Abstract
This paper presents the vibration and thermal analysis of switched reluctance hub
motor. The main vibration force is electromagnetic force mainly acted on stator. The force
and densities are obtained by the electromagnetic field analysis are applied to modal
analysis. A model of a 4phase, 8/6 switched reluctance hub motor is analyzed to obtain the
natural frequencies and deformation of the stator & rotor. The film coefficient is calculated
to find out the temperature distribution in the motor.
Indexterms: Finite element analysis, Switched Reluctance Hub Motor, Thermal, Vibration.
Conclusion
The natural vibration frequencies of the stator and rotor assembly of switched reluctance hub motor are
estimated using the three-dimensional finite element analysis. The characteristics of SRM vibration
due to the electromagnetic force were successfully analyzed by connecting the electromagnetic force
density with the mechanical vibration analysis tool. The electromagnetic force density was obtained
using the magnetic charge method and the electromagnetic finite element method. The vibration
analysis was done by the modal method and the time-stepping method. Their results of the test model
showed validity of the modal method in its accuracyThe static thermal analysis shows, how the
temperature is distributed and the maximum allowable temperature are 52.995 degree Celsius.
