“…Another important requirement for the optimal HEV's operation is the minimization of motor's losses during different driving cycles or the overall profile of the HEV [26]. It is evident that design parameters that are optimized for one average assumed drive cycle are not necessarily optimal when an alternative use of the vehicle is carried out [27].…”

Throughout the last few years, permanent magnet synchronous motors have been proven suitable candidates for hybrid electric vehicles (HEVs). Among them, the outer rotor topology with surface mounted magnets and concentrated windings seems to be very promising and has not been extensively investigated in literature. In this study, an overall optimization and modelling procedure is proposed for the design and operational assessment of high-power density direct-drive in-wheel motors, targeted towards a light HEV application. The analytical model of an HEV's subsystems is then implemented for a more accurate evaluation of overall powertrain performance. Furthermore, a simple but effective cooling system configuration, which is taking into account the specific problem requirements, is also proposed.

For continuous-duty applications, electric motors are conventionally designed to experience a hot-spot temperature below their insulation thermal class. When frequent overloads are required, a safety temperature-margin is considered at the machine's design stage, so that the insulation is not thermally overstressed. This procedure leads to an increment of the machine's size, with a consequent power density reduction. Indeed, lower thermal loadings are obtained by decreasing the winding current density by e.g. increasing the equivalent cross-sectional area of conductors. For some applications, it is possible to avoid the "over-engineering", but the reliability level might be compromised. This work addresses the subject of thermal overload capability in electrical machines, combining elements of thermal analysis, reliability and physics of failure. A novel design methodology is introduced and validated by means of thermal accelerated lifetime tests on winding specimens. The proposed approach is used for redesigning a brushless DC motor achieving excellent results in terms of power density boost.
