Abstract:

The neutral-isolated dual three-phase permanent magnet synchronous motor (DTP-PMSM) has the fault-tolerance advantage of operating on a single three-phase winding. However, the vibration characteristics of the wingdings fault-tolerant operation mode do not inherit the low harmonic advantages of the DTP winding. This article investigates the low-frequency electromagnetic (EM) vibration of DTP-PMSM by considering winding operation modes and current harmonics. First, the winding magnetomotive force model is constructed, and harmonic analysis is performed while taking into account the winding operating mode and current harmonics. The EM force models that consider different operation winding modes are established. Then, the tooth force modulation effect of stator teeth is also taken into consideration. The influence of the winding operation mode on concentrated teeth force and EM vibration is studied. Finally, finite element analysis and experiments have been conducted to validate the analysis results.
