Scaling laws for synchronous permanent magnet machines
2015 Tenth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2015 This paper defines the scaling laws for synchronous permanent magnet machines which include three separate procedures: rewinding, axial scaling, radial scaling. The derivation of scaling relations is based on the requirement that the magnetic fields in the scaled model should be the exact images of the fields in the referent model.

Analysis of the Saliency Ratio Effect on the Output Torque and the System Efficiency in IPM Drives
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021 Permanent magnet synchronous motors (PMSM) can be classified into two groups based on the rotor saliency structure as surface mounted permanent magnet synchronous motors (SPM) and interior mounted permanent magnet synchronous motors (IPM). Saliency ratio

Influence of the Amount of Permanent-Magnet Material in Fractional-Slot Permanent-Magnet Synchronous Machines [PDF]
IEEE Transactions on Industrial Electronics, 2014 The efficiency of permanent-magnet (PM) synchronous machines with outer rotor and concentrated windings is investigated as a function of the mass of magnets used, keeping the power, volume, and mechanical air-gap thickness constant. In order to be useful for electric vehicle motors and wind turbine generators, the efficiency is computed in wide speed ...
