The aim of the reduction method is to integrate the reduced model in a multi-physical electric machine optimization procedure and use the obtained model in real-time monitoring of machine critical parts. In this paper, an electric machine thermal model reduction method is proposed. Using the lumped parameter thermal network (LPTN) method, a thermal model is developed in order to represent the thermal...
This paper presents a step-by-step procedure to study the impact of each thermal phenomenon occurring in electric machines on their internal temperature distribution. First, the Monte-Carlo method is chosen as a global sensitivity analysis technique. This method is applied on a thermal network of a prototype consisting of a permanent magnet based integrated starter-generator machine (ISG). Accordingly,...
Design and performance of mechatronic systems depends on many factors and subsystems like gears, hydraulic components and electric motors. These latter are considered as a principle device in electromechanical power conversion, thus their design becomes of a prime importance. This paper aims to build electric motor models along with its control strategy and power electronics component in order to...
This paper presents a new methodology for identifying, by means of inverse methods, the convective heat exchange coefficients between an electric machine and ambient air. The inverse method that we use involves minimizing the residual between the machine's internal losses and the total amount of heat extracted to ambient air in a thermal steady-state condition. First, we start by establishing the...
