The purpose of this work is to build the analytical improved (with resistances estimation) real time computation reference inputs for rotor flux and torque in vector control system an induction motor a traction electric drive. must maximize electromagnetic conditions voltage source instability, particularly magnetic field weakening mode. conventional way mode form coupling task inversely propor...

Electric vehicle (EV) appears to be one of the viable solutions for the growing concerns for environmental protection and the fast rate of depletion of world fuel oil supply. EV can become a viable alternative to the internal combustion engine only if they are able to meet certain reliability, safety, performance, and cost criteria. In addition, electrical vehicles have serious disadvantages be...

tight market windows in the rapidly evolving HEV and EV markets. Integrated multiphysics simulation technology helps to address these challenges by enabling engineers to rapidly evaluate — prior to physical prototyping — functionality, performance and cost of a wide range of design alternatives. This approach makes it possible to optimize traction motor design performance in a fraction of the t...

Methods: Diagnostic complexes determine technical state depots. In order approaches choice and evaluation power source parameters vibroacoustic blocks depot analysis designi...

Axial flux electric motors have received a lot of attention in recent years due to successful implementations industrial or traction applications. Particularly, axial permanent magnet synchronous (AFPMSM) can be an attractive choice case high torque-density requirements when the drive environment (packaging) is geometrically limited disc-shaped motor. However, compared radial motors, machine mo...
