  1. 21. Modelling of six-wheeled electric transmission terrain vehicle

    Författare :Olof Noréus; Annika Stensson Trigell; Karl Magnus Gäfvert; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : In vehicles with electric transmission and independent wheel stations, it is possible to have a possibility to control propulsion, steering and suspension individually for each wheel. This makes it possible to improve mobility, performance and driving safety. LÄS MER

  3. 22. Automotive Remanufacturing in a Changing Market : Challenges and Opportunities in a market with a growing share of electric cars

    Författare :Robert Casper; Erik Sundin; Mats Björkman; Amir Rashid; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Remanufacturing Process Challenges and Improvements; Process Efficiency; Automotive Part Remanufacturing and Reuse; Internal Combustion Engines ICE ; Battery Electric Vehicles BEV ; Cirkulär Ekonomi; Återtillverkning; Återtillverkningsprocesser; Processeffektivitet; Bilindustri; Förbränningsmotorer; Elbilar; Elektrifiering;

    Sammanfattning : This doctoral thesis deals with closed-loop supply chains, which include remanufacturing. Remanufacturing can be described as an industrial process to bring back a used good into an “as-good-as-new” condition. Furthermore, focus is put on one of the largest global industry sectors: the automotive industry. LÄS MER

  4. 23. A Permanent Magnet Traction Motor for Electric Forklifts : Design and Iron Loss Analysis with Experimental Verifications

    Författare :Yung-Kang Robert Chin; Chandur Sadarangani; Fabio Crescimbini; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : This thesis presents the design analysis of a permanent magnet synchronous motor (PMSM) for the traction application in electric forklifts. Within the scope of the study, an existing induction traction motor for electric forklifts benchmarks the expected performances of the proposed PMSM designs, as design specifications. LÄS MER

  5. 24. Distributed Control of Electric Drive Systems via Ethernet

    Författare :Lilantha Samaranayake; Chandur Sadarangani; Alexander Medvedev; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive sampling scheme; control delay; delay compensation; distributed control systems; Ethernet; Ethernet ready sensor actuator module; sampling period; Electrical engineering; Elektroteknik;

    Sammanfattning : This thesis is on adapting standard Switched Ethernet for distributed control applications in electric drive systems. The critical issue of Ethernet here is to provide services to real-time applications. LÄS MER

  7. 25. Assessment and control of tonal components in electric vehicles

    Författare :David Lennström; Etienne Parizet; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : New challenges arise for noise, vibration and harshness (NVH) engineers when electric motors are introduced into cars traditionally powered by internal combustion engines (ICE). The noise signature from an electric traction motor is characterized by speed-dependent high frequency tonal components due to electro-magnetic excitation. LÄS MER
