“…First of all, the distribution of the winding conductors is defined according to the star of slots method [29]. Employing the winding periodicity (t p ), which is the greatest common divisor (GCD) of the number of pole pairs and the number of slots, the number of pole pairs in a periodicity (p ) and the number of slots in a periodicity (Q s ) are calculated.…”

The use of electric motors, and particularly, Permanent Magnet Synchronous Motors, is increasing in recent years, and their vibration response is one of the most crucial aspects regarding their behaviour. Thus, the reduction in vibrations is one of the key objectives when optimizing electric motors. In an initial design state, the influence of the main design parameters on the behaviour of the machines is not always clear. For that reason, this work presents a global sensitivity analysis procedure that allows identifying the most influential design parameters and determining guidelines to optimize the design of Permanent Magnet Synchronous Motors. First, the analytical calculations employed to estimate the electromagnetic torque and the vibration response of the machine are described. Then, the sensitivity analysis procedure, based on the Monte Carlo method, is presented, and the conditions to apply the method successfully and accurately are analysed. Finally, the sensitivity analysis is performed for a particular electric motor design, and some general design guidelines are deduced, which can be extrapolated to similar machines.

“…In recent decades, the use of PMSM is constantly increasing in many industrial and energy fields, such as rail and aeronautic transport, electric vehicles, electric traction, electric propulsion and wind farms. These motors, associated with inverters, have a more compact structure, a high specific power, and a higher dynamic response compared to conventional structures (direct current motors, synchronous wound rotor motors or induction motors) [1][2][3][4][5][6][7][8].…”

“…The most precise method consists in defining the real geometry of the PMSM studied. The Maxwell equations associated with the behavior laws of the materials used are then solved using numerical methods (Finite Elements Methods) [5,7,14]. Unfortunately, the major drawback of this method is the computation time, which can be quite long, especially for a finer mesh or a strong coupling between the different physical domains.…”

This paper proposes the development of a new mathematical model dedicated to the diagnostic of the partial Demagnetization Fault (DF) in Permanent Magnet Synchronous Motor (PMSM). To do this, an extension of the Modified Winding Function Approach (MWFA) is proposed to accurately take into account the air gap asymmetry caused by the Demagnetization Fault (DF) in the PMSM inductances calculation. The calculated inductances are then used in the magnetically coupled electrical circuit model to simulate the PMSM behavior in the different operating modes. Finally, a diagnostic method based on the stator current spectral analysis is used to highlight the PMSM stator current spectral content in the various operating modes (with and without Demagnetization Fault).
