Designs and parameters of asynchronous electric motors for agricultural needs

Abstract

The purpose of this study is to analyse the design features of asynchronous electric motors used in the agro-industrial sector in the processing of oilseeds. The paper is aimed at identifying optimal technical solutions to ensure high energy efficiency, reliability, and durability of units in difficult operating conditions. The methodology of the study is based on a theoretical analysis of literature sources and a comparative analysis of the design parameters of engines of different power. In experimental studies, thermal conditions are measured, and the influence of variable load conditions on the technical characteristics of electric motors is evaluated. The results obtained indicate a substantial influence of the rotor geometry, winding insulation class, and housing design on the performance of the units. It is determined that medium-power engines equipped with efficient cooling and protection systems against aggressive environments demonstrate stable operation under short-term overloads. Analysis of heat sink and wear resistance indicators allows determining the optimal design parameters that help reduce energy losses and increase the reliability of units.
