The work considers technical requirements for traction motors and motor-generators and optimization of active parts of asynchronous traction motors under the "torque/mass" and "torque/losses" criteria, and analyzes the influence of dimensions and other parameters of motor activeparts on motor specifications, along with the issues of coordinating the characteristics of traction motors with those of power converters, Prototypes of asynchronous traction motors with optimized geometry of active parts are presented, as well as their use in the vehicles, designed by the RUSELPROM Concern. The calculation model allows obtaining the results, which are far from being obvious. We have grounds to express the confidence that the methods based on the above approaches will allow essentially increasing the designing quality of asynchronous motors, including traction ones. We can hope that after mastering the procedures of expert's computer optimization, these methods will make the basis of the engineering techniques for electromagnetic calculation and designing the electromechanical devices of hybrid vehicles. Development of such computer program and a library of computerbased calculations is the objective of the forthcoming researches. It is clear that at designing particular electric machines, a great (and undoubtedly, the decisive) role will be given to design restrictions (the values of the gap and yoke; the depth and shape of the groove; the strength considerations; the specific losses, etc.) and parameters of used materials. However, we can express confidence that the knowledge of the limiting achievable parameters will be helpful and allow evaluating the "cost" of this or that design restriction. Participation of an expert id expedient at all the estimation phases; in particular, at the first stage of optimization of electric motors, the expert can influence the selection of the geometry of the pole pitch by varying the weight coefficients and by establishing the design restrictions on variation ranges of geometrical dimensions. The conclusions are based on and confirmed by the calculation optimization models of asynchronous electric machines with a short-circuited rotor, which take into account many factors, such as the grade of the electrotechnical steel, saturation, hysteresis and losses from eddy currents, characteristics of conductive materials, the current displacement effect, etc. The obtained qualitative results are, most probably, valid also for other types of electric machines, naturally, under different parameter values. The optimization of electromechanical devices makes it possible to essentially improve vehicle specifications; and in a number of cases - also qualitatively improving their parameters of controllability, passing capacity and achievement of the required operational characteristics. We can hope that after mastering the procedures of the computer-based expert's optimization, these methods will make the basis of the process of electromagnetic calculation and designing of electromechanical devices of hybrid vehicles. The creation of such software and the library of computer-based calculations is the task for future researches. The obtained qualitative results are, most probably, valid also for other types of electric machines, naturally, under different parameter values.
