Abstract

The main disadvantage of Switched Reluctance Motor (SRM) is Vibration produced in it. This paper presents the vibration analysis of Switched Reluctance HUB Motor. The main source of vibration is electromagnetic force. The force value is obtained by the FE magnetic field analysis and applied to the Finite Element (FE) mechanical modal analysis. A numerical model of 4-phase 8/6 SR Hub motor is tested to attain the natural frequencies and deformation of the stator. For different designs and modes of stator, natural frequencies are obtained in modal analysis. Transient or Harmonic Analysis is also accomplished to compare its results with the ones obtained using the modal method.

Abstract

This paper presents the flow analysis of novel pole shape switched reluctance hub motor. The novel pole shape improves the machine performance and the flow analysis improves the temperature distribution inside the novel pole shape switched reluctance hub motor. A computational fluid dynamics (CFD) is a good technique for the evaluation of fluid flow, the "fluid" that flows inside a rotating electric machine is the air, which is highly turbulent when the rotor starts rotation. To evaluate the accurate simulation of heat distribution, the results of CFD analysis are used.

Keywords
