Description
Technical field:
The present invention relates to a kind of DC 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.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.Assume that the tulwar arc of travel error brought by the equipment such as decelerator, worm screw 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 DC servo motor.
Above-mentioned purpose is realized by following technical scheme:
A kind of DC servo motor, its composition includes: two arcuate stator
Described arcuate stator is slidably installed arc-shaped movement mechanism, arc rotor is installed at described arc-shaped movement mechanism two ends, there is in described arc rotor one group of arc support, described arc support medial wall has rotor slot, there is in described rotor slot insulating coating, described rotor slot is wound around rotor windings；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 DC servo motor, described rotor slot is perpendicular to the center of circle of the arc support described in described arc support sensing.
Described DC servo motor, described arcuate stator also has arc
U
Type port support, described arc
U
The port of type port support and port bottom connect brush, described arc respectively
U
The medial wall of type port support has one group of stator slot, is wound around stator winding in described stator slot.
Described DC servo motor, described brush contacts connection with described rotor windings.
Described DC 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 DC servo motor, described arc rotor, between two described stator slots, has between described arc rotor and stator slot and is less than
3mm
Gap.
Beneficial effect:
The present invention installs arc rotor at the two ends of arc-shaped movement mechanism, and arc-shaped movement mechanism is slidably installed with arc rotor, utilize arc-shaped movement mechanism directly as rotor, and utilizing the encoder installed on arcuate stator to carry out absolute position detection, it is achieved high precision position controls and rotating speed controls.Present configuration eliminates the frame for movement such as decelerator, worm screw in raw DC servomotor, it is to avoid error that mechanical transmission mechanism brings and the problem of noise.Have that simple in construction, control accuracy be high, position detection directly, noise is little, error is little advantage.
