چکیده
|
Usually,electrical machines have a metallic cylinder made up of a compacted stack of thin metal plates (referred as laminated core) assembled with an interference fit on the shaft. the laminated structure is required to improve the electrical performance of the machine and,besides adding inertia,also enhances the stiffness of the system. inadequate characterization of this element may lead to errors when assessing the dynamic behavior of the rotor. the aim of this work was therefore to evaluate three beam models used to represent the laminated core of rotating electrical machines. the following finite element beam models are analyzed: (i) an equivalent diameter model
