INVESTIGATION OF ASYNCHRONOUS MOTORS WITH NONLINEAR ELEMENT IN THE CHAIN SLIP-RING MOTORS

On the basis of experimental data, the study of electromagnetic induction resistivity parameters of the ferromagnetic elements of the mathematical model of induction motor with frequency converter circuit in the phase of the rotor. This model allowed to investigate the effect of the rotor current frequency on the magnitude of the nonlinear resistance, included in the rotor circuit. Rotor current frequency control allows to create the desired mechanical characteristics of the induction motor and creates real prerequisites for reducing the weight and size parameters of nonlinear resistors.
