“…Generally, centrifugal, axial fans and piezoelectric fan have been used or tested for motors [123,124]. The selection and optimization of the fans' structure are important factors to enhance the cooling, as indicated by the contribution of Chen et al [125], Nakahama et al [39], and Kim et al [126].…”

“…The results in [21] demonstrated that the fins can neither be designed too thick nor too thin, because a large portion of the cooling channel is blocked in thick fins while thin fins will reduce the cross-sectional area available for air flow. Piezoelectric Fan Cooling was developed in [22,23], which indicated that an average convective heat transfer coefficient enhancement of 364.8% on the fin base and an enhancement of 53.6% on each of the fin side walls were attainable.…”

Given the fact that the operation of electrical machines generates various loss components that finally become heat, developing advanced thermal management technologies is essential to control temperature increases and to guarantee safe operations. Meanwhile, the armature winding can stand larger currents when the machines are equipped with advanced cooling systems, which directly improves torque/power densities. This paper aims to provide a systematic review of the latest developments of advanced thermal management technologies of electrical machines. According to different heat dissipation mechanisms, the cooling systems studied in this paper are categorized into five major types: enclosed housing cooling, enhanced conductive cooling, embedded heat pipe cooling, direct oil cooling, and enhanced rotor cooling. The advantages and disadvantages of these cooling systems are researched and compared comprehensively. This study contributes to the revelation of insights on the thermal management of electrical machines and offers good guidance for the thermal management of electrical machines.

“…Other special cooling techniques have been developed. Piezoelectric fans are implemented to replace liquid cooling systems to improve fault‐tolerance and reliability [78]. Temperature sensitive ferrofluids are used as cooling and dielectric medium for end winding to avoid extra complexity and costs in liquid cooling systems including deionised water, pumping system, filters, instrumentation and so on [79].…”

Electric machines have broadly been used in many industries including the transportation industry. With the evolving trend of electrification in transportation, electric machines with higher power density and higher efficiency are demanded and, thus, more stringent thermal management requirements are needed for electrified vehicle applications. This study comprehensively presents various important aspects of thermal management in electric machines with the main focus on transportation applications. Design considerations, challenges, and methods for enhanced thermal management are discussed. Fundamental thermal properties of common materials are presented and sources of losses in various parts of machines are explained. Furthermore, typical cooling techniques and thermal analysis approaches for electric machines are reviewed in detail. This study will serve as a reference guideline for machine designers, who are interested in thermal management, and for thermal researchers working on electric machines.
