  2. 6. On design and analysis of synchronous permanent magnet machines for field-weakening operation in hybrid electric vehicles

    Author : Freddy Magnussen; Chandur Sadarangani; Barrie Mecrow; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; permanent magnet machines; field-weakening; hybrid electric vehicles; soft magnetic composites; fractional pitch concentrated windings; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : A regular vehicle of today is equipped with an internal combustion engine that runs on either gasoline or diesel, which are fossil fuels from oil reserves that are millions of years old. In all types of combustion processes carbon dioxide and several other emissions are produced. READ MORE

  4. 7. Permanent magnet motor drives with switched stator windings

    Author : Eckart Nipp; KTH; []
    Keywords : ;

    Abstract : Permanent magnet (PM) motors aretoday regarded as aninteresting solution for a wide range ofinverter-fedvariable-speed drives. The generally increasedinterest in these motors hasled to many investigations on theirfeasibility for vehicle propulsion. READ MORE

  5. 8. Permanent Magnet Machines with Air Gap Windings and Integrated Teeth Windings

    Author : Mikael C D Alatalo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent magnets; NdFeB; special windings; iron powder; synchronous machines;

    Abstract : The thesis deals with axial and radial flux permanent magnet machines with air gap windings and an integrated teeth winding. The aim is to develop a machine that produces a high torque per unit volume with as low losses as possible. READ MORE

  6. 9. A permanent magnet synchronous motor for an electric vehicle - design analysis

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

    Abstract : 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. READ MORE

  7. 10. Synchronous Machines with High-Frequency Brushless Excitation for Vehicle Applications

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

    Abstract : 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. READ MORE
