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

Abstract

The invention discloses a one-dimensional high-speed heavy-load limited rotation actuator which comprises a rotating shaft, two groups of coils, two groups of magnet assemblies and a shell, wherein the two groups of coils are symmetrically fixed to two sides of the rotating shaft, and each group of coils comprises n coils which are axially distributed along the rotating shaft; each group of magnet assemblies comprises n+2 layers of magnetizers and n+1 layers of permanent magnets which are longitudinally arranged in a staggered manner; each group of coils corresponds to one group of magnet assemblies, and the n coils are respectively and correspondingly sleeved on the magnetizers from the second layer to the (n+1) th layer, so that the upper part and the lower part of each coil are respectively provided with a layer of permanent magnet; when current flows through the two groups of coils, the magnet assembly generates a bias magnetic field to drive the two groups of coil assemblies to drive the rotating shaft to rotate around the axis of the rotating shaft. By adopting a multi-layer structure, the magnet is effectively utilized, the size and the weight are small, the torque is large, and the requirement for bearing large loads is met.

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...
