Features of the design of traction induction motors

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 active parts 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.
