Finite Element Modeling Method and Modal Analysis of a High Temperature Superconducting Motor

The development of high-temperature superconducting wire and cooling technology makes it possible to apply superconducting technology to motors. In actual use, the vibration problem of the high-temperature superconducting motor becomes the key. Structural modal analysis is the basis of structural vibration analysis. This article will take a high-temperature superconducting motor as the research object, and perform equivalent mass modeling of the complex stator coil ends and symmetrical cooling pipelines to simplify the whole Machine finite element model. Through the reasonable simplification of the finite element model, the modal simulation of the whole motor is completed, and then the prototype test is completed to verify the rationality of the simulation results.
