Approach for the Model and Parameter Selection for the Calculation of Induction Machines

Abstract

The solution of multiphysical problems in the field of electrical machines is a complex task that involves the modeling of a wide variety of coupled physical domains. Different types of models and solution methods can be used to model and solve the individual domains. In this paper a procedure for the methodical selection of the most suitable model for a given multiphysics task is presented. Furthermore, an approach for the selection of the most suitable variable machine parameters for a design optimization is presented. The model selection is presented on the basis of the electromagnetic calculation of an induction machine. For this purpose, models of different value ranges and levels of detail, such as analytical and numerical ones, are considered. The approach of the model selection is explained and applied on the basis of a coupled electromagnetic-thermal simulation of an exemplary induction machine. The results show that the model selection presented here can be used to methodically determine the most suitable model in terms of its value range, level of detail and computational effort for a given multiphysical problem.

Thermal management of Induction Motor through the combination of air-cooling and an integrated water-cooling system

“…Yaohui et al [14] provided various guidelines for the selection of appropriate cooling methods and evaluating the performance in the early stages of design. Nell et al [15] presented coupled electromagnetic-thermal simulation using models in terms of its value range, level of detail, and computational effort for a given multiphysical problem. Zhan et al [16] and Kim et al [17] investigated the temperature distribution of an air-cooled asynchronous IM with the help of a 3D coupled field FEM.…”

The Fan Design Optimization for Totally Enclosed Type Induction Motor with Experimentally Verified CFD-Based MOGA Simulations

“…The study includes parametric design of fan, preparing the geometry for simulation, deciding solution methodology, experimentation, and optimization studies performed with CFD code ANSYS Fluent [20]. The optimization problems usually are carried out with analytical models to speed out the decision making despite there is a loss of accuracy [21,22]. On the other hand, this study uses more accurate CFD methodology.…”
