Abstract :
This paper aims to characterize the behavior of both radial and tangential components of force in a 5-phase PMSM. Energy conversion has been investigated at a microscopic level and the effects of q- and d-components of current on generated torque have been investigated along with their influence on the radial vibrations. Further, magnetic field reconstruction is employed in an attempt to evaluate acoustic noise and vibration in the PMSM, which remains a main concern in various automotive and military applications
