Abstract

The invention relates to a parallel double-structure voice coil motor which comprises a stator magnetic steel assembly and a rotor coil assembly. The stator magnetic steel assembly is fixed on a fixed part, the rotor coil assembly is fixed on a movable part, and an output force parallel to a central shaft can be generated by powering up a coil in the rotor coil assembly; the stator magnetic steel assembly comprises a stator outer sleeve, a stator inner assembly inner magnetic steel part, a stator inner assembly outer magnetic steel part, a stator outer assembly inner magnetic steel part and a stator outer assembly outer magnetic steel part; and the stator inner assembly inner magnetic steel part, the stator inner assembly outer magnetic steel part, the stator outer assembly inner magnetic steel part and the stator outer assembly outer magnetic steel part are all installed in the stator outer sleeve and fixedly connected with the stator outer sleeve. According to the invention, the environmental test requirements of a space mechanism on the ground without gravity and external disturbance power can be met.

Description

technical field [0001] The invention relates to a parallel double-structure voice coil motor, which belongs to the technical field of spacecraft ground tests. Background technique [0002] With the development of aerospace technology, the requirements for the performance of spacecraft mechanism products in orbit are getting higher and higher. The current research on ultra-wide and high-resolution optical satellites for large-aperture cameras vertically scanning and stitching imaging along the track uses suspension joints to provide high-precision support and precise drive rotation for larger-mass cameras, in order to achieve a uniform speed And stable scanning to obtain high definition of scanned images for each frame. The high-precision and stable rotation of the suspension joint is the guarantee to ensure the stable work of the camera load. [0003] The satellite is in a gravity-free state on the orbit, and the test and experiment state on the ground is a gravity environ...
