Abstract
This paper investigates the vibration characteristic of a permanent magnet synchronous motor (PMSM) including magnetostriction (MS) and harmonics, which are the potential cause of additional vibration and noise from PMSM. First, a strong coupled model between the magnetic field and the mechanical deformation in the stator is built based on the piezomagnetic laws. Then, the vibration analysis of a 1.5 kW PMSM is carried out in finite element by using the model and measured MS curves. And finally, the vibration of a 1.5 kW PMSM is tested and both analysis and measured results indicate that MS and harmonics are significant and must be accounted for motor core electromagnetic design.Keywords
