[0021] A motor performance testing device, such as Figs. 1-2As shown, the device includes a workbench 1 and an airtightness tester 2. The airtightness tester 2 is located to the right of the workbench 1. Four support columns 3 are fixedly installed on the upper end of the workbench 1. A support plate 4 is fixedly installed on the upper end of the four support columns 3. A first cylinder 5 is fixedly installed on the middle side of the upper end of the support plate 4.

An arc-shaped clamping plate 13 is fixedly installed on the output end of each of the two second cylinders 12. The motor 10 is located between the two arc-shaped clamping plates 13.

[0022] like Fig. 1 As shown, four support legs 14 are fixedly installed at the lower end of the workbench 1, which provide support and stability to the workbench 1.

[0023] like Fig. 1 As shown, a guide rod 15 is fixedly installed on both the left and right sides of the upper end of the movable plate 6. The guide rod 15 and the support plate 4 are movably interlocked.
