In this paper dynamic programming is proposed to estimate direct and quadrature current
harmonics that reduce magnetic noise of PMSM. This method minimizes torque ripple as …

PMSM drives are widely used in powertrains for hybrid and battery electric vehicles. Tonal
noise radiation of the drive results from magnetic force excitations in the air gap of the …

This paper analytically demonstrates how both breathing mode and torque pulsations can
be independently influenced in permanent magnet synchronous machines. This is achieved …

The harmonic current injection (HCI) can remarkably reduce the noise of the vehicular
electric drive system. However, the optimal reference harmonic current is difficult to obtain …
