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.
