  1. 1. Kilowatt Three-phase Rotary Transformer Design for Permanent Magnet DC Motor with On-rotor Drive System

    Master-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

    Författare :Ye Xu; [2016]
    Nyckelord :contactless energy transfer; transformer power loss; iron loss; iron loss model; rotary transformer; three-phase transformer; finite element method; COMSOL Multiphysics; electrical steel; electrical steel manufacturing process;

    Sammanfattning : The aim of this thesis is to design a kilowatt three-phase step-down rotary transformer for a permanent magnet DC motor. The permanent magnet DC motor has an on-rotor drive system, and therefore requiring a power supply that can transfer power to its drive unit without mechanical contact. LÄS MER

    Sammanfattning : This thesis, which has been carried out at the department of research and development at Cobham Antenna Systems, comprises the development of a fluid rotary joint (FRJ) prototype and shall provide a thorough insight in relevant design aspects. Based on input parameters and objectives derived from an actual Cobham project, the possibility of manufacturing a fluid rotary joint in-house has been investigated. LÄS MER
