Abstract

The electric drive with the synchronous electrical machine of independent excitation differs by high specific parameters, adaptability to manufacture, simplicity of a design, and reliability. These properties of the electric drive allow using it in heavy conditions of operation. In particular, it can be recommended to use in electrical vehicles. The electric motor for this electric drive can be executed with two separate stator windings. Therefore, there are additional benefits connected to an opportunity of change of geometry of an iron stator stamp of the given type motor. In this report, the principle of operation of the electric drive with control system is considered. The different variants of a stator design of the electrical machine are discussed. The stator design allows improve of the mass and weight parameters of the electric machine. For the offered stator designs, the comparison of specific parameters (relationship of the nominal torque to load current) is carried out. The received results of analysis are discussed.

Abstract

In this paper TNO-Advance is presented. It is built in a modular way, therefore allowing quick assembling of specific vehicle configurations and easy integration of new component models and future evolutions of existing models. Its entensive library is built in Matlab/Simulink, taking advantage of its flexible and open architecture, the effective mathematical libraries and real-time application possibilities. TNO-Advance allows not only to develop, analyze and evaluate both chassis and powertrain systems, but also the interactions between them. All car suspensions can be represented and conventional as well as electric and hybrid electric vehicle powertrains. By applying the fast control options of Matlab/Simulink, chassis and powertrain controllers can be developed, as well as tested on robustness. Even interactions between vehiclesq, i.e. platooning, or new road transport systems, i.e. Intelligent Transport Systems and automatically guided vehicles, can be studied effectively.
