Permanent magnet synchronous machines, especially interior permanent magnet (IPM) synchronous machines, are being used widely nowadays in a variety of applications. The (IPM) synchronous machine vibration and noise remain one of the critical factors to consider when some new design prototype of the machine is taken into consideration. In this paper, an efficient modular type fractional slot concentrated winding (FSCW) interior type permanent magnet synchronous motor (IPMSM) is designed, taking into account the capability of fault tolerance and open circuit fault conditions. The radial force and the associated vibration phenomenon are first investigated for the modular type (IPMSM) under normal operating conditions and then under symmetrical and asymmetrical three-phase units open circuit fault conditions. Two-dimensional (2-D) Fourier Transform has been used to investigate the relationship between the faulty operating conditions and the associated induced harmonics in the radial force density of the machine. Then, a detailed harmonic structural analysis, along with a three-dimensional (3-D) transient structural analysis, is performed on the stator of the proposed machine to investigate and verify the normal healthy design approach and the machine fault operating cases under post-fault conditions. Lastly, the vibration and noise characteristics of the prototype machine under the symmetrical and asymmetrical three-phase units’ faulty conditions are thoroughly investigated for comparison purposes over a wide operating speed range. The findings from this comparative analysis are validated through experiments, which confirm the validation of the proposed design. Moreover, the associated considerations can be used by machine designers to lower the vibration and noise level in fault-tolerant modular design machines.
