Abstract
The utility model discloses a Hall measurement tool equipment for brushless motor circuit board. Three detecting contacts in the circuit board are provided. The circuit board provides a base in whose cavity is positioned with a fixed block. The fixed block is connected with the base through a fixed shaft installed passing through it. Three contacting needles in the fixed block are positioned. The bottom ends of the needles are connected with the circuit board via a wire. A motor is positioned on the bottom of the circuit board corresponding to the base. The output shaft of the motor is connected with a magnetic steel loop. The upper end of the steel loop rises above that of the contacting needles. For operation, the circuit board of the brushless motor shall be put on the fixed shaft so that the output terminal can touch the contacting needles on the fixed blocks. In this way, it can provide power for the motor and spin the magnetic loop. The spinning steel loop in this utility model will generate Hall effects. Then, through the testing contacts on the circuit board, the wave frame created can be seen from the oscilloscope, which offers a convenient determination of the assembly quality for the brushless motor circuit.
Description
Technical field
The utility model relates to a kind of Hall and detects frock, and the Hall that specifically relates to a kind of brushless electric machine circuit board detects frock.
Background technology
The brushless electric machine circuit board requires welding superior, after the assembling completion, need detect circuit structure, and detecting is to utilize the Hall effect principle mostly.But in the prior art, it is unreasonable that this class pick-up unit often exists structure, causes detection efficiency low, even testing result is unreliable etc. not enough.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical matters, provides a kind of Hall to detect frock.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of Hall detects frock, comprise a circuit board, circuit board is provided with and detects the contact, described circuit board is provided with base, be arranged with fixed block in the base, relative bottom side at circuit board with base is provided with motor; Side in described fixed block upper surface is provided with some contact pilotages, wears two stationary shaft in fixed block, and the lower end of stationary shaft is fixed on the base; Motor output shaft is provided with magnetic steel ring, and the upper end of magnetic steel ring is above the upper end of contact pilotage.
Like this, the brushless electric machine circuit board is seated on the stationary shaft, make lead-out terminal on the brushless electric machine circuit board touch contact pilotage on the fixed block, give electrical power, drive magnetic steel ring rotation, the magnetic steel ring of rotation make in the circuit in the utility model and produce Hall effect, by the detection contact on the circuit board, can on oscillograph, see the waveform that is produced, judge the assembly quality of brushless electric machine circuit easily.
Therefore, the utlity model has simple in structure, rationally distributed, easy to use, detection efficiency height, characteristics such as testing result is reliable.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Embodiment
