Аннотация

The analysis results of the dynamic stability of the electric drive in oscillatory mode by means of the supply voltage phase modulation have been provided. The determining procedure of oscillatory electromagnetic torque and its starting and damping components, as well as of motion law for the motor operating element subject to inertial, damping and positional load has been developed and tested. It was shown that the valve electric drive dynamic stability in oscillatory mode can be estimated from the time behaviour of the torque angle under the dynamic transition to the static stable mode. The natural frequency-regulating algorithm of the electric drive has been determined, operating by regulating one of the phase-to-earth voltages, as well as a pull-in criterion operating under the variation of load parameters by the start of the electric drive on the specified oscillatory frequency. A chain diagram of electric drive in oscillatory mode with variable rest frequency has been contributed. The obtained research results can be recommended for use in engineering of low-frequency electromechanical oscillatory complexes in control and vibration test systems.
