Abstract: The present invention relates to a transmission mechanism and an anti-blocking motor. The transmission mechanism includes a first moving member for receiving a torque and a second moving member for outputting the torque. The second moving member is sleeved on the circumferential outer side of the first moving member, and forms a linkage cavity. A plurality of linkage blocks are arranged inside the linkage cavity. When the first moving member rotates, the linkage blocks come into contact with the second moving member due to centrifugation, and realize the linkage between the first moving member and the second moving member. The present invention has the advantage of avoiding damage from blockage, and the present invention is simple in structure, convenient to assemble, convenient for subsequent maintenance, not easy to break and long in service life.

Abstract: The present invention relates to a motor braking performance testing device, comprising: a motor positioning mechanism, a linkage mechanism, a power supply, a speed detection module, a timing module, a standard data storage module, a data comparison module, a test result output module, and a control module. 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. The present invention has the advantages that the device can test the braking performance of high-speed motors such as motors of lawn mowers, and make test results more accurate.
