High power density variable speed traction motor

Koushan, Salar
The purpose of this thesis is to develop, manufacture, and test a new traction induction motor that is capable of meeting the desired characteristics, limits and expectations set by the traction application in which it will be utilized. For achieving this goal, initially the finite element (FE) calculation techniques and model accuracy is verified by modeling a reference test motor in a FE environment and verifying the loss data and performance of the motor with measurement data. After testing and modelling the reference test motor, several guidelines and criteria are defined to further help the design process and to ensure the accuracy of the results obtained. In the next step, an initial FE design is developed based on the desired motor rating, and by following the established design criteria (motor’s magnetic loading, electrical loading, current density, and cooling capacity of the motor). Through iterative analytical modification, initial FE model, is improved and an optimum design is selected. Finally, based on the developed model, the motor is manufactured and is verified through comparing the FE data with the test results. Additionally, manufactured motor is tested to ensure that the motor is capable of providing the required performance
