INSTALLATION FOR IDENTIFICATION OF DC MOTOR PARAMETERS Russian patent published in 2024 - IPC G01L5/24 H02K26/00 G01L25/00 G01R31/34 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to devices for determining parameters of electrical machines, and can be used in creating installations for identifying parameters, for example, DC torque motors. Apparatus for identifying parameters of a DC motor comprises motor 1 proper, the stator of which is fixed in the housing, and the rotor is kinematically connected by means of friction shaft 5 to the rotor of tacho generator 4, which is also fixed on the housing. Also contains adjustable power supply 14 connected to the rotor input of motor 1, meters of voltage and current of the motor, its rotation frequency and the angle of rotation of the reference load, which balances the load moment created relative to the rotational axis by friction module 6, to which reference weight 7 is rigidly connected by means of rod 13. Friction module 6 is a clamp with inner cylindrical surface enclosing friction shaft 5, compression force of which is adjusted by movement of screw 6.1. To carry out identification of engine parameters, the installation comprises microcontroller 20, to the first to fourth input ports of which the outputs of the first to fourth scale amplifiers 15-17, 19 are respectively connected, inputs of which are respectively connected to outputs of controlled power supply, DC motor, tachogenerator and phase-sensitive rectifier 18, to the input of which there connected is a measuring device of the deflection angle of the reference load, which is made in the form of an angle sensor, rotor 8 of which is fixed on the friction module, and stator 9 is fixed in the housing of the installation.

EFFECT: high accuracy of measuring parameters.
