A new strategy is proposed here for the diagnosis of asymmetric demagnetisation in permanent magnet synchronous machines. The strategy is based on the measuring of the voltage at the midpoint of the windings within a phase. ...

A strategy for the detection of bearing faults in variable speed wind turbines with permanent magnet synchronous machines is presented in this paper. The strategy consists on processing the measured vibration signals as ...

The effects of asymmetrical magnet faults on the rotor of permanent magnet synchronous machines (PMSM) are analyzed in the present work. Two different stator winding configurations, series and parallel connected windings, ...

An analytical model for permanent magnet synchronous machines with demagnetization faults is proposed. Using this model, the effects of fault on the induced EMF for different winding configurations are analyzed. The results ...

Owing to the competitive advantages of cost reduction, system downsizing, and reliability enhancement, position sensorless control methods for permanent magnet synchronous machine drives have drawn increasing attention ...

This paper presents a method for electromagnetic torque ripple and copper losses reduction in (non-sinusoidal or trapezoidal) surface-mount permanent magnet synchronous machines (SM-PMSM). The method is based on an extension ...

This paper proposes a model predictive speed control of a permanent magnet synchronous machine (PMSM). The control scheme has a cascade architecture, where the inner loop uses a finite set model predictive control scheme ...

This master dissertation presents contributions to the study, development, and design of adaptive observers applied to the estimation of rotor speed of permanentes magnet synchronous machines. The rst proposed technique ...
