METHOD FOR DETERMINING DYNAMIC CONDITION OF TRACTION ENGINE WITH SUPPORT AND AXIAL SUSPENSION Russian patent published in 2019 - IPC G01M17/08 

FIELD: machine building.

SUBSTANCE: invention relates to methods for monitoring the dynamic state of collector electric machines. In the proposed method of controlling the dynamic state of collector electric machines, vibration sensors are installed on the traction electric motor and data on its movement is recorded in three coordinates when rolling stock moves. Data on the movement of the engine is transmitted to the information processing unit, compared with the standard values and evaluate the current dynamic state of the traction motor. Vibration sensors are performed optical. Sensors contain a directional light source and a photocell, between which the core is located. Core is pressed against the contact surface by an elastic element. When a vibratory ejection occurs, the nucleus detaches from the contact surface, the light flux from the light source reaches the photocell.

EFFECT: increase in the accuracy of measuring mechanical effects on the traction motor.
