    Nyckelord :Asymmetrical six-phase induction machine; indirect rotor field oriented control; machine rewinding; multiphase electrical machines; PCB design; speed control; the star of the slot .; Asymmetrisk sexfasig asynkronmaskin; flerfasiga elektriska maskiner; hastighetsreglering; indirekt rotorfälts orienterad reglering; kretskorts design; maskinomlindning; the star of the slot .;

    Sammanfattning : Electrical machines with more than three phases are usually called multiphase electrical machines and they can have several advantages compared to conventional three-phase electrical machines such as a lower content of space-harmonics, lower torque ripple and better fault tolerance. This degree project involves rewinding of a three-phase induction machine into an asymmetrical six-phase machine. LÄS MER

  3. 2. Wireless Body Area Network for Patient Monitoring in Hospitals

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Divya Vinod Kalkotwar; [2016]
    Nyckelord :IEEE 802.15.4; wireless body area network; beacon mode; CSMA CA; NFC; patient monitoring.;

    Sammanfattning : The master thesis is a prototyping project of a wireless body area network (WBANs) for patient monitoring in hospitals. The goal of this project was to study various technologies suitable for wireless body area networks, complete a requirement analysis, design a WBAN suitable to achieve the requirements and to test and evaluate the system against the requirements.

  4. 3. Improving Aerodynamic Performance of a Truck: a Numerical Based Analysis

    M1-uppsats, KTH/Mekanik

    Författare :Johan Malmberg; [2015]
    Nyckelord :;

    Sammanfattning : With a change in EU-legislation regarding the dimensions of heavy trucks [1] coming up, specifically allowing aerodynamic devices fitted to the back of trailers, the transportation industry is set to largely decrease its environmental impact in the near future. These aerodynamic devices have been researched for quite some time [2] but have not yet gained widespread market acceptance, partly because of the transportation industry’s complex owner structures and partly because of size regulations of the past.
