  2. 1. On Complex Hydrostatic Transmissions : Design of a Two-Motor Concept using Computer-Aided Development Tools

    Author : Mikael Sannelius; Jan Wikander; Stockholm Kungliga Tekniska Högskolan; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Hydrostatic drives are being used in heavy, low-speed vehicles to an ever-increasing extent. The reason for this is that a number of advantages can be achieved such as stepless gear ratios, simple power distribution and high stiffness. Increased demands have led to an interest for new conceptual designs for hydrostatic transmissions. READ MORE

  4. 2. Investigation of AC electrical machine stators with fractional conductor windings

    Author : Henrik Grop; Juliette Soulard; Yujing Liu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; windings; leakage; large machines; induction motor construction; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Industry always searches the least expensive solution for a machine design. Therefore, there is a need for integrating different customer ordered machines within the same frame, while keeping the foundation of the mechanical design constant. READ MORE

  5. 3. The control of VSC-HVDC and its use for large industrial power systems

    Author : Cuiqing Du; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VSC-HVDC; inner current controller; outer controller; PWM; dc dc converter; voltage dips; dc networks;

    Abstract : With the recent developments in semiconductors and control equipment, Voltage Source Converter based High Voltage direct Current (VSC-HVDC) has become feasible. Due to the use of VSC technology and Pulse Width Modulation (PWM), it has a number of potential advantages: short circuit current reduction; rapid, independent control of the active and reactive power, etc. READ MORE

  6. 4. Semi-deterministic numerical simulations of wear on various scales : From chemo-mechanical effects to the wear of components in orbital type hydraulic motors

    Author : Joel Furustig; Staffan Björklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : A costly effect, caused by the relative motion of machine components in contact, is wear. Solid surfaces come into contact when the lubricant film thickness is thin, resulting in locally high pressures and high wear rates. Components and machines will, due to this wear, eventually lose their functionality. READ MORE

  7. 5. Novel powertrain topologies for energy-efficient battery electric vehicles

    Author : Yu Xu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System simulation; Battery electric vehicle; Electric powertrain; Powertrain topologies; Vehicle performance; Energy efficiency;

    Abstract : The global transition towards sustainable transportation has underscored the importance of battery electric vehicles (BEVs), with a growing need for enhancement in powertrain energy efficiency to mitigate range anxiety and promote widespread adoption. In response to this need, there have been significant contributions from advancements on powertrain components, such as electric motors and inverters, towards increased energy efficiency. READ MORE
