Design and Testing of Glass-Fiber Reinforced Plastic Components for the Oil-Cooling Air-Core Stator of a High Temperature Superconducting Motor

A Glass-fiber Reinforced Plastic (GFRP) components for the oil-cooling air-core stator of a High Temperature Superconducting (HTS) motor was designed and tested, and the process is summarized as follows. Firstly, the Computational Fluid Dynamics analysis of the stator was analyzed, the temperature and oil pressure of the GFRP components were chosen to be 50 °C and 0.1 MPa. Secondly, the structure of the components was analyzed by the finite element method. The results showed that the stresses of GFRP components in all directions are lower and without buckling at rated oil pressure. Finally, the full-scale GFRP components were designed and manufactured, and a full-scale simplified test platform was also developed to verify the strength of the components. The test results show that the strength, stiffness, and sealing performance of the GFRP components all satisfies the design requirements of the HTS motor.
