The search for low-noise switched reluctance motor designs has encouraged this research to focus on the effects of different lamination shapes on vibration. Five different shapes are considered, with one emerging as the best candidate for the 12/8-pole combination considered. The implications of using different phase numbers in the design are also explored from a vibration and noise point of view. A prototype motor is manufactured and used for a force hammer test. The test result validates the finite-element calculations of resonant frequencies.
