  • Publication number: 20240219467
    Abstract: A full-open and full-angle stall device for a motor test system is disclosed. The stall device is used to provide a stall function to a motor under test and includes a base, a driving source connection module and a brake module. The driving source connection module includes a coupling and a first disc and a second disc that are detachably joined together. The first disc and the second disc are fixed on the coupling. The coupling is defined with a mounting hole for connecting a transmission shaft so as to receive a driving source from the motor under test. The brake module is disposed on the base and is configured at an edge of the driving source connection module, and is controlled to generate a clamping force on the driving source connection module, wherein the clamping force is selectively applied to any edge of the first disc and the second disc so as to brake the driving source connection module.

  • Patent number: 8179138
    Abstract: A cathode ray tube (CRT) test system for testing a CRT device is disclosed. The CRT test system comprises a connecting device, a power module, a control module, a first test module, and an illumination module. The connecting device detachably and electrically connects with the CRT device; the power module electrically connects with the connecting device; the control module electrically connects with the connecting device; and the control module comprises test program. After the CRT device receives a control signal transmitted from the test program, the CRT device generates a response signal and transmits the response signal to the first test module. When the first test module detects that the control signal and the response signal fit in with a first test signal status, the illumination module displays a first light sign; when the control signal and the response signal do not fit in with the first test signal status, the illumination module displays a second light sign.
