Problems solved by technology

The existing rotary drive device is mainly a rotary motor. This kind of mechanism itself has a relatively complicated structure, and often needs to be combined with other transmission components to control the motion. The efficiency is low and the response speed is slow.
In particular, in the case of limited volume, it is often unable to provide a large driving torque, and cannot meet the needs of modern industry for micro precision drive control and positioning
[0003] In the existing rotating shaft, the stator of the rotating shaft and the mover of the rotating shaft can only be arranged non-coaxially, resulting in a large radial dimension of the shaft, and the permanent magnet will demagnetize at high temperature, causing the driving effect to decrease due to high temperature and cannot work
[0004] At present, there is no description or report of the similar technology of the present invention, and no similar data at home and abroad have been collected yet.

[0087] figure 1 It is a structural schematic diagram of the rotary driving device that can be implemented in a relatively high temperature environment in the first embodiment of the present invention. The first embodiment is a preferred example of the above-mentioned basic embodiment. In this embodiment, one side of the rotating shaft stator is provided with a rotating shaft mover; the number of the rotating shaft stator is one. The reset mechanism drives the opposite end surfaces of the mover magnet and the stator magnet to rotate to a dislocation position. The reset mechanism can be a hinge spring or a torsion spring. Such as figure 1 as shown, figure 1 The dotted line in the mark indicates the fixed position link of the rotating shaft stator, which can be fixed by interference fit or fastened connection by fasteners such as screws.

Abstract

The invention provides a rotation driving device capable of being implemented in a relatively high temperature environment. A rotation shaft stator and a rotation shaft rotor are coaxially or non-coaxially arranged, and opposite end surfaces of a stator magnet and a rotor magnet can rotate relative to each other between a dislocation position and a non-dislocation position. In the rotation driving device, a stator and a rotor can be arranged in the same axial direction, so that the radial size of a shaft is reduced; a coil magnet yoke and a rotor magnetic attraction body can be made of magnetic conduction material bodies so as to be different from a permanent magnet and can be used in a relatively high temperature environment; a rotor magnet yoke is formed by a plurality of small units which are embedded into a rotor structural body groove, the size of the yoke in a rotational direction can be conveniently adjusted according to a single cylinder and combination thereof; a plurality of stator and rotor pairs are combined in a series form, so that the rotation output torque can be multiplied; and when a coil in a stator comprises two coils, rotation in a reciprocating way can be achieved by making the two coils alternately energized and acting on an adjacent rotor.

Description

technical field [0001] The present invention relates to drive technology, in particular, to a rotary drive device that can be implemented in a relatively high temperature environment. Background technique [0002] The precision controllable rotation drive device is mainly used in the adjustment of the spatial position of the mechanism, the tracking of the target object, and the active control of the vibration of the flexible structure. By controlling the rotation of the sub-components, the adjustment of the spatial position of the mechanism is realized, and then the tracking of the target object and the active control of the vibration of the flexible structure are realized. The existing rotary driving device is mainly a rotary motor, which has a relatively complex structure and often needs to be combined with other transmission components to control the motion, with low efficiency and slow response speed. In particular, in the case of limited volume, it is often unable to p...
