  1. 1. Blomfröodling : metoder och förutsättningar för produktion i Sverige

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Lovisa Ekström; [2023]
    Keywords : blomfröer; fröproduktion; fröodling; pollinering; fröskörd;

    Abstract : Samtidigt som miljö och hållbarhet diskuteras flitigt när det kommer till odling importeras den största delen fröer som odlas i Sverige. Detta gäller inte minst blomfröer. Genom en litteraturstudie beskrivs faktorer, metoder och odlingssystem som är av betydelse vid fröproduktion. READ MORE

  3. 2. Sensorless Control of Synchronous Reluctance Machines and Permanent Magnet Synchronous Machines for Pump Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Erik Lindberg; [2023]
    Keywords : Variable speed drives; Sensorless control; Luenberger observer; Synchronous reluctance machine; Permanent magnet synchronous machines; Vector control; Model reference adaptive system; Variabel hastighetsreglering; Sensorlös reglering; Luenberger observatör; Synkron reluktansmaskin; Permanentmagnetmaskin; Vektorreglering; Adaptiv modelreferensreglering;

    Abstract : Energy efficiency in electric machines is both environmentally and economically important. Water pumps with an integrated Variable Frequency Drive (VFD) and a Permanent Magnet Synchronous Machine (PMSM) have challenged the status quo of the Induction Machine (IM) for water pumps.

  4. 3. Rotor temperature estimation in Induction Motors with Supervised Machine Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Christopher Gauffin; [2023]
    Keywords : Induction motors; Supervised Machine learning; Power converters; Parameter estimation; Embedded systems; Induktionsmotorer; Övervakad maskininlärning; Strömkonverterare; Parameterestimering; Inbyggda system;

    Abstract : The electrification of the automotive industry and artificial intelligence are both growing rapidly and can be greatly beneficial for a more sustainable future when combined. Induction machines exhibit many complex relationships between physical and electromagnetic properties that must be calculated in order to produce the correct quantities of torque and speed commanded by the driver.

  5. 4. Heat-pipes in electric machines : Heat management in electric traction motors

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Anton Olofsson; [2022]
    Keywords : Heat-pipe; Heat pipe; FEM; LPM; Traction motors; Induction motor; Heat management;

    Abstract : The world is continually changing towards more energy efficient alternatives and less pollution. For the traction market, electric powertrains have become the go-to method, superior to both steam and diesel-electric hybrid systems. READ MORE

  6. 5. Investigation of Variable Speed Technology when Converting Hydropower Kaplan Turbines into Fixed Propeller Turbines

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Johannes Ansved; [2022]
    Keywords : hydropower; variable speed; kaplan; turbines; model; simulation;

    Abstract : With an evolving energy system, an increased flexibility is necessary, placing additional demand on hydropower plants. New technology, in particular full size frequency converters (FSFC) and doubly fed induction machines (DFIM), allows hydropower turbines to run at different speeds than originally designed, thus making the turbine more flexible.
