  1. 1. CURRENT OVERSAMPLING ANALYSIS FOR ADVANCED CONTROL OF ELECTRIC AC DRIVES

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marco Giuliato; [2019]
    Nyckelord :;

    Sammanfattning : The main purpose of this thesis is to develop a sensorless control for a synchronous reluctance motor by using the slope measurement of the current ripple introduced by the Space Vector Modulation.The position estimation is performed at each Space Vector Pulse Width Modulation period and it relies on the estimation of current derivatives.

  2. 2. Utvärdering av roterande borstlösfrekvensomformare tillspårledningar

    M1-uppsats, KTH/Hälsoinformatik och logistik; KTH/Hälsoinformatik och logistik

    Författare :Leith Aldahan; Ivan Kudoori; [2019]
    Nyckelord :Frequency converter; induction motor; track circuit; asynchronous motor; railway signaling; reluctance motor; RAMS; Frekvensomformare; asynkronmotor; spårledning; asynkronmaskin; signalsystem; reluktansmotor; RAMS;

    Sammanfattning : Spårledningar används inom tunnelbanan för att visa tågets position samt bestämma tågets hastighet genom att bryta spänningsamplituden i signalen vid olika frekvenser. Frekvensen till spårledningen fås från en roterande frekvensomformare. I dagens anläggning används roterande frekvensomformare med borstar. LÄS MER

  3. 3. Design and comparison of PMaSynRM versus PMSM for pumping applications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Viktor Briggner; [2018]
    Nyckelord :Demagnetization; economic evaluation; permanent magnet assistance; synchronous reluctance machine; Avmagnetisering; ekonomisk utv¨ardering; permanentmagnetassistans; synkron reuktansmaskin;

    Sammanfattning : This master thesis aimed to design a permanent magnet assisted synchronous reluctancemachine (PMaSynRM) rotor for pump applications which were to be implemented inan existing Induction Machine stator. The machine were to be compared with a similarpermanent magnet synchronous machine (PMSM) with similar torque production in termsof cost and performance. LÄS MER

    Sammanfattning : With the increasing environmental impact from the automotive industry, electric vehicles become more and more popular. This combined with the great breakthroughs in fast electronics the switched reluctance motor (SRM) has again gained popularity in recent years. LÄS MER

  5. 5. An integrated brake disc and electric drive for vehicle propulsion : A FEASIBILITY STUDY

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Johan Linder; [2016]
    Nyckelord :Axial flux; brake disc; core less rotor; in wheel motor; hub motor; quarter car model; segmented rotor; switch reluctance machine; single teeth winding.; Axialflödes; bromsskiva; enkeltandad lindning; hjulmotor; hub motor kvartfordonsmodell; rygglös rotor; segment rotor; variabel reluktansmaskin;

    Sammanfattning : In this thesis, the feasibility to integrate an brake disc and electric machine is investigated. In wheel motors (IWMs) have several advantages, such as saving space in the vehicle, individual and direct control at the wheels and the absence of a mechanical transmission. LÄS MER
