On the issue of contactless alternators on movable objects

Abstract

BACKGROUND: This article discusses automotive inductor alternators of domestic and foreign production with different power and design. A comparative analysis of inductor alternators according to the main electromagnetic parameters and design is carried out. Based on the results of the comparative analysis, conclusions are drawn about the competitiveness of domestic inductor alternators and their superiority over foreign analogues.

AIM: Research and comparative analysis of tractor inductor alternators 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 method with the Blondel diagram is used to calculate the current-speed curve.

RESULTS: A review and comparative analysis of automotive inductor alternators of domestic and foreign production, with various magnetic systems and design, is carried out. The advantages and disadvantages of the magnetic circuit of inductor alternators of both domestic and foreign production are determined and given in comparative tables and current-speed curves. The optimal design of the inductor alternator with the most effective technical and economic indicators was chosen to perform the calculation.

CONCLUSIONS: The calculation of the magnetic circuit and idling characteristics of the 11.3701 three-phase single-pole, single-pack inductor generator with a classical toothed zone and a two-half-period rectifier is carried out. The calculation of the current-velocity curve was performed using the well-known method with the Blondel diagram and the method of successive approximations using iterations.
