Concerning the structural complexity of large-scale turbogenerator stator, this research aims at establishing the windings model of the large-scale turbogenerator stator ends by using ANSYS, including the ends of upper and lower condutor bars, spacer blocks between adjacent condutor bars, and inter-layer rings between the upper and lower condutor bars. Moreover, the modal analysis of the stator end windings was performed with the help of ANSYS, and the parameterized finite element analysis was further conducted on the space blocks that may affect the overall structural mode and natural frequency of the ends, and the influence trend of the space blocks on the natural frequency of the elliptical mode was obtained. It provides a reference for the design of the generator end structure and its improvement, and also provides a basis for the subsequent research on the electromagnetic vibration of the end windings and the stator windings.
