Abstract :
Harmonics in the electromagnetic torque can be a source of concern in interior permanent magnet synchronous machine (IPMSM) drives. The harmonics are created by nonidealities in the electromagnetic fields produced by the magnets and the stator excitation. They lead to vibration that can cause premature wear of the drivetrain components as well as acoustic noise that may be bothersome to users. In this research, a feedback-based currentcontrol scheme has been developed to mitigate the torque harmonics.
