“…Their results showed that the consideration of temperature rise of inside air in SRM is necessary for more accurate calculations. Chang et al [20] experimentally and numerically investigates the thermal performance of a large-scale motor with a capacity of 2350 kW. Their models of the fan and motor have been implemented in a Fluent software package to predict the flow and temperature fields inside the motor.…”

a b s t r a c tIn this study, the coupled thermomagnetic system of a switched reluctance motor for cooling performance improvement has been conducted numerically. The switched reluctance motor (SRM) with output power of 3 kW and air cooling is under investigation. Aluminum cooling fins are fitted on the cooling casing of the motor in order to increase the convection surfaces. The commercial softwares used in this paper are JMAG-Designer and CFD-RC for electromagnetic field and thermal field analyzes, respectively. The electromagnetic analysis for the switched reluctance motor is obtained in advanced in order to obtain the energy losses. They can then be treated as the heat sources for heat transfer analysis. Transient solutions for the temperatures of the components in SRM are calculated during operation. The transient temperature of SRM is analyzed for both with and without cooling casing. The influence of forced convection by the internal fan of the SRM is also under investigation. Results show the numerical model is in good agreement to the real practice. The model can be used for the SRM cooling design.

“…Making effective analyzes of heat transfer, gases and liquids flows around the device, and inside of it are now possible thanks to the use of specialized computing systems based on CFD algorithms, such analysis of electric machines we can find in the works of other authors (Będkowski and Madej, 2012;Boglietti et al, 2009;Chang et al, 2010;Dorrell et al, 2006;Hongmin, 2009Hongmin, , 2010Lim et al, 2010;Szczypior and Jakubowski, 2009). The CFD analysis of impellers we can see in the works (Kelly and Gigas, 2003;Murthy et al, 2007).…”

In the article the analysis of airflow through electrical motor was conducted and optimal design solution was chosen in order to increase cooling efficiency. Numerical simulations allow to determine the areas of temperature occurrence which may have destructive influence on electrical motor parts and on its safe operation. The numerical calculations of airflow was carried out for two different types of fans as well as for two different housings. An analysis of the construction was carried out by CFD method using Autodesk Simulation CFD 2013. Community results of the analysis, we can conclude that the better solution for machines with fixed direction of rotation is to use instead of the radial the axial fan. For axial fan the motor temperature in the same condition was lower by about 5°C.

“…For this reason, many studies have been conducted to analyze the thermal characteristics of motors. Most studies have used a thermal circuit model called the thermal equivalent circuit model or the thermal network model [1] because it is less labor intensive and requires less time for computation than the computational fluid dynamics (CFD) method [2][3][4]. Li et al [5] proposed subdividing the thermal resistances of the components of a motor with complex and varying geometries.…”
