  1. 6. Electric Machine Control for Energy Efficient Electric Drive Systems

    Author : Andreas Andersson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; modulation techniques; permanent magnet synchronous machine PMSM ; Energy efficiency; inverter control.; noise assessment;

    Abstract : Over the past decade, electric vehicles has increasingly become an area of attention for both academia and industry, much due to challenges such as emissions legislation and the environmental impact of the transportation sector. The absence of the broadband noise from the internal combustion engine brings new acoustic challenges for electric propulsion applications. READ MORE

  2. 7. 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

  3. 8. Modeling and Analysis of PMSM with Turn-To-Turn Fault

    Author : Joachim Härsjö; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electromagnetic forces; vibration.; inter-turn; fault; fault detection; turn-to-turn fault; Permanent magnet synchronous machine PMSM modeling;

    Abstract : Thanks to its high-torque density and high efficiency, the Permanent Magnet Synchronous Machine (PMSM) is today used in a vast range of applications, spanning from automotive to wind. Since in a PMSM the excitation field is provided by a permanent magnet instead of a coil, this machine does not have a rotor circuit and thereby the risk for electrical failures can be isolated on the stator circuit.

  4. 9. High Performance Cooling of Traction Brushless Machines

    Author : Alessandro Acquaviva; Chalmers University of Technology; []
    Keywords : energy efficiency; electrical machine design; Cooling; drivetrain system analysis.; permanent magnet synchronous machine PMSM ;

    Abstract : The work presented in this thesis covers several aspects of traction electric drive system design. Particular attention is given to the traction electrical machine with focus on the cooling solution, thermal modelling and testing. READ MORE

  5. 10. Modeling of PMSM Full Power Converter Wind Turbine with Turn-To-Turn Fault

    Author : Joachim Härsjö; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turn-to-turn; full power converter wind turbine; permanent magnet synchronous machine PMSM modeling; fault detection.; fault; Wind turbine modeling; Wind energy;

    Abstract : Over the past several years the number of renewable energy installations has shown a strong increase rate. Due to the ambition to close down fossil and nuclear power plants, this rate of increase is not expected to decline during the coming decades. In particular, wind energy represents one of the most dominant renewable energy sources. READ MORE
