The performance of the permanent magnet synchronous machines depends on the torque ripple and radial forces acting on its shaft and stator frame. There are two major ways to treat the undesirable torque ripples. In the first group of the methods machine design issues is considered. The second group considers optimal excitation of the machine so that the resulting performance is acceptable. In this...
In recent years, several control methods have been proposed to reduce the torque ripple produced by permanent magnet synchronous machines [sinusoidal and trapezoidal back electromotive force (EMF)]. In these approaches, a drive system is used to control current harmonics based upon measured machine parameters or measured torque ripple. In general, the methods presented have utilized high-precision...
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...
