The analysis of the drive characteristics of technological units in the agro-industrial complex showed that for some working bodies of machines performing translational and oscillatory movements, as well as rotary movement with a rotational speed of up to 500 min−1, special electric drives with an induction motor with an open magnetic circuit are promising. They make it possible to obtain the necessary technologically specified drive characteristics, achieve integration with the working body while excluding mechanical converters, reduce material and energy consumption, and increase the reliability of agricultural machines in general. When simulating by the method of detailed equivalent circuits of linear asynchronous motors having a primary winding with a small number of slots per pole and phase, an increase in the accuracy of numerical differentiation is achieved by decreasing the step of dividing along the coordinate, which corresponds to a conditional increase in the number of slots in the model. The analysis of the influence of the improved algorithm in the numerical study of various designs and operating modes of electric motors is carried out.
