High-efficiency three-phase asynchronous motor refers to a motor with higher efficiency. Generally, its efficiency value can reach the standard level two energy efficiency. And high-efficiency motor manufacturers remind that high-efficiency motors recycle new motor design, new technology and new materials, and reduce electromagnetic energy, The loss of heat and machine energy improves output efficiency.Compared with ordinary three-phase asynchronous motors, its efficiency is increased by 4%-8% on average.

　　从节省能源、掩护情况出发，高效率三相异步电动机是现今电机行业成长的趋势，我国最新出台的IEC60034-30尺度将电机效率分为IE1(老式Y系列电机)、IE2(YE2高效率电机)、IE3(YE3超高效率电动机)、IE4(一级能效电动机)四个品级。今朝遍及应用于机器设备行业中的三相异步电动机多为二级能效高效电机和三级能效超高效率电机。

　　So how do high-efficiency motor manufacturers improve the efficiency of three-phase asynchronous motors?

　　The methods for high-efficiency motor manufacturers to improve the efficiency of motors are mainly from the design and manufacture of high-efficiency motors, to the selection, operation, adjustment, and inspection of motors. The results of energy-saving methods should be considered from the entire utilization cycle of the motor. High-efficiency motor manufacturers consider the following aspects to improve the efficiency of the motor from these aspects.

　　The design of high-efficiency and energy-saving motors refers to the use of modern design methods such as optimized design skills, new material skills, control skills, integration skills, and test and detection skills to reduce the power loss of the motor, improve the efficiency of the motor, and design an efficient motor.

　　When the motor converts electrical energy into machine energy, it also loses a part of energy. The typical exchange motor loss can generally be divided into three parts: solid loss, variable loss and stray loss.Variable loss changes with load, including stator resistance loss (copper loss), rotor resistance loss and brush resistance loss; robust loss has nothing to do with load, including core loss and machine loss.The iron loss is composed of hysteresis loss and eddy current loss, which is proportional to the square of the voltage, and the hysteresis loss is also inversely proportional to the frequency; other stray losses are machine losses and other losses, including bearing friction losses and electric fans, Windage loss caused by the rotation of the rotor, etc.
