效率的不断提升、成本的进一步降低,将会成为中国高效电机生产发展的方向。国际标准按照电机能效将电机划分为三大类,分别是IE1(标准效能)、IE2(高效能)和IE3(优质高效),而永磁电机在国际最高水准IE3的能效标准上又进了一步。永磁电机是利用永磁体提供磁场的电动机,采用永磁体生成电机的磁 The continuous improvement of efficiency and further reduction of costs will be the direction for the development of efficient motor production in China. International standards According to the motor energy efficiency will be divided into three major categories of motors are IE1 (standard efficiency), IE2 (high efficiency) and IE3 (high quality and efficiency), while the permanent magnet motor in the highest international standards IE3 energy efficiency standards for a step . Permanent magnet motor is the use of permanent magnets to provide a magnetic field of the motor, the use of permanent magnet motor to generate the magnet
