Problems solved by technology
This results in acceleration and size that cannot meet performance requirements.
At the same time, the current brake design efficiency is relatively low
In this way, the existing solution is inefficient and heavy, and it is impossible to drive the fast mirror to move at a higher acceleration

A one-dimensional high-speed large-load limited-rotation actuator of the present invention includes a rotary shaft, two sets of coils, two sets of magnet assemblies and a housing; two sets of coils are symmetrically fixed to both sides of the rotary shaft, and each set of coils includes n coils , axially distributed along the rotary axis; each group of magnet assemblies includes n+2 layers of magnetizers and n+1 layers of permanent magnets arranged longitudinally and staggered; each group of coils corresponds to a group of magnet assemblies, and n coils are respectively sleeved on the second To the n+1th layer of magnetizer, so that there is a layer of permanent magnets on the upper and lower parts of each coil; current flows through the two sets of coils, and the magnet assembly generates a bias magnetic field, driving the two sets of coil assemblies to drive the rotation axis around the rotation axis Axis rotation. By adopting a multi-layer structure and effectively using magnets, the volume and weight are small and the torque is large, so as to meet the requirements of undertaking large loads.
Description
technical field [0001] The invention relates to the technical field of photoelectric scanning and tracking, in particular to a one-dimensional high-speed and large-load limited-rotation actuator. Background technique [0002] The fast reflector is a component that works between the light source or receiver and the target to adjust and stabilize the visual axis of the optical system or the beam pointing. By using a voice coil motor to precisely control the deflection direction of the reflector, the beam deflection angle can be precisely controlled. Due to It has the advantages of compact structure, fast response speed, high working bandwidth, and high pointing accuracy. It is widely used in astronomical telescopes, adaptive optics, image motion compensation, free space optical communication, and precision tracking. It has become a stable beam and A key device for correcting the direction of beam propagation. [0003] An important indicator of the fast mirror is the operating...
