A critical review on thermal management technologies for motors in electric cars

• Advanced thermal management technologies for motors in electric cars are reviewed. Air and liquid cooling methods stator, winding rotor were critically examined. Possible to enhance the heat conduction thoroughly evaluated. Pros cons of current studies presented, with suggestions future work. The development has well been regarded as a major solution tackling challenges carbon-neutrality faced by modern communities. Electric motor is certainly core most important components an car, drawn increasing attention from both industry academic society. This because required be more powerful competitive higher torque, speed power density, therefore efficient become essential maintain efficiency, durability safety. failure will result demagnetization magnets, aging insulation materials, decrease shorter lifetime even burnout motors. To enlighten research, this paper, theoretical modeling experimental investigations latest state-of-the-art various techniques, including air (natural forced cooling, impingement cooling) (water/oil jacket jet spray immersion slot channel convection presented. Meanwhile, transfer enhancement based on potting paste, guides, PCMs pipes highlighted. Following that, hybrid address extreme conditions also discussed. In last section, some given possible research applications. paper expected good reference inspiration new concepts
