Description
Technical field
The present invention relates to a kind of electric machine testing device, specifically is a kind of PG electromechanical testing instrument.
Background technology
The PG motor is a kind of stepless time adjustment motor with the Hall feedback, promptly is a kind of motor of tape speed feedback, now generally uses in air-conditioning.In order to guarantee the quality of PG motor, must carry out the test of performances such as rotating speed and motor feedback behind the motor finished product.The proving installation of existing PG motor is generally comprehensive tester, during test comprehensive tester is connected with the PG motor, observes the waveform of PG motor by display and judges whether motor performance is normal.But in the use of reality, there is the defective of following four aspects in this tester,
1, the complex structure of existing comprehensive tester, so its cost is very high.
2, can judge PG motor properties quality by the comprehensive tester feedback waveform that detects by an unaided eye for a long time, so the tester is easy to produce visual fatigue or erroneous judgement.
3, whether connect anti-problem because existing comprehensive tester can't detect the major-minor winding of PG motor, therefore the detection accuracy of existing comprehensive monitor is low.
4, the feedback waveform can be judged PG motor properties quality because comprehensive tester need detect by an unaided eye for a long time, and the testing efficiency of therefore existing comprehensive tester is low.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defective of above prior art, provide a kind of cost low, be difficult for producing visual fatigue, detection accuracy height and the high PG electromechanical testing instrument of detection efficiency.
Technical scheme of the present invention is, a kind of PG electromechanical testing instrument is provided, and it comprises PG motor drive module, rectification module, PG motor feedback detection module, display module, alarm module and single-chip microcomputer; Described single-chip microcomputer is connected with PG motor drive module, PG motor feedback detection module, display module and alarm module respectively; Described PG motor drive module, PG motor feedback detection module all are connected with the PG motor; The power input of described rectification module is connected with the 220V AC power, and the power output end of described rectification module is connected with PG motor drive module, PG motor feedback detection module, display module, alarm module and single-chip microcomputer respectively.
After adopting above structure, the present invention compared with prior art has the following advantages:
1, because PG electromechanical testing instrument of the present invention is made up of PG motor drive module, rectification module, PG motor feedback detection module, display module, alarm module and single-chip microcomputer, compare with comprehensive tester, its cost is very low.
2, because PG electromechanical testing instrument of the present invention can be judged PG motor properties situation by the chimes of doom of watching display module and alarm module, to compare with the feedback waveform that detects by an unaided eye for a long time, it is difficult for producing visual fatigue or erroneous judgement.
3, can whether connect by the major-minor winding of watching display module to judge the PG motor instead owing to PG electromechanical testing instrument of the present invention, therefore detection accuracy height of the present invention.
4, since PG electromechanical testing instrument of the present invention can be by watching display module rotating speed and the chimes of doom of alarm module can judge PG motor properties situation, compare with the feedback waveform that detects by an unaided eye for a long time, so its testing efficiency is than higher.
As improvement, described display module comprises rotating speed display module and level display module, can watch rotating speed and level display module to watch the high-low level situation by the rotating speed display module respectively, compares with the display module of display screen, not only cost is low, and its detection accuracy further improves.
