  1. 21. Online parameter estimation in electric motors

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Abizar Sadikot; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The permanent magnet synchronous machine (PMSM) can be used for a wide range of applications. In this case, the motor that is examined is inspired of Husqvarna's handheld electrical tools where the motor is part of its electrical chainsaw. The idea is to investigate and simulate different algorithms for online parameter estimation for the PMSM. LÄS MER

    Sammanfattning : In the aviation industry, safety and robustness are the number one priorities, which is why they use well-tested systems such as hydraulic actuators. However, drawbacks such as high weight and maintenance have pushed the industry toward newer, electrical, actuators that are more efficient and lighter. LÄS MER

  4. 23. Design of an electric motor (PMSM) & manufacturing lab

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Lama Awawda; [2021]
    Nyckelord :Permanent magnet synchronous machine; PMSM; Finite element analysis FEA ; FEMM; Hairpin winding; Motor assembly; Prototype;

    Sammanfattning : The thesis presents deals with the design, analysis, test and control of permanent magnetsynchronous motor(PMSM). An analytical model was carried out based on the d-q frame and the equivalent circuit of PMSM, theanalytical model gives an approximation value of the machine parameters and is carried out byequations from the listed references.
