“…This highlights the importance of motor design optimization not only at the high level, when all the power train is considered, taking into account the use of a gear box [9][10][11] or a complex transmission, but also at a low level, considering all the components' designs [12,13], improving the thermal management [14][15][16], use of oil spray cooling [17], advanced materials, and efficient control strategies in improving torque capacity. By addressing various aspects such as electromagnetic design [18,19], stator winding configurations, material properties, improvements in cooling, and sustainable practices, these studies contribute to the development of motors with enhanced torque performance and efficiency.…”

This study investigates the impact of temperature variations on the torque capacity of shrink-fit junctions in water-jacketed permanent magnet synchronous motors. Focusing on both baseline and improved designs; torque capacities were evaluated across a temperature range from −40 °C to 120 °C under different material conditions: Least material condition, nominal, and maximum material condition. The baseline design exhibited torque capacities from 7648 Nm to 9032 Nm at −40 °C, decreasing significantly to 549 Nm to 1533 Nm at 120 °C. The improved design showed enhanced performance, with torque capacities ranging from 8055 Nm to 9247 Nm at −40 °C and from 842 Nm to 1618 Nm at 120 °C. The maximum improvement was observed at 120 °C for least material conditions, with a 55.4% increase, and the minimum improvement at −40 °C for maximum material conditions, with a 2.4% increase. Our findings demonstrate a significant increase in torque capacity by up to 20% under varied thermal conditions. These results underscore the effectiveness of design modifications in enhancing thermal stability and torque capacity, making the improved design a more reliable choice for high-performance applications subject to significant thermal fluctuations. This research highlights the critical role of material selection, thermal management, and precise design adjustments in optimizing the performance and reliability of permanent magnet synchronous motors.

“…In the last decade, powertrain design in BEVs has witnessed significant developments due to the blossoming of new system-level design optimization strategies [25], [26] involving higher complexity and larger design space. There are many examples of design strategies focusing on the joint optimization of the system and controls, aiming at reducing energy consumption [27]- [32], thus driving down the operation costs of the vehicle. Nevertheless, none of these methods considers the trade-off between the energy efficiency of a vehicle-tailored design against the significant manufacturing cost reduction prompted by designing shared modules serving a whole family of vehicles.…”
