HALL SENSOR DIAGNOSTIC SYSTEM AND METHOD FOR ITS APPLICATION Russian patent published in 2021 - IPC G01R29/00 

FIELD: diagnostic equipment.

SUBSTANCE: invention relates to systems for measuring alternating magnetic quantities, in particular to systems and methods for diagnosing Hall sensors. The expected result is achieved by the fact that a Hall sensor diagnostic system containing a frequency converter, the first output of which is connected to an electric motor, and the second one to the first measuring input of the signal diagnostics and analysis unit, is characterized by the fact that a cogged pinion is mounted on the rotor shaft of the electric motor, made with the possibility of contactless interaction with three Hall sensors mounted on the motor housing, while the Hall sensors through current converters that convert input pulse signals into normalized DC output signals are connected to the second, third and fourth measuring inputs of the signal diagnostics and analysis unit, the information output of which is connected to the automated workplace of the operator of the Hall sensor diagnostics system.

EFFECT: increase in Hall sensors’ diagnostics accuracy, increased manufacturability of the diagnostic device.
