Abstract: 
This paper proposes an analytical model for predicting the maximum vibration reduction level in a four-phase 8/6 switched reluctance machine (SRM) by employing vibration cancellation%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>active vibration cancellation (AVC), one of the most effective and convenient methods for reducing the vibration and acoustic noise produced by SRMs. Based on the proposed method, the factors that influence the vibration reduction level are analyzed in detail. The relationships between vibration and noise reduction levels at resonance frequency and rotor speed are presented. Moreover, it is shown that a large damping factor will lead to smaller vibration reduction level with AVC while, in contrast, a large resonance frequency will increase the vibration reduction level. Both finite element analyses and experiments were carried out on a prototype 8/6 SRM to validate the proposed method.
