ELECTRIC ENGINE AND METHOD FOR EVALUATING THE VIBRATION STATE OF AN ELECTRIC ENGINE Russian patent published in 2022 - IPC H02K11/33 H02K11/20 

FIELD: electrical engineering.

SUBSTANCE: proposed is an electric engine with a stator (2), a rotor configured to rotate relative to the stator, and engine electronics. The engine electronics are located in the electronics body (7) and mounted on a printed circuit board (10). At least one vibration sensor (13) is located on the printed circuit board (10), configured to measure the acceleration and/or speed of vibration of the electric engine (1) in at least one direction. The printed circuit board (10) is also connected vibrationally and technically with other components of the electric engine (1) by means of at least one connecting element, so that at least part of the vibration of the electric engine is transmitted to the vibration sensor (13).

EFFECT: increase in the reliability of determining the vibration state of an electric engine.
