As long as it can fix the motor 9, no further limitation is made here.

[0029] The test bench 100 of the technical solution of the utility model includes a base 1, an air-cooled hysteresis brake 2, an air-cooling component 3 and a fixture component 8.

[0032] In the embodiment of the present invention, the test bench 100 further includes a pressure regulating valve 4 , which is disposed between the vent pipe 31 and the air-cooled hysteresis brake 2 to adjust the air pressure in the vent pipe 31 .

[0033] In this embodiment, a pressure regulating valve 4 is provided between the vent pipe 31 and the air-cooled hysteresis brake 2. By adjusting the pressure regulating valve 4, the flow rate of the gas in the vent pipe 31 is adjusted, and finally the cooling effect of the air-cooled component 3 on the air-cooled hysteresis brake 2 is adjusted. The cooling effect can be adjusted according to the working temperature of the air-cooled hysteresis brake 2, which can prevent the air-cooled hysteresis brake 2 from burning due to heat, achieve the effect of outputting stable load torque, improve the reliability and stability of the motor 9 test, and reduce the power consumption and gas consumption of the air-cooled component 3.

[0035] In this embodiment, a pressure detection component 5 is arranged between the pressure regulating valve 4 and the air-cooled hysteresis brake 2, which can directly obtain the air pressure value in the intake pipe, and then directly obtain the gas flow value in the intake pipe. According to the air pressure value, the gas flow in the intake pipe is adjusted by the pressure regulating valve 4 to adjust the cooling effect, which can prevent the air-cooled hysteresis brake 2 from burning due to heat, achieve the effect of outputting stable load torque, improve the reliability and stability of the motor 9 test, and reduce the power consumption and gas consumption of the air-cooled component 3.

[0037] In this embodiment, the electric contact pressure gauge is electrically connected to the air-cooled hysteresis brake 2, and a lower limit value of the electric contact pressure gauge is set. When the electric contact pressure gauge detects that the gas pressure value in the intake pipe is less than the set lower limit value, it means that the gas flow in the intake pipe is insufficient, which may be insufficient to cool the air-cooled hysteresis brake 2. At this time, it is necessary to urgently stop the operation of the air-cooled hysteresis brake 2 to prevent the air-cooled hysteresis brake 2 from burning due to heat.

By changing the relative position between the first slider 81 and the first slide groove, the distance between the clamping portion 83 and the air-cooled hysteresis brake 2 is changed, and finally the distance between the test motor 9 and the air-cooled hysteresis brake 2 is changed, so that the test of the test motor 9 with different shaft lengths can be adapted. The relative sliding of the clamping portion 83 relative to the base 1 along the width direction of the base 1 is realized by the sliding cooperation between the second slider 82 and the second slide groove provided on the first slider 81. By changing the relative position between the second slider 82 and the second slide groove, the distance between the test motor 9 and the air-cooled hysteresis brake 2 along the width direction of the base 1 is changed, so that the test of the test motor 9 with different widths can be adapted.
