Abstract :
This work presents the development of a CFD methodology to evaluate the distribution of the airflow around the end winding of an asynchronous motor. This process was assisted by an experimental device that was designed and developed in order to consider a number of geometric simplifications aiming at the validation of the CFD model. The problems of numerical convergence in both steady-state and transient regimes are discussed in this work.
