  We propose a parametric model of the saturated Permanent-Magnet Synchronous
Motor (PMSM) together with an estimation method of the magnetic parameters. The
model is based on an energy function which simply encompasses the saturation
effects. Injection of fast-varying pulsating voltages and measurements of the
resulting current ripples then permit to identify the magnetic parameters by
linear least squares. Experimental results on a surface-mounted PMSM and an
interoir magnet PMSM illustrate the relevance of the approach.
