[0023] like Figure 1 and 2 As shown, a servo motor detection device comprises a detection table 1, on which a tooling is arranged, the tooling is used to fix the servo motor, an encoder, an industrial computer, a power analyzer, and a test system control cabinet are installed next to the detection table 1, and after the motor to be tested is fixed, it is connected to the encoder through a coupling, one end of the power analyzer is connected to the motor to be tested, and the other end is connected to the industrial computer; the power analyzer is used to detect the voltage and current data of the motor to be tested and send them to the industrial computer; the industrial computer is also provided with a data acquisition card interface, and a support rod 2 is also arranged on the detection table 1, on which an incandescent lamp 3 is installed, the incandescent lamp 3 is used to irradiate the fixed servo motor, and through the irradiation of the incandescent lamp 3, the lighting environment around the servo motor to be tested is improved, and while performing a no-load test, the appearance of the servo motor can be easily detected, thereby improving work efficiency and reducing the risk of missed detection of products with appearance defects.

[0024] In this embodiment, if Figure 1 and 2 As shown, the support rod 2 is a hollow tube, and the wires of the incandescent lamp 3 pass through the hollow tube. A counterweight 4 is fixed on the wires under the detection table 1.
