|Background and Objectives: One of the main drawbacks of switched reluctance motors (SRM) is high acoustic noise and significant research has been done to reduce it. In addition, reduction of temperature rise within the machine is usually considered as one of the most important goals of design. Therefore, a shape design method is introduced in the present paper for the SRM by which both heat transfer and acoustic noise are improved. |
Methods: For evaluation of the proposed shape design method, a simulation model based on finite element method (FEM) is also developed to predict both the temperature rise within the machine and the produced noise. The simulation model is created using ANSYS finite element (FE) package and it is build up totally as a parametric model in ANSYS parametric design language. Since the convection heat transfer coefficients depend on the temperature rise, they are determined in the developed thermal model based on an iterative algorithm.
Results: The proposed shape design method is applied to a typical 8/6 SRM and simulation results including temperature distribution in various sections of the machine, displacement of stator and sound pressure level (SPL) are presented.
Conclusion: Based on the obtained simulation results, it is illustrated that the temperature rise and the noise of the SRM could be improved significantly using the introduced shape design method.
