FIELD: engine building.
SUBSTANCE: method for assessment of a vibration state of an electric engine is disclosed. The method includes stages of: determination of a value of vibrations of electric engine (1) by measurement of acceleration and/or speed of vibrations of electric engine (1), using sensor (5) of vibrations of electric engine (1), while vibrations are measured in at least one direction, and the value of vibrations is each of measured at least one direction, determination of current frequency (n) of rotation of the electric engine, comparison of the value of vibrations with a reference value of current frequency (n) of rotation of electric engine (1), comparison of the value of vibrations with the reference value of the current frequency of rotation, and determination of an assessment criterion for assessment of the vibration state of the electric engine based on comparison of the value of vibrations with the reference value. Corresponding electric engine (1), as well as a system consisting of electric engine (1) and testing system (2), using which the vibration state of electric engine (1) can be calibrated, and reference values can be created, are also disclosed.
EFFECT: improvement and increase in the accuracy of a method and a system for assessment of a vibration state of an electric engine, as well as an electric engine and a fan, in such a way that a reliable conclusion on the vibration state of the electric engine can be made.
