“…Apart from the methods exposed in Table 3, the authors of [102] propose to increase the stator yoke size as a noise and vibration reduction method, as in induction motors. In [103], the effect of the load angle is analyzed, but the authors conclude that it is difficult to find a general rule for choosing the load angle that minimizes the harmonics of the magnetic forces.…”

Electric machines are important devices that convert electrical energy into mechanical energy and are extensively used in a wide range of applications. Recent years have seen an increase in applications where electric motors are used. The frequent use of electric motors in noise-sensitive environments increases the requirements placed on electric motors intended for these applications, especially when compared to electric motors commonly used in industrial applications. This paper provides a comprehensive review of electric motor noise. Firstly, a brief introduction to noise is given. Then, the sources of electromagnetic noise and vibration in electric machines, including mechanical, aerodynamic and electromagnetic factors, are presented. Different methods such as analytical, numerical and semi-analytical for calculating electromagnetic force, natural frequencies and noise are also analyzed. Various methods for noise reduction are presented, including skewing, stator and rotor notching and slot opening width. Finally, noise measurement standards and procedures are described.

“…To avoid this, a first fault tolerant feature is obtained by using the single-layer windings concentrated on the tooth: in this way, it is possible to avoid the overlapping of the coils of the various phases, and in each slot, there will be a single winding relative to a determined phase. The use of single-layer winding concentrated on the tooth allows to reduce the length of the heads, also bringing a considerable advantage for the machine's overall dimensions [60][61][62][63]. An innovative solution to extend the drive operating range in EV would be to use multiphase motor and to dynamically modify its torque-speed ratio by changing the stator-winding configuration.…”

The rapid growth of the electric vehicle market has stimulated the attention of power electronics and electric machine experts in order to find increasingly efficient solutions to the demands of this application. The constraints of space, weight, reliability, performance, and autonomy for the power train of the electric vehicle (EV) have increased the attention of scientific research in order to find more and more appropriate technological solutions. In this chapter, it proposes a focus on the main subsystems that make a zero-emission vehicle (ZEV), examining current features and topological configurations proposed in the literature. This analysis is preliminary to the various electric vehicle architectures proposed in the final paragraph. In particular, the electric drive represents the core of the electric vehicle propulsion. It is realized by different subsystems that have a single mission: ensure the requested power/energy based on the operating condition. Particular attention will be devoted to power subsystems, which are the fundamental elements to improving the performance of the ZEV.
