  1. 1. Modeling and Testing of Insulation Degradation due to Dynamic Thermal Loading of Electrical Machines

    University dissertation from Division of Industrial Electrical Engineering and Automation, Faculty of Engineering, Lund University

    Author : Zhe Huang; [2017-01-03]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal degradation; thermal cycle; dynamic temperature; thermal-mechanical; fatigue; electrical insulation system; accelerated testing; condition monitoring; electrical machine; electrified vehicles;

    Abstract : Electrical machines in electrified vehicles are subjected to dynamic loadings at different driving conditions, which results in dynamic temperatures. The aging of the Electrical Insulation System (EIS) in electrical machines is caused by these dynamic temperatures, namely high average temperatures and temperature cycles. READ MORE

  2. 2. Thermal Design of Electrical Machines - Investigation and Evaluation of Cooling Performances

    University dissertation from Division of Industrial Electrical Engineering and Automation, Faculty of Engineering, Lund University

    Author : Zhe Huang; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This Thesis focuses on thermal design of permanent magnet synchronous electrical machines (PMSM) used in hybrid vehicles (HEVs) or zero emission vehicles (ZEVs). Electrical machines in such applications are usually designed with high power density requirements but within limited spaces, which lead to high rate of heat generation but low rate of heat dissipation.
