Nov 11, 2021 · According to the location of permanent magnet on the rotor, the permanent magnet synchronous motor rotor mainly has two different structures: surface-mounted and buried. Due to the strength limitation of silicon steel sheets, the application of buried rotor in the high-speed field is relatively smaller than surface-mounted rotor. This paper presents a design method of the basic model of high-speed surface-mounted permanent magnet synchronous motor (SPMSM) comprehensively considering the mechanical and electromagnetic properties based on the subdomain method. In the rotor design stage, the mechanical stresses of the permanent magnet …

Permanent-Magnet Motors Wen L. Soong, Member, IEEE, and Nesimi Ertugrul, Member, IEEE Abstract— This paper compares the field-weakening perfor-mance under rated and overload conditions of synchronous reluctance and interior permanent-magnet motors against that of a baseline 2.2-kW induction machine. Four prototype rotors basedToday’s automotive industry has focused its studies on electric vehicles (EVs) or hybrid electric vehicles (HEVs) rather than gasoline-powered vehicles. For this reason, more investment has been made in electric motors with high efficiency, high torque density, and high-power factor to be used in both EVs and HEVs. In this study, an outer-rotor … ….
