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.

Abstract

The present invention provides a rotary drive device capable of implementing rotation in a relatively high temperature environment, wherein the stator of the rotating shaft and the mover of the rotating shaft are coaxially or non-coaxially arranged; Relative rotation between non-displaced positions. In the present invention: the stator and the mover can be arranged in the same axial direction, which realizes the reduction of the radial dimension of the shaft; the coil yoke and the rotor magnetic attraction body can be magnetically conductive materials, which are different from permanent magnets and can be used at a higher The rotor yoke can be used at high temperature; the rotor yoke can be embedded in the groove of the rotor structure with multiple small units, so that the size adjustment of the yoke in the direction of rotation can be easily realized according to a single column and its combination; multiple stators The rotor pair is combined in series, which can double the rotational output torque; when the coil in the stator is composed of two coils, the reciprocating rotation can be realized by alternately energizing the two coils and acting on the adjacent mover .

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...
