Description
Technical field
The utility model relates to a kind of electric machine structure more particularly to a kind of stabilizer motor connecting structures.
Background technique
Currently, the auxiliary stabilizer of the large size capture apparatus such as slr camera generallys use the biggish motor of power, in large size
In the stabilizer R&D process of the relatively large loads such as capture apparatus, stability is most important, and therefore, existing large size stabilizer adds
The thickness and iron core of shell, end cap in big electric machine structure, magnetic material length guarantee the stability of stabilizer.With three
Axis stabilizer is illustrated, and is connected separately with linking arm on the end cap at roll motor both ends, therefore, is led to the lever arm of force of motor shaft
Larger, under the action of the external force such as capture apparatus gravity, user's movement, the stability of motor shaft is poor；Due to two connections
The distance between arm is larger, therefore smaller (the installation photographic equipment of stabilizer in gold space of the installation photographic equipment of stabilizer
Gold space refer to the space that its corresponding electrical axis of stabilizer linking arm surrounds)；Again due to the sense of motor shaft one end
Answering magnet is to cover upper screw-internal thread fit by the external screw thread and induced magnet of motor shaft to fix, therefore motor shaft is in two bearings
Spacing on the basis of also to increase by the empty avoiding height of one section of externally threaded length and magnet and encoder, cause the thickness of motor compared with
It is thick；And under the stabilizer intensity requirement that large-scale capture apparatus uses, since linking arm is connect with end cap, it is therefore desirable to increase
The thickness of end cap causes the integral thickness of motor larger.
In the prior art, Chinese patent CN206164281U discloses a kind of motor, the holder with motor and has cloud
Two bearings of the unmanned plane of platform, the motor are limited by the limiting stand inside circlip and motor, the elasticity and axis of circlip
The diastema held causes motor shaft to move axially in the course of work of motor, influences the stability of motor；The electric machine structure
In motor shaft and the rotor one end of magnet steel carrier (have) by the threaded connection of fastener, this connection type is in motor
Thread error is increased in the rotation process of axis, influences the verticality of motor shaft, leads to the stability of motor, and is inconvenient to pacify
Dress；The electric machine structure carries out limit using the limiting stand inside circlip and motor and replaces motor to shorten the length of motor shaft
The structure of shaft end portion external screw thread limiting stand, but gasket, elastic component, fastener on the limiting stand and motor shaft inside its motor
Equal components are various, are not easy volume production, and production and the efficiency assembled are lower.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of stabilizer motor connecting structure, it is intended to solve existing stabilization
The gold space that device installs photographic equipment is smaller, is not available macro lens camera, large-scale photographic equipment；Motor shaft is longer, motor
Axis verticality is poor, and stability is poor；The production of motor, the problems such as packaging efficiency is lower.
The utility model adopts the following technical solutions to achieve above-mentioned purpose:
A kind of stabilizer motor connecting structure, including metal hollow motor shaft, iron core shell, be respectively fitted over metal hollow electricity
