METHOD OF DIAGNOSTICS OF THE ELECTROMAGNETIC MECHANISM Russian patent published in 2018 - IPC G01M15/00 G01R19/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a measuring technique and can be used to diagnose electromagnetic mechanisms with a movable armature in which a permanent magnet is integrated in the magnetic circuit. Method for diagnosing the electromagnetic mechanism is that the diagnosed electromagnetic mechanism is irradiated with an alternating physical field, register with the help of the registration sensor a diagnostic parameter caused by the action of this field on the electromagnetic mechanism, and determine the technical state of the electromagnetic mechanism by comparing the value of the obtained diagnostic parameter with its reference value. In this case, the high-frequency electric field of the block of vibrator antennas is used as a variable physical field, by means of which a probing electromagnetic field is excited inside the electromagnetic mechanism, as a registration sensor, the winding of the electromagnetic mechanism is used, and as the diagnostic parameter, the total electromotive force, induced in the registration sensor by the probing electromagnetic field, is used. Sounding electromagnetic field is excited at a frequency equal to the resonant frequency of the circuit formed by the concentrated inductance of the electromagnetic mechanism and the constructive capacitance of the vibrator antennas.

EFFECT: technical result is the expansion of operational capabilities and the improvement of the quality of the functioning of the electromagnetic mechanism by ensuring the control of its current state.
