Simulation of dynamical processes specific to asynchronous traction motors

SPEEDAM 2010, 2010
In case of motors working in complex dynamical regimes, evaluation by modeling and simulation of electromagnetic and mechanical stresses, becomes a mandatory objective. In the present paper, means of investigation are presented and, on this basis, some dynamical processes of traction asynchronous motors are analyzed.

Calculation of asynchronous traction motor start-up characteristics by FEM method

International Symposium on Power Electronics Power Electronics, Electrical Drives, Automation and Motion, 2012
2D and 3D calculation of squirrel-cage traction motor start-up characteristics at rated voltage and frequency have been performed by using a numerical FEM based program. From the equivalent circuit parameters, which are obtained by analytical calculation, a simulation of a start-up using an analytical dynamic model was performed.

The Importance of the Cross Geometry over the Optimal Design of Asynchronous Traction Motors

2020 International Conference and Exposition on Electrical And Power Engineering (EPE), 2020
In electric traction, the motors that drive the railway vehicles consume a lot of active and reactive electricity, so the operating costs are high. Therefore, a reduction of the operating cost is proposed, through an optimal design of the asynchronous traction motors. This is a very difficult problem, assuming the knowledge of the operating conditions,

3-phase asynchronous motors for traction drives on BR

Proceedings of the 1991 IEEE/ASME Joint Railroad Conference, 2002
The simplicity and robustness of the three-phase asynchronous motor make it attractive for traction applications. Attempts to use it go back to the turn of the century. It was, however, the appearance of the microprocessor and high-power GTO that made the three-phase package attractive for general applications.

Research on the Directional Control of Direct Magnetic Field of the Locomotive Asynchronous Traction Motor

2019
The directional control of the direct magnetic fields of the induction motor can improve the dynamic response speed of the motor, and its flux observation link is located in the feedback channel, so it has better parameter insensitivity than the indirect field-oriented control.
