Description
Technical field
The utility model is related to a kind of model plane more particularly to a kind of model plane rudder accuracy-control systems.
Background technology
Currently, permanent magnet synchronous motor（PMSM）Rudder for controlling model plane needs during controlling model plane rudder
It is to be understood that accurate rotor-position, general use installs photoelectric encoder on the stator of permanent magnet synchronous motor, or rotation becomes
The positions such as depressor, magnetic coder harvester, however in some specific environments, it needs designing permanent-magnet synchronous motor very
Small, installing rheme at this time and setting the space of harvester does not allow；In addition this station acquisition device is installed to permanent-magnet synchronous
On motor, there is also the lower defects of acquisition precision.
Utility model content
The utility model provides one kind and is easily installed, does not increase motor body to solve shortcoming in the prior art
Product, the model plane rudder accuracy-control system that rudder turned position can be accurately controlled.
In order to solve the above technical problems, the utility model adopts the following technical solution：A kind of model plane rudder accurately controls
System, including micromotor, controller, multiturn potentiometer and speed changer, the main shaft of micromotor and the power of speed changer input
Axis is sequentially connected, and the power output shaft of speed changer is connect with rudder, and the mechanical input shaft of multiturn potentiometer passes through machine driving
Mechanism and the pto shaft drive of speed changer connect, and the signal output end of multiturn potentiometer passes through position feed back signal line and control
Device connection processed, controller are connect by driving power control line with micromotor.
Multiturn potentiometer is arranged on speed changer, and mechanical transmission mechanism includes driving gear and driven gear, driving gear
It is coaxial on the power output shaft of speed changer, the coaxial mechanical input shaft mounted on multiturn potentiometer of driven gear
On, driving gear is engaged with driven gear.
Using above-mentioned technical proposal, micromotor drives rudder to rotate by speed changer, the power output shaft of speed changer
On driving gear drive driven gear rotation, driven gear to pass through the rotation of the mechanical input shaft of multiturn potentiometer, multi-turn current potential
Device measures voltage value in real time, and the collected voltage value of multiturn potentiometer is an analog quantity, and signal is passed to controller, control
Device is counted as digital quantity by the analog-digital conversion function solution of DSP, each exact position of corresponding direction rudder, and then controller is by future time
The signal of position of rudder rotation is transferred to micromotor by driving power control line, to the main axis of micromotor into
Row control, the main axis of micromotor drive rudder to rotate again by speed changer.
In conclusion the utility model it is novel in design, it is simple in structure, be easily installed and implement, is highly reliable, control essence
Really, the volume of micromotor can be fully reduced, it is widely applicable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, a kind of model plane rudder accuracy-control system of the utility model, including micromotor 1, controller
2, multiturn potentiometer 3 and speed changer 4, the main shaft of micromotor 1 are sequentially connected with the power input shaft 5 of speed changer 4, speed changer 4
Power output shaft 6 connect with rudder 7, the mechanical input shaft of multiturn potentiometer 3 passes through mechanical transmission mechanism and speed changer 4
Power output shaft 6 is sequentially connected, and the signal output end of multiturn potentiometer 3 is connect by position feed back signal line 8 with controller 2,
Controller 2 is connect by driving power control line 9 with micromotor 1.
Multiturn potentiometer 3 is arranged on speed changer 4, and mechanical transmission mechanism includes driving gear 10 and driven gear 11, master
Moving gear 10 is coaxial on the power output shaft 6 of speed changer 4, and driven gear 11 is coaxial to be mounted on multiturn potentiometer 3
Mechanical input shaft on, driving gear 10 is engaged with driven gear 11.
The operation principle and process of the utility model is：Micromotor 1 drives rudder 7 to rotate by speed changer 4, speed change
Driving gear 10 on the power output shaft 6 of device 4 drives driven gear 11 to rotate, and driven gear 11 passes through multiturn potentiometer 3
Mechanical input shaft rotates, and multiturn potentiometer 3 measures voltage value in real time, and 3 collected voltage value of multiturn potentiometer is a simulation
Signal is passed to controller 2 by amount, and controller 2 is counted as digital quantity by the analog-digital conversion function solution of DSP, and corresponding direction rudder 7 is each
Exact position, then controller 2 signal for the position that future time rudder 7 rotates is transmitted by driving power control line 9
To micromotor 1, the main axis of micromotor 1 is controlled, the main axis of micromotor 1, passes through the band again of speed changer 4
Dynamic rudder 7 rotates.
The present embodiment not makes any form of restriction the shape of the utility model, material, structure, direction etc., all
It is any simple modification, equivalent change and modification made by the above technical examples according to the technical essence of the present invention, belongs to
In the protection domain of technical solutions of the utility model.
