Abstract
Heat characteristics of air vehicle motors are essential for the design of electric aircraft because of heat generation when air vehicle takes off. In this study, the numerical simulation of a water-cooled AFPM motor was carried out to obtain heat transfer characteristics. A simplified computational domain was adopted with coolant passages, and electromagnetic losses of copper, iron, and eddy currents were considered. The steady-state and incompressible flows were assumed to represent the cruising flying condition of the 150-kW power rating in the motor. The system pressure loss and coil temperature were analyzed by changing passage configurations in 4-partition cases. To resolve thermal imbalance, it is best to have the number of channel partitions increase upstream and gradually decrease as you go downstream. This study allows motor designers for air vehicles to evaluate various coolant passage configurations numerically in advance.
期刊介绍：
The aim of the Journal of Mechanical Science and Technology is to provide an international forum for the publication and dissemination of original work that contributes to the understanding of the main and related disciplines of mechanical engineering, either empirical or theoretical. The Journal covers the whole spectrum of mechanical engineering, which includes, but is not limited to, Materials and Design Engineering, Production Engineering and Fusion Technology, Dynamics, Vibration and Control, Thermal Engineering and Fluids Engineering.
Manuscripts may fall into several categories including full articles, solicited reviews or commentary, and unsolicited reviews or commentary related to the core of mechanical engineering.
