Analysis of the behavior of asynchronous electric drive with a closed scalar control system when changing the inductance of the magnetizing circuit

The article was devoted to the study of an automated electric drive with a scalar closed-loop speed control system. Severe duty and operating modes determine actual service life. Wear induction motor, as key link drive, associated deviation from nominal parameters. parameters motor equivalent circuit determined resultant change characteristics. accuracy adjustment regulators optimal algorithms in system drive. In continuous operation possibility auto-tuning regulators, which requires stopping or no-load mode, excluded. paper considered influence magnetization mutual inductance value on behavior Evaluation performed basic energy (power factor, efficiency factor) mechanical (speed, electromagnetic torque) characteristics
