APPARATUS FOR OPERATIONAL MONITORING OF HEATING OF ELECTRIC ENGINES Russian patent published in 2022 - IPC H02K15/12 H04W24/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular, to monitoring the thermal state of electric engine windings. The technical result is achieved by the apparatus for operational monitoring of heating of electric engines containing a heating temperature sensor for the electric engine windings, a hollow metal bolt, a power source, wherein the hollow metal bolt is screwed into the process hole in the body of the electric engine until contact with the core, located in the terminal box, installed inside the lower part of the hollow metal bolt is a heating temperature sensor for the windings of the electric engine connected with the control unit connected with the output of the power source provided with a charge accumulator, and the input of the power source is connected to the terminals of the three-phase winding of the electric engine, located in the terminal box, the output of the control unit is connected with a Wi-Fi communication module, by means of Wi-Fi wireless technology transmitting signals to the transceiver Wi-Fi unit exchanging information with the signal receiver.

EFFECT: increase in the accuracy of measuring the temperature of the electric engine winding, versatility of use of the apparatus for various standard sizes of electric engines, and remote transmission of information on the temperature state of the electric engine stator windings.
