Vigorously promote application of high efficiency and energy saving motor electrical engineer

In order to improve the energy efficiency, energy conservation and emissions reduction goals, general electrical engineer is an important way promoting application in high efficiency and energy saving motor, this method is especially applicable to the need to run a long time and high load situations, such as steel, oil field, textile, chemical industry, etc., these motor used in the industry are often need to run 24 hours a day uninterrupted, if use the high efficiency and energy saving motor, energy-saving effect is very significant. This not only can save power to reduce production cost, has the good economic efficiency, at the same time also can reduce www.facebook.com/dongfeng.motor carbon emissions, produce good social benefits. Therefore, in terms of energy conservation and environmental protection, high efficiency, the development of highly efficient motor work is an urgent task. In the course of the development of efficient and highly efficient motor, an important task is to take to be able to gauge the wastage of the nonlinear and complex structure and various influencing factors of calculation method, the different structural parameters of stator rotor, material properties, and other motor part factors affecting the specific impact of motor loss, and various losses in the motor on the basis of system analysis, to improve the structure of the motor design, finally it is concluded that the best design plan, achieve the goal of consumption. , therefore, a detailed analysis on characteristics of the motor loss is the first task of super-efficient asynchronous motor research work, in order to achieve this goal, based on modern computer technology is a new loss calculation method for motor loss system analysis, from the microscopic view on how to develop the energy saving scheme has theoretical guidance meaning. In addition, in the process of asynchronous motor the development of highly efficient motor, accurate testing of the motor loss is also very important. For a long time, the motor structure and influence factors of additional loss is relatively complex, test is relatively difficult, previous treatment is using 0.5% of the input power to replace, and the proportion in the actual test does not reflect its true value loss, this will lead to some is not actually achieve efficient motor was judged to be efficient, make the motor efficiency defined error is produced. In IEC latest standards, clear recommendations according to the 112 b method to measure the additional loss, and the whole test process, accurate test and separation of the motor racing iron loss is a key link, but because of the influence factors of no-load iron loss is various, therefore, how to realize the accurate asynchronous motor racing iron loss test, test of super efficient motor loss and efficiency determine is of great significance.
