Problems solved by technology

[0003] 1. The structure of the existing comprehensive tester is complex, so its cost is very high
[0004] 2. The performance of the PG motor can only be judged by observing the feedback waveform with the naked eye for a long time through a comprehensive tester, so testers are prone to visual fatigue or misjudgment
[0005] 3. Since the existing comprehensive tester cannot detect whether the primary and secondary windings of the PG motor are reversed, the detection accuracy of the existing comprehensive monitor is low
[0006] 4. Since the comprehensive tester needs to observe the feedback waveform with the naked eye for a long time to judge the performance of the PG motor, the test efficiency of the existing comprehensive tester is low

Abstract

The invention discloses a tester of a program guidance (PG) motor, which comprises a drive module of the PG motor, a rectification module, a feedback detection module of the PG motor, a display module, a warning module and a single chip computer. The single chip computer is respectively connected with the drive module of the PG motor, the feedback detection module of the PG motor, the display module and the warning module; the drive module of the PG motor and the feedback detection module of the PG motor are both connected with the PG motor; and the power input end of the rectification module is connected with an alternating-current power supply of 220V, and the power output end of the rectification module is respectively connected with the drive module of the PG motor, the feedback detection module of the PG motor, the display module, the warning module and the single chip computer. The tester has low cost, high detection accuracy and high detection efficiency and is not easy to generate visual fatigue.

Description

technical field [0001] The invention relates to a motor testing device, in particular to a PG motor tester. Background technique [0002] PG motor is a stepless speed-adjustable motor with Hall feedback, that is, a motor with speed feedback, which is now commonly used in air conditioners. In order to ensure the quality of PG motors, performance tests such as speed and motor feedback must be performed after the motor is finished. The test device of the existing PG motor is generally a comprehensive tester. During the test, the comprehensive tester is connected with the PG motor, and the waveform of the PG motor is observed through the display to judge whether the performance of the motor is normal. However, in the actual use process, the tester has the following four defects, [0003] 1. The structure of the existing comprehensive tester is complicated, so its cost is very high. [0004] 2. The performance of the PG motor can only be judged by observing the feedback wavefo...
