【Abstract】 In view of the locking requirements of the optical devices on the satellite, after comparison of various schemes, a contactless locking motor structure was proposed, which has the characteristics of lightweight and high resolution. The finite element simulation software was combined with theory for modeling and magnetic field calculations. The prototype was developed and the experimental test was carried out. The experimental results show that the proposed locking scheme has certain engineering practical value.更多还原
