ABSTRACT
Substantiation of the value of the signal sampling frequency in experimental data reading in the problem of parameters identification of induction motor equivalent circuit. Methods for describing electromagnetic processes known from the theory of electrical machines and a method for solving differential equations are used. The solutions obtained make it possible to determine the value of sampling frequency in experimental data reading while using the corrective factor which depends on the power of the motor. The results presented in the paper allow specialists to make a reasonable choice of sampling frequency for experiments with DC power supply of the stator. Using of the proposed corrective factor will better the results of parameters identification. Proposed recommendations can be used for the development of algorithms and software for microprocessor systems of AC drives with induction motors for the identification of equivalent circuit parameters.
