  1. 1. 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.

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

    Author : Simon Lundberg; [2022]
    Keywords : High-frequency signal injection; Permanent Magnet Synchronous Motor; sensorless speed control; Synchronous Reluctance Machine; square-Wave injection; Fyrkantsvågsinjektering; högfrekvent signalinjektering; Permanentmagnetsmotor; sensorlös hastighetskontroll; synkron reluktansmotor;

    Abstract : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. READ MORE

  4. 3. Design, Analysis and Implementation of a Drive System for Delsbo Electric Light Rail Vehicle

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

    Author : Daniel Marklund; Maria Lindh; [2022]
    Keywords : pulse and glide; rail vehicle; drive system; Delsbo Electric;

    Abstract : The aim of this project is to design and implement a drive system and a driving strategy for a lightweight, battery-driven rail vehicle partaking in the Delsbo Electric student competition. The goal of the competition is to create a vehicle which consumes as little energy as possible. READ MORE

  5. 4. Real-time implementation of PMSM software model on external hardware

    University essay from KTH/Elkraftteknik

    Author : Alexander Sjöberg; [2017]
    Keywords : Model based software development; permanent magnet synchronous motor modelling; real-time software model; Modellbasserad mjukvaruutveckling; modellering av permanentmagnetiserade synkronmotorer; realtidsmodellering;

    Abstract : When developing three phase motor drives, the best way to validate the desiredfunctionality is to connect the inverter to an actual electrical motor. However, when developingfunctions which are not directly involved in controlling the motor, it could bemore efficient to use a real-time software model of the motor. READ MORE

  6. 5. Magnet Losses in Inverter-fed High-speed PM Machines

    University essay from KTH/Elektrisk energiomvandling
