induction motors - Opis:
- For railway vehicles with electric traction drives with induction motors, it is necessary to determine traction characteristic curves of such a vehicle. Such a traction characteristic curve is essential to calculate All the static and dynamic parameters of the vehicle, such as maximum acceleration, maximum speed, time of approaching the maximum speed, and many others. For this purpose, one needs the original torque - speed characteristic of applied traction motors as well as both the wheel - rail adhesion coefficient and the train resistance as functions of the speed of the vehicle. It was taken into account of the three regions on the traction characteristic curve of the traction drive: the constant torque, the constant power, and the weakened power regions. Various formulas for the wheel - rail adhesion coefficient were compared and discussed. The metod for considering the dispersion of real values of the adhesion coefficient was considered. Making use of all considerations, the resultant traction characteristic curves were created.
