Abstract
The utility model discloses a kind of novel actuator position feedback device, it is characterized in that: include housing, perform axle, execution axle magnet and Hall element circuit board, described execution axle magnet is arranged on execution axle, described Hall element circuit board is arranged on housing by screw, is provided with gap between Hall element circuit board and execution axle magnet.This utility model advantage compared with prior art is: this utility model is performing axle installation execution axle magnet, utilizes the rotation performing axle to drive execution axle magnet rotation；Hall element circuit board is fixed on directly over execution axle magnet, when performing axle and rotating, changes Hall element and perform axle operating fields, thus change feedback voltage, reach to substitute the purpose of slide potentiometer；Perform the Hall element circuit board that axle magnet is not directly contacted with, thus the vibrations avoiding execution axle cause the impaired problem of carbon film.
Description
Technical field
This utility model relates to feedback device, particularly relates to a kind of novel actuator position feedback device.
Background technology
Existing executor is air duct throttle opening self-control implementation device, and slide potentiometer is arranged on execution axle, air door position
The feedback put is to use to perform axle and drive slide plate to slide on fixed carbon resister, change resistance thus to change the mode of feedback voltage anti-
Feedback performs the position of axle, performs axle vibrations big, and slide plate easily causes carbon film to damage in fixed carbon resister vibrations, thus error of transmission,
Causing trouble.
Summary of the invention
This utility model is to solve above-mentioned deficiency, it is provided that a kind of novel actuator position feedback device.
Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of novel actuator position feedback
Device, it is characterised in that: including housing, perform axle, execution axle magnet and Hall element circuit board, described execution axle magnet is installed
Performing on axle, described Hall element circuit board is arranged on housing by screw, Hall element circuit board and execution axle magnet
Between be provided with gap.
This utility model advantage compared with prior art is: this utility model is performing axle installation execution axle magnet, profit
Drive with the rotation performing axle and perform the rotation of axle magnet；Hall element circuit board is fixed on directly over execution axle magnet, when holding
When row axle rotates, change Hall element and perform axle operating fields, thus change feedback voltage, reach to substitute the mesh of slide potentiometer
's；Perform the Hall element circuit board that axle magnet is not directly contacted with, thus the vibrations avoiding execution axle cause carbon film damaged
Problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As it is shown in figure 1, a kind of novel actuator position feedback device, it is characterised in that: include housing 1, perform axle 2,
Performing axle magnet 3 and Hall element circuit board 4, described execution axle magnet 3 is arranged on execution axle 2, described Hall element circuit
Plate 4 is arranged on housing 1 by screw 5, is provided with gap 6 between Hall element circuit board 4 and execution axle magnet 3.
Perform axle magnet 3 performing axle installation, utilize the rotation performing axle 2 to drive execution axle magnet 3 to rotate；By Hall unit
Part circuit board 4 is fixed on directly over execution axle magnet 3, when performing axle 2 and rotating, changes Hall element and performs axle 4 operating fields,
Thus change feedback voltage, reach to substitute the purpose of slide potentiometer；Perform the Hall element circuit that axle magnet 3 is not directly contacted with
Plate 4, thus the vibrations avoiding execution axle 2 cause the impaired problem of carbon film.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize equivalent structure or equivalence flow process conversion that this utility model description and accompanying drawing content made, or be directly or indirectly used in
Other relevant technical fields, are the most in like manner included in scope of patent protection of the present utility model.
