The paper focuses on the issue of calculating the operational characteristics of low-power asynchronous motors used in the agro-industrial complex. The substantiation of the relevance related to reducing the error while calculating the operating characteristics for the estimation and selection of a rational electric drive is given. The literature analysis presented considers the various methods of calculating the main characteristics of asynchronous motors. The equations have been compiled and solved; they help to calculate the operational characteristics without direct reference to the resistance values in the T-shaped equivalent circuit of the motor. The results of calculating the characteristics of one asynchronous motor and their comparison with the known characteristics given in the theory of electrical machines are presented. A method of engineering calculation for educational and work tasks to improve the efficiency of using electric drives is proposed. The field of further research in terms of clarifying the empirical coefficients and revising the complexity of tasks related to determining the resistance of a T-shaped equivalent circuit considering the capabilities of modern computing environments has been determined.
