Summary:In electric machines, the main sources of noise, vibration, and harshness (NVH) are electromagnetic and structural origin. In this study, the Electromagnetic and NVH performance of dual three-phase machine in two modes of operation has been investigated. One mode is the excitation of two sets of three-phase winding where these two sets are shifted by 30 degrees. The other mode is the excitation of only one set of three-phase winding where the other set is kept deactivated, which is referred to as a single three-phase winding configuration. The analysis reveals that a single three-phase configuration produces a significantly high torque ripple and subsequently high NVH compared to a dual three-phase one as the rotor experiences unbalanced forces. Radial pressure and force are calculated from Electromagnetic Finite Element Analysis (FEA), and acceleration is predicted through structural FEA for dual three-phase PMSMs in both operating modes.
