Recently, the mining explosion-proof permanent magnet synchronous variable frequency motor independently developed by Shandong Ouruian Electric Co., Ltd. in Tai'an High tech Zone has been successfully selected for the "2024 Shandong Province Industrial Advanced Applicable Green Low carbon Technology Equipment List". It is the only one in the category of high-efficiency energy-saving equipment in our city. What is its "green magic"?
Traditional mining equipment often "steals" a large amount of electricity due to low motor efficiency and multiple transmission links, resulting in a waste of resources. Permanent magnet motors benefit from the permanent magnetic field generated by permanent magnets. There is no need for additional work induction to establish the rotor magnetic field. The efficiency can generally reach 90%-95%, and it can achieve direct drive loads and variable frequency starting. "Compared with the traditional drive mode, the permanent magnet motor drive system is simpler, more efficient, and has lower power consumption. If a 560-kilowatt permanent magnet motor is used, it produces 330 days a year, 16 hours a day, and is calculated at 0.7 yuan per kilowatt-hour, it can save about 549,974 kilowatt-hours of electricity each year, saving 385,000 yuan in electricity bills," said Du Shun, general manager of Shandong Ouruian Electric Co., Ltd. "This is equivalent to saving 68 tons of standard coal and 0.5 tons of carbon dioxide annually."
"At present, the permanent magnet motor has been put into use in well-known domestic enterprises such as National Energy, Shandong Energy, Jinneng Holdings Group, and Ningde Times. Among them, the permanent magnet motor applied in July 2019 in the national green mine - Wuxue Changjiang Mining Co., Ltd. can save about 1.4 million kWh of electricity and nearly 1 million yuan in annual electricity bills for Changjiang Mining, promoting the path of green mining for enterprises." said Du Shun.
Shandong Ouruian Electric Co., Ltd. is a national high-tech enterprise, a national specialized and innovative "little giant" enterprise, and a national intellectual property advantage enterprise specializing in the research and development and manufacturing of low-speed high-power permanent magnet motors, frequency converters, electrical control systems and other equipment in China. The enterprise has three provincial-level R&D platforms and a national level talent team. The intelligent permanent magnet direct drive motor system developed by the enterprise is green, energy-saving, intelligent and efficient, achieving direct drive load and improving transmission efficiency by more than 15%. It has won more than 10 scientific and technological awards such as the second prize of National Science and Technology Progress Award, drafted 10 national industry standards, and was selected for the "National Energy saving Technology Equipment in the Industrial and Information Technology Field", "National First (Set) Major Technology Equipment", "Science and Technology Innovation China" leading technology list, serving key projects at home and abroad. Among them, the "Plateau type" permanent magnet motor, which has been applied for 24 years, was selected for the "Guinness World Record".
In recent years, our city has attached great importance to green, low-carbon and high-quality development, continuously promoted green and low-carbon technology and equipment, continuously promoted the deep integration of digitalization and greening, and achieved cost reduction, quality improvement and efficiency enhancement. The innovation of Shandong Ouruian is a microcosm of our city's green transformation. With the accelerated promotion of such technologies, citizens will witness more symphonies of "mine green" and "sky blue".
