FIELD: engines and pumps.
SUBSTANCE: disc with reference moment of inertia is installed on flange of output shaft, and moment of inertia of electric motor is determined as ratio of the product of angular acceleration of system of rotating masses of system "disc with reference moment of inertia, electric motor" times moment of inertia of disc with reference moment of inertia to difference of angular acceleration of system of rotating masses "electric motor" and angular acceleration of system of rotating masses "disc with reference moment of inertia, electric motor".
EFFECT: possibility of determining moment of inertia of electric motor without conducting brake tests.
