Abstract

It was conducted a calculation of the parameters of the T-shaped equivalent circuit of a large asynchronous engine with the use of precise G-shaped equivalent circuit for nominal data and some characteristic sizes of the machines. It was chosen the calculation method of the control value of the multiplicity of a critical moment on the basis of a comparison of different options to determine this value was done. It was obtained a dependence of the multiplicity of the critical moment from the estimated value of the magnetizing current, taking into account the effect of displacement and saturation of leakage flux flow of stator and rotor windings due to the analytical interpretation of graphical method for finding the critical moment of the pie chart on the basis of experimental data of idle speed experiment and three experiments with short circuit.
