  1. 1. Design and Control of Electrically Excited Synchronous Machines for Vehicle Applications

    Författare :Junfei Tang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Machine Modeling; Electric Machine Design; Brushless Excitation; Electric Machine Control; Electric Drives; Electrically Excited Synchronous Machines;

    Sammanfattning : Electrically excited synchronous machines (EESMs) are becoming an alternative to permanent magnet synchronous machines (PMSMs) in electric vehicles (EVs). This mainly attributes to the zero usage of rare-earth materials, as well as the ability to achieve high starting torque, the effectiveness to do field weakening and the flexibility to adjust power factor provided by EESMs. LÄS MER

    Sammanfattning : Electrically excited synchronous machines (EESM) are becoming an alternative to permanent magnet synchronous machines (PMSM) in electric vehicle (EV) applications. This mainly attributes to the zero usage of rare-earth material as well as the capabilities of high starting torque and good field weakening provided by EESM. LÄS MER
