Advances in Thermal Management Technologies of Electrical Machines

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