  • Method of determining the efficiency of asynchronous motors and apparatus for carrying out the method
    Patent number: 5659232
    Abstract: In the no-load state of operation of a running asynchronous motor, after separating the no-load copper losses as well as the sum of the iron losses and friction losses and taking into consideration the rated current of the motor and the rated rate of rotation, an upper limiting value of the rated efficiency of the motor is determined while assigning the iron losses and the friction losses to the stator losses and a lower limiting value of the rated efficiency of the motor is determined while assigning the iron losses and the friction losses to the rotor losses.
