FIELD: controlling.
SUBSTANCE: group of inventions relates to the field of diagnostics and control of electric engines. Group of inventions comprises a method for assessing the operational readiness of an electric engine, including the stages of: initiating the process of acceleration of the electric engine, wherein the speed of rotation during the acceleration process varies by several steps of the speed of rotation; generating at least one measured value by accordingly measuring a physical quantity using an electric engine sensor at no less than one of the steps of the speed of rotation; loading at least one parametric information from the electric engine parameter memory unit and estimating said at least one measured value for at least one of the steps of the speed of rotation applying said at least one loaded parametric information, as well as an electric engine with a parameter memory unit and with a parametrisation interface, as well as a fan with such an electric engine and with an impeller.
EFFECT: increase in the reliability of electric engines.
