The latest generation of traction drive systems is almost entirely equipped with asynchronous motors with power electronic converters. After years of rather sceptical approach to this technology, it is observed that these systems are gradually becoming more efficient. This fact is mainly concerned with application of maximum load of a converter and thermal load of a motor in order to create a traction characteristic compliant with demands. The paper presents rules and analytical basis for creating a traction characteristic of a vehicle. Two traction characteristics serve as an example here. Both of them are covered in the first zone of control with a constant stator flux. In the second zone, when the flux is reduced, one of these characteristics includes a section on a constant-power hyperbola, while an alternative characteristic includes a section along a line of constant current taken by the controlled machines. Both characteristics are coherent along a line of a torque limit due to the proximity of a break-down torque.
