BACKGROUND: This article discusses automotive inductor generators of domestic and foreign production with different power and design. A comparative analysis of inductor generators according to the main electromagnetic parameters and design designs is carried out. Based on the results of the comparative analysis, conclusions are drawn about the competitiveness of domestic inductor generators and their superiority over foreign analogues. AIMS: research and comparative analysis of tractor inductor generators in order to determine the optimal design, as well as the main characteristics and parameters. METHODS: The calculation of the magnetic circuit and the idling characteristic is based on the method of successive approximations using iterations. A well-known technique using the Blondel diagram is used to calculate the current-speed characteristic. RESULTS: A review and comparative analysis of automotive inductor generators of domestic and foreign production, with various magnetic systems and constructive equipment, is carried out. The advantages and disadvantages of the magnetic circuit of inductor generators of both domestic and foreign production are determined, which are reflected in comparative tables and current-speed characteristics. To carry out the calculation, the optimal design of the inductor generator with the most effective technical and economic indicators was chosen. Conclusions: The calculation of a three-phase single-pole, single-pack inductor generator 11.3701 with a classical toothed zone and a two-half-period rectifier is carried out. The calculation of the magnetic circuit and the idling characteristics was carried out by the method of successive approximations using iterations. The calculation of the current-velocity characteristic was performed using a well-known technique using the Blondel diagram.
