1. A motor braking performance testing device, comprising:
a motor positioning mechanism configured to position and fix a motor under test;
a linkage mechanism comprising a linkage shaft for linkage with an output shaft of the motor under test and a simulation load for linkage with the linkage shaft;
a power supply for powering the motor under test;
a speed detection module provided on the linkage shaft for measuring the speed of the output shaft of the motor under test;
a timing module configured to count time T1 from the moment when the motor under test receives a braking signal to the moment when the output shaft stops rotating completely;
a standard data storage module configured to store standard default time T0 from the moment when the motor under test receives the braking signal to the moment when the output shaft stops rotating completely;
a data comparison module configured to compare the time T1 obtained by the timing module with the default time T0;
a test result output module which outputs different results based on comparison results of the data comparison module, such as a result that the braking performance of the motor under test is qualified if the T1 is less than the T0, or a result that the braking performance of the motor under test is unqualified; and
a control module configured to control the start-up and braking of the motor under test, wherein the power supply, the speed detection module, the timing module, the standard data storage module, the data comparison module and the test result output module are all electrically connected to the control module.
