Modeling of workflows of electromechanical systems with linear electromagnetic motors (LEMM) is an integral tool for their improvement in relation to discrete operations, processes and technologies of the agricultural industry or the processing of agricultural products.

(The purpose of the study) To evaluate the influence of the characteristics of a hollow (non-magnetic) axial channel in the LEMM magnetic system on the allowable changes in the output indicators of the electromechanical system by virtual simulation. (Materials and Methods) Using the specialized software COMSOL Multiphysics 4.3b (CM) Matlab, Simulink, a model of an armored cylindrical two-gap LEMM with a variable geometry of a hollow (air) axial channel, which determines the characteristics of the motor magnetic system and its output energy indicators, is obtained and analyzed.
