  1. 1. Induction bearings

    Author : Torbjörn A. Lembke; KTH; []
    Keywords : ;

    Abstract : A self stabilizing homopolar induction bearing withintegrated touch down bearings has been developed forhigh-speed applications like flywheels, small gas turbines andcompact vacuum cleaners.Stability is achieved without any control electronics thanksto stabilizing eddy currents induced by permanent magnets.

  2. 2. Kinetic Energy Storage and Magnetic Bearings : for Vehicular Applications

    Author : Johan Abrahamsson; Hans Bernhoff; Urban Lundin; Richard Magdalena Stephan; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; flywheel; magnetic bearing; energy storage; electric vehicle; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : One of the main challenges in order to make electric cars competitive with gas-powered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficientlyhigh specific energy, their applicability is limited due to low specific power. READ MORE

  5. 5. Electrified Integrated Kinetic Energy Storage

    Author : Magnus Hedlund; Hans Bernhoff; Markus Mueller; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; flywheel energy storage; magnetic bearings; carbon composite; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The electric car is a technically efficient driveline, although it is demanding in terms of the primary energy source. Most trips are below 50 km and the mean power required for maintaining speed is quite low, but the system has to be able to both provide long range and high maximum power for acceleration. READ MORE
