Formation of Starting Torque of Double-Fed Induction Motor

Abstract

The article deals with studying the way of determining the supply voltage parameters for induction motor with frequency control in the rotor circle under the conditions of the hard start. The method of experiment planning results in the regression model of the frequency in the power net and the angle of mismatch of electromagnetic fields of the stator and the rotor of the double-fed induction machine that allows determining the values of signals to form the maximum admissible starting torque of the electric drive with the minimum torque power.
