Abstract
The LIP has developed space cryogenics since 2000, and has taken great progress in Stirling cryocooler. For domestic and potential application in future in space mission, a large cooling capacity Stirling cryocooler with a heat lift of 10W at 260W electric power input has been developed. In order to meet the rigor demand for large impulse, high efficient and tight compactness, the moving coil motor and moving magnet motor has been evaluated through analysis. The moving magnet motor performs high efficient and better compactness. A moving magnet motor is new to LIP. The magnet circuit for elements tests was evaluated by a basic equation and computed by multi-purpose FEM software. The results from the element tests and calculation data were used for improving design. This paper describes the development the motor design and analysis results.
