  7. 20. Design of a Synchronous Reluctance Motor Assisted with Permanent Magnets for Pump Applications

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

    Författare :Adrian Ortega Dulanto; [2015]
    Nyckelord :Demagnetization study; efficiency; FEM; parametric study; Permanent-Magnet Assisted Synchronous Reluctance Motor; prototype;

    Sammanfattning : This Master thesis focuses on the design of a high efficiency Permanent-Magnet-Assisted Synchronous Reluctance Motor (PMASynRM) intended for pump applications. The new motor is designed to replace an existing Induction Motor (IM) in a pump product. The basic principles of SynRM, and PMASynRM Motors and a good analytical model were introduced. LÄS MER
