Abstract
AC servo motor.The bent blade mechanism of prior art is to make rotary motion be converted to movement in a curve by mechanical driving devices such as servomotor, reductor, worm screws, and this model attitude angle control system cannot avoid the machine error that the mechanical transmission mechanism such as reductor, worm screw brings.The inventive method includes: arcuate stator (2), has arc-shaped movement mechanism (3) in described arcuate stator, and arc rotor (1) is installed at described arc-shaped movement mechanism two ends；Also fixedly mounting arc encoder (4) on described arcuate stator, described arc encoder is connected with described arc rotor；Wherein, described arc-shaped movement mechanism is installed on support (5).The present invention is used for AC servo motor.
Description
Technical field:
The present invention relates to a kind of AC servo motor.
Background technology:
In wind tunnel test now, model attitude angle mechanism uses bent blade mechanism to realize movement in a curve mostly.The bent blade mechanism of prior art is to make rotary motion be converted to movement in a curve by mechanical driving devices such as servomotor, reductor, worm screws, and this model attitude angle control system cannot avoid the machine error that the mechanical transmission mechanism such as reductor, worm screw brings.The transmission of machine error make motor side position control cannot true translation in controlled device, it is impossible to meet the demand that high-precision attack angle controls.
The size of machine error directly determines bent blade mechanism kinematic error.With internal diameter it is
750mm
Tulwar supporting mechanism as a example by, the equipment such as decelerator, worm screw the tulwar arc of travel error brought is
1mm
, then the angle of attack of center of circle model will have
4.58
' machine error, it is difficult to meet all kinds of test position control requirement for model attitude angle.
For this type of situation, applicant designs a kind of DC servo motor, the accurate demand for control of movement in a curve component locations of the similar bent blade mechanism of reply.
Summary of the invention:
It is an object of the invention to provide a kind of AC servo motor.
Above-mentioned purpose is realized by following technical scheme:
A kind of AC servo motor, its composition includes: two arcuate stator
, there is in described arcuate stator arc-shaped movement mechanism, arc rotor is installed at described arc-shaped movement mechanism two ends；Also fixedly mounting arc encoder on described arcuate stator, described arc encoder is connected with described arc rotor；Wherein, described arc-shaped movement mechanism is installed on support.
Described AC servo motor, described arc rotor also has arc support, installs one group and be dielectrically separated from plate in described arc support, and described being dielectrically separated between plate has rotor copper cage；Wherein, between described arc support and rotor copper cage, also there is insulating coating.
Described AC servo motor, described rotor copper cage also has one group of copper bar being perpendicular to arc support, the center of circle of the described arc support described in the sensing of copper bar.
Described AC servo motor, described arcuate stator also has arc
U
Type port support, described arc
U
The medial wall of type port support has one group of stator slot, is wound around stator winding in described stator slot.
Described AC servo motor, described stator slot and stator winding are perpendicular to the edge camber line of described arc-shaped movement mechanism, and the center of circle of the arc-shaped movement mechanism described in sensing.
Described AC servo motor, described arc rotor is positioned at two described stator slots, and described arc rotor has with stator slot
1mm
Gap.
Beneficial effect:
The present invention by movement in a curve mechanism directly as rotor, the arc rotor making its two ends install moves in arcuate stator, and using hard-wired arc encoder on arcuate stator that arc-shaped movement mechanism is carried out absolute position detection, it is achieved high precision position controls and rotating speed controls.The frame for movement such as decelerator, worm screw is saved in the design of the present invention, it is to avoid error that mechanical transmission mechanism brings and the problem of noise.This simple in construction, control accuracy are high, the device of position detection has the advantage that measurement is direct, noise is little, error is little.
