    Sammanfattning : The permanent magnet synchronous motor (PMSM) is an interesting alternative for an electric motor drive system in automotive applications, due to to the high efficiency requirement; as only a limited amount of energy can be stored in the relatively expensive battery. Another advantage is the high torque and power density a PMSM can achieve since it is very important to save especially space but also weight in vehicle applications. LÄS MER

  4. 3. A permanent magnet synchronous motor for an electric vehicle - design analysis

    Författare :Yung-Kang Chin; KTH; []
    Nyckelord :constant power speed range; electric vehicles; field-weakening; reference flux linkage;

    Sammanfattning : This thesis presents the study and the design analysis of apermanent magnet synchronous motor (PMSM) for the tractionapplication of an electric vehicle. An existing inductiontraction motor for an electric forklift benchmarks the expectedperformances of the proposed PMSM design. LÄS MER
