【 摘 要 】

In the paper a concept and physical and mathematical models of the integrated DC electrical machine for automotive vehicles with the electromechanical or hybrid-electromechanical drive is presented. The DC electrical machine under consideration is a double DC-AC/AC-DC commutator synchronous motor/generator with electronic commutators and an electromagnetic exciter on a common shaft. The paper contains a short description of the mechatronic control system of this DC electrical machine, operating both as an electromechanical motor and/or a mechanoelectrical generator. Besides, the oscillograms from the laboratory tests of this electrical machine are also presented. The analysis of the operation of this DC electrical machine is facilitated by the physical and mathematical models presented in the paper. Thanks to the use of an innovative electronic AC-DC commutator, operating as a transistor AC-DC rectifier, the energy efficiency and reliability of this electrical machine was improved during operation as a mechanoelectrical generator.
