Abstract
The utility model discloses a detection apparatus for rotor speed and direction, including rotor and printed circuit board, the rotor include pivot and magnetic ring, and the pivot pass the magnetic ring and with magnetic ring fixed connection, its innovation point lies in: printed circuit board's same surface is being provided with hall element near magnetic ring department, hall element is connected with the printed circuit board electricity. The utility model discloses magnetic ring N, S magnetic field signal extremely can be stably detected, the reliability of controller detected signal is improved.
Description
Technical field
The utility model relates to the device in a kind of detection rotor rotating speed and direction, belongs to technical field of motors.
Background technology
Hall element is critical function parts in monitoring rotor speed and direction, Hall element on the Hall circuit board of general motor really cannot accomplish that annular distributes around magnet ring, when motor oscillating is excessive, wiring board cannot true vertical in rotating shaft, thus cause Hall element and magnet ring distance of reaction to change, cause signal to export bad, there is reliability hidden danger.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides the checkout gear in a kind of rotor speed and direction, and it can the field signal of stable detection magnet ring N, S pole, improves the reliability of controller detection signal.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the checkout gear in a kind of rotor speed and direction, comprise rotor and printed substrate, described rotor comprises rotating shaft and magnet ring, and rotating shaft is passed magnet ring and is fixedly connected with magnet ring, its innovative point is: the same surface of described printed substrate is being provided with Hall element near magnet ring place, and described Hall element is electrically connected with printed substrate.
The plane at described printed substrate place and the center line of rotating shaft perpendicular.
Described Hall element is at least provided with three, and is distributed in ringwise around rotating shaft.
The upper and lower surface of described printed substrate all scribbles glue, causes the hidden danger that electronic devices and components loosen to avoid motor to shake.
After have employed technique scheme, the utility model has following beneficial effect:
1) rotor turns forms magnetic field, detects N, S polarity of magnet ring and magnetic field intensity thus the rotating speed of detection rotor and direction by connecting Hall element on a printed-wiring board;
2) the above and below gluing of printed substrate, is fixed on motor securely, effectively can eliminate the Hall element caused because motor oscillating is excessive and the hidden danger that magnet ring distance of reaction changes and electronic devices and components easily loosen;
3) multiple Hall element can provide multiple hall signal to export, and when wherein a road or two-way hall signal export bad, the output of other hall signals is unaffected;
4) Hall element is distributed in the field signal of N, S pole that effectively can accept magnet ring around rotating shaft ringwise, and hall signal is fed back to automotive control system, improves the reliability that controller detects motor speed and direction signal.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment one of the present utility model.
Embodiment
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, the checkout gear in a kind of rotor speed and direction, comprise rotor 1 and printed substrate 2, described rotor 1 comprises rotating shaft 3 and magnet ring 4, and rotating shaft 3 is passed magnet ring 4 and is fixedly connected with magnet ring 4, it is characterized in that: the same surface of described printed substrate 2 is being provided with Hall element 5 near magnet ring 4 place, and described Hall element 5 is electrically connected with printed substrate 4.
The plane at described printed substrate 5 place and the center line of rotating shaft 1 perpendicular.More be conducive to the accuracy of detection signal and result.
Described Hall element 3 is at least provided with three, and is distributed in rotating shaft 1 ringwise around.The Hall element that the utility model adopts is 3, can be 4 or more certainly.
The upper and lower surface of described printed substrate 4 all scribbles glue, causes the hidden danger that electronic devices and components loosen to avoid motor to shake.
Rotor turns forms magnetic field, detects N, S polarity of magnet ring 4 and magnetic field intensity thus the rotating speed of detection rotor and direction by the Hall element 5 be connected on printed substrate 2; Printed substrate 2 is fixed on motor securely by gluing, effectively can eliminate the hidden danger that distance of reaction changes and electronic devices and components easily loosen of the Hall element 5 and magnet ring 4 caused because motor oscillating is excessive; Multiple Hall element 3 can provide multiple hall signal to export, and when wherein a road or two-way hall signal export bad, the output of other hall signals is unaffected; The surrounding that Hall element 5 is distributed in rotating shaft 1 ringwise effectively can accept the field signal of N, S pole of magnet ring 4, and hall signal is fed back to automotive control system, improves the reliability that controller detects motor speed and direction signal.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
