Thermal Mapping of a High-Speed Electric Motor Used for Traction Applications and Analysis of Various Cooling Methods—A Review

This paper gives a comprehensive review of advanced cooling schemes and their applications to the permanent magnet synchronous motors (PMSMs), as well investigating electrical motor’s topologies its thermal design issues, materials performances. Particularly, electromagnetic electric performances, machine sizing, together with structural design, are given. In addition, work addresses material properties along insulation performance, which is main goal optimization. Mainly, mapping analysis provided according different methods, including air-cooling, water-cooling, oil-cooling, heat-pipe-cooling, potting silicon gelatin cooling, strategies for tubes microchannels. The most common special features demands PMSMs described in appearance failures caused by uncontrolled temperature rise. heat sources energy losses, copper loss, core loss versus motor speed, output power, analyzed. proposed methods that will achieve required transfer PMSM presented numerical simulations measurements data. A results, finite element (FEM), such Ansys CFD software, obtain high-accuracy model system revived requirements due profile flow at rotor speeds torque loads investigated. Finally, recommendations, newly developed solutions, enable it effectively redistribute transfer, increasing efficiency machine, laid out.
