Use of transformers as differentiating elements of a tachometric device of a follow-up valve electric drive with a sine-cosine rotor position sensor of the electric motor was justified. A possibility of linearization of the tachometric device’s output characteristic by connection of balancing capacitors to secondary windings of differentiating transformers was considered in this work. Capacity of balancing capacitors was determined. The author proposes a method for analyzing output voltage ripple of a tachometric device with differentiating transformers and for determination of their relative amplitude. The results of experimental researches of a tachometric device with differentiating transformers are also presented in this paper.

In this article the author proves expediency of application of a traction generator based on a nine-phase synchronous electric machine with permanent magnets, closed-coil winding and an uncontrolled rectifier in a complete set of traction electric equipment of the supersize vehicles. By means of developed simulation models of a traction generator and a test bench, influence of switching processes in the generator rectifier on its static and dynamic characteristics was investigated. Analysis of obtained simulation results and results of development tests was carried out, and the obtained results are provided in this article. Recommendations on use of simulation models during designing and modeling of a combined action of the traction generator and internal combustion engine are drawn.
