This paper presents a developed method to calculate the parameters for thirty-three squirrel cage induction motors operating at three-phase ac voltage of 380 volts. These motors are the total product of an Egyptian factory holding a license from SIEMENS international company to fabricate all parts of these motors. The parameters of all mentioned motors are computed based on the proposed method. Then, the performance characteristics of these motors are investigated at full-load using the conventional equivalent circuit in order to validate the proposed method. The obtained curves achieve significant convergence with the full-load values provided by the data sheets of investigated motors. This confirms the validity of the proposed method.

Abstract Agriculture is a socially significant sector of the economy. The growth of agricultural production contributes to the stable development of society. It is necessary to use new mechanisms driven by induction motors to increase agricultural productivity. Three-phase induction motors are mainly used in the electric drive of agricultural machines. At the same time, it is advisable to use a single-phase network to supply power to remote farms. In this regard, the development of a single-phase electric drive using three-phase motors becomes relevant. In this work, a study of an original semiconductor device for starting a three-phase induction motor from a single-phase network is made. The simulation model of the device created in the Matlab Simulink environment made it possible to study the electromechanical characteristics of the induction motor when operating from a single-phase network. A comparison of the characteristics of the motor during operation from a three-phase and a single-phase network is carried out. The most significant results of the work are the data obtained that the developed device can be used to start and operate a squirrel cage induction motor from a single-phase network. At the same time, the engine energy parameters change slightly.
