  2. 1. Analysis of an innovative design of an axial flux Torus-machine

    Author : Maddalena Cirani; KTH; []
    Keywords : ;

    Abstract : The high compactness of axialflux permanent magnet (AFPM) machines compared with theconventional induction, DC and radial flux permanent magnet(RFPM) machines, renders this machine-topology particularlysuitable to be integrated in a system for hybrid electricvehicles (HEVs). Indeed, due to the limited space inside thevehicle, the considerable reduction in volume and weightoffered by AFPM machines is of major importance. READ MORE

  4. 2. Design and Evaluation of a Compact 15 kW PM Integral Motor

    Author : Peter Thelin; KTH; []
    Keywords : integral motor; integrated motor drive; PM motor; PMSM; compact motor; filter coil; airgap flux density; axial leakage;

    Abstract : This thesis deals with the integral motor of tomorrow, and particularly with a variable speed, sensorless permanent magnet synchronous motor with an integrated converter. The rated power is 15 kW at 1500 r/min. The outer dimensions are approximately the same as for the equivalent standard induction motor.Control strategies for pumps and fans, i. READ MORE

  5. 3. A Low-Leakage Linear Transverse-Flux Machine for a Free-Piston Generator

    Author : Waqas Arshad; KTH; []
    Keywords : Free-piston generators; linear machines; transverse-flux machines; hybrid vehicles; electrical machines design;

    Abstract : The presented work is about a new low-leakage lineartransverse-flux electrical machine.The machine is dimensionedfor a free-piston generator. The intended application is inseries-hybrid vehicles. The free-piston generator is anintegration of a free-piston combustion engine with a linearelectrical machine. READ MORE

  6. 4. On analytical modeling and design of a novel transverse flux generator for offshore wind turbines

    Author : Dmitry Svechkarenko; Chandur Sadarangani; Waqas Arshad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transverse flux machines; permanent magnet machines; direct-driven gen- erator; offshore wind turbine; renewable energy; global warming; Electrical engineering; Elektroteknik;

    Abstract : The object of this thesis is to develop a cost effective direct-driven wind generator suited for offshore wind turbines. As the generator price is a complicated function dependent on many parameters, the emphasis is mainly put on reduction of the weight of active materials, such as copper, laminated steel, permanent magnets, and electrical insulation.

  7. 5. Modelling and design approaches of magnetostrictive actuators

    Author : Mattias Oscarsson; Göran Engdahl; Tord Cedell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetostriction; Terfenol; Coil optimisation; Leakage flux; Modelling tools; Eddy currents; Magnetostriktion; Electrical engineering; Elektroteknik;

    Abstract : A magnetostrictive material elongates when it is subjected to a magnetic field. This effect can then be used to design powerful actuators. READ MORE
