon dioxide. The economic and social benefits are considerable, which is of great significance to China's energy conservation and emission reduction.
The new rare earth permanent magnet ironless core motors have a wide range of applications, such as general-purpose equipment such as fans, pumps, and compressors. They can also be used in high-speed electric spindles, electric vehicles, numerical control machine tools, oil field pumping units, mobile power stations, and wind power generation. With unique advantages, the development prospect is broad.
Today, Antoshan Special Electromechanical Co., Ltd. has built 560,000 square meters of factory buildings, invested more than 300 million yuan to build 3 coreless motor automation production lines and more than 20 diesel power station production lines, 4 independent innovative new frequency conversion motor Speed ​​control system production line, four high-speed patch electronic production lines, two wave soldering production lines, a mold processing production line and various types of CNC machining equipment more than 300 sets. After entering the “Twelfth Five-Year Plan†period, the company once again made a major development plan. It is expected that 40 automatic production lines will be built in 3 to 5 years to achieve a leap-forward development in motor production scale.
As the core component of various electrical and mechanical devices, the motor, like the heart of human beings, provides a constant source of power for machines. The new type of rare earth permanent magnet coreless motor has injected fresh blood into the motor field in China, which has made it a good start for China's “Twelfth Five-Year†energy-saving and consumption-reduction task.
