Calculation of the main parameters of the electric starter system of an automobile engine with a direct-on starter

The calculation of the main parameters of the electric starter system under low temperature conditions with a direct-on starter and electromagnetic excitation is proposed. Based on the similarity theory, two modes are proposed for calculation of electromechanical parameters of the starter — at maximum power and maximum efficiency of the starter. The requirement to minimize the mass of the accumulator battery and starter is taken into account.
