Abstract

In this paper, a 117 kW high speed permanent magnetic generator (HSPMG) was studied, and its cooling system was optimal investigated through thermal analysis and the continuous quantum ant colony optimization. Based on the determined losses distributions from the electromagnetic analysis, the analysis model for 3D temperature field analysis was established. Through the fluid-thermal analysis, the variations of heat transfer coefficients and temperatures of fluid in stator grooves along the axial direction were obtained, and so as to the 3D whole region temperature distribution in HSPMG under rated condition. Based on this, a new cooling systems with variational cross section, to made temperature distribute more evenly in HSPMG, was proposed, and the influences of groove height and the axial variation position on HSPMG temperature distributions were studied. Based on the continuous quantum ant colony optimization, a mathematical optimization model with dual objective functions and two dimensional variables for stator slots grooves optimal design was proposed, and a groove structure could make both the windings axial largest temperature and the axial temperature difference were the minimum ones was obtained.
