Pivotal technology research for the Design of High-Speed Permanent Magnet Motor Rotor Structures in Military Mobile Power Stations

Abstract

Military mobile power stations employ micro gas turbine (MGT) technology with advantages of low noise, high efficiency, minimal vibration, and reduced emissions. The high-speed permanent magnet machine is the core component. In ultra-high-speed permanent magnet motor design, two primary rotor configurations (three-layer surface-mounted and solid cylindrical rotors) are commonly studied. This paper presents a comparative design and theoretical analysis, covering rotor strength, rotor dynamics, and electromagnetic losses.
