Electric aircraft propulsion is a growing research area that looks into achieving through fully electric or hybrid systems while low emissions. The system-level benefit gained by different and hybrid-electric schemes depends heavily on the performance of components in drive-train, including motor, gear box, motor drive, protection systems, as well thermal management system. When comparing topologies, it important to understand measures such efficiency specific power drive system level. Many...
Electric propulsion systems for aircraft require electric motors with high power density and efficiency. This paper presents the design analysis of a 300 kW slotless permanent magnet synchronous motor propulsion. The machine consists Halbach PM-array structure an air-cooled stator custom litz wire formed using cured, ceramic-filled resin. proposed is designed considering multi-physics performance based on electromagnetic field, thermal mechanical analysis. However, resulting specifications...

An important thrust in current aerospace research is aircraft electrification, including propulsion system electrification. For an electrified to provide net benefit over conventional propulsion, the electrical systems must meet high specific power, power density, and efficiency standards. This paper presents experimental validation of components a megawatt scale permanent magnet synchronous motor targeting density 13 kW/kg 96% efficiency. demonstrates that it possible build stator...
High speed and high rotor tip-speed, in particular, combined with magnetic electrical loading, are key enablers for obtaining specific power electric machines. The described this paper pushes the tip to about 80% of sound. An outer design a carbon-fiber retaining ring on diameter (OD) was chosen maintain loading airgap while ensuring structural integrity at speed. To achieve manufactural feasibility, cantilevered structure proposed suspend around stator. This architecture introduces...
Typically, HVAC systems consume a significant amount of energy in both commercial and domestic buildings. The major part consumed an system is by the compressor motor, which operates at high shaft speeds direct drive systems. efficiency motor cost effectiveness are two factors determining type to be used chiller applications. electrical factor decided material cost, manufacturing complexity, power switching frequency. Since chillers not continuously run rated power, integrated load value...
