Summary:The basic technical parameters of a series of energy-efficient asynchronous motors are presented. The primary competitive advantages of the 7AVE series are indicated. The main modifications and specialized variants produced based on it are listed. It is noted that modern designs are more efficient (in comparable energy efficiency classes) than the previously produced AIR and 5A series. The definition of the term “service factor” is clarified. The problems of choosing the rational outer diameter of stator cores are discussed. The advantages of CENELEC matching for implementing the highest classes of energy efficiency of low- and medium-power asynchronous motors are noted. The issue of the potential to design asynchronous motors of an ultrahigh energy efficiency class (IE4) is touched upon. The calculated parameters of a motor type with the IE4 efficiency class are presented.
