目前,我国全社会发电量的70%的能耗在工业,工业中能耗的70%在电机,因此,破解电机系统节能是工业发展过程中减少能源成本的重中之重,亦是深化节能降耗推进产业结构调整的关键一环。在此背景下,电机节能对社会节能意义重大。国家电机能效提升办公室做过统计,工业领域电机能耗每提高1%,可年节约用电量260亿千瓦时左右。通过推广高效电机、淘汰在用低效电机,对低效 At present, 70% of the total power generation in our country consumes 70% of the energy in the industrial and industrial sectors. Therefore, to solve the energy-saving problem of the motor system is the most important energy cost reduction in the industrial development and also to deepen the energy saving Reduce consumption and promote the adjustment of industrial structure. In this context, motor energy saving is of great significance to society. National Electrical Energy Efficiency Office did statistics, the electrical energy industry for every increase of 1%, the annual electricity consumption of 26 billion kilowatt hours or so. By promoting efficient motor, out of use of inefficient motor, inefficient
