Improving Thermal Analysis Accuracy of LPTN for Vehicle Claw-Pole Alternator by Calibrating Forced Convection Coefficients Based on Experimental Results

Abstract: Claw-pole alternators are particularly important for vehicle power generation due to their low cost, simple design, and mechanical robustness. High and low temperatures around vehicle claw-pole alternators (VCPAs) change their internal temperature distributions, thus thermal analysis is required for designing VCPAs. Aiming at improving the accuracy of evaluating the temperature of VCPAs, a novel lumped parameter thermal network (LPTN) is proposed to analyze the steady-state temperature of a double excitation V… Show more

“…When the PMSM is rotating, the air in the end-cavity will be driven by the viscous force, forming a strong convective heat transfer with the envelope surfaces. Therefore, the convection on these surfaces is an important heat dissipation path, especially at high-speed operation [32,33]. Reference [27] provides a detailed theoretical analysis of the free-disk flow.…”
