  2. 1. Design and analysis of a fault-tolerant fractional slot PMSM for a vehicle application

    Author : Christian Dubar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saturation; Permanentmagnet synchronousmachine PMSM ; Fault-tolerance; windings; Concentrated; Fractional slot; Unbalanced operation;

    Abstract : 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. READ MORE

  4. 2. High Performance Cooling Traction Brushless Machine Design for Mass Production

    Author : Alessandro Acquaviva; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanentmagnet synchronous machine PMSM ; energy efficiency; Cooling; electrical machine design;

    Abstract : In the last few years electric vehicles (EVs) are coming on the market. The shift from niche market to main stream is challenging. It took many years to reach the current internal combustion engine quality in the manufacturing process. READ MORE

  5. 3. System Aspects of Marine Current Energy Conversion

    Author : Katarina Yuen; Uppsala universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Free-flowing water currents such as tides and unregulated water courses could contribute to world electricity production given the emergence of robust technical solutions for extracting the energy. At Uppsala University, a concept for converting water currents to electricity using a vertical axis turbine with fixed blade pitch and a direct drive permanentmagnet generator is studied. READ MORE

  6. 4. 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. 5. Analysis and Control Aspects of a PMSynRel Drive in a Hybrid Electric Vehicle Application

    Author : Shuang Zhao; Chandur Sadarangani; Zi-Qiang Zhu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active damping control; electric drive; electric vehicle; hybrid electric vehicle; integrated charger; permanent-magnet assisted synchronous reluctance machine; position estimation; sensorless control;

    Abstract : This thesis deals withmodeling and control of an electric drive equipped with a permanentmagnet assisted synchronous reluctance (PMSynRel) machine for a plug-in hybrid electric vehicle application.In the first part of the thesis, a special use of the PMSynRel machine in consideration, known as an integrated charger concept, is investigated.
