Abstract: In this paper, the electric-magnet characteristics of the pressure vessel in CRDM drive motor is studied by the Finite Element Method. The influence law on the he electric-magnet characteristic is studied through analyzing the output torque of drive motor in different pressure vessel material or in different structure size. The result shows that the electric-magnet characteristic of the pressure vessel in CRDM drive motor can be acquired accurately by the Finite Element Method, which has advantages on reducing design time and physical prototype experiment cost.
