Background Art:
With the development of the electrical appliance industry, the requirements for the service life and quality of motors are becoming increasingly stringent. In the early stages of motor development, the reliability, stability, and design parameters of the materials must be verified. During the production process, spot checks for life testing on batch orders are required, which necessitates data support. Motor life testing equipment is a professional device for motor testing that provides real-time monitoring of voltage, current, power, and active power, allowing testers to clearly understand the current operating status of the motor. It collects data during the testing period to enable effective analysis of product quality. However, existing technologies cannot perform a one-time test of these data, thus failing to meet people's practical needs.

The present utility model provides a technical solution:A motor life testing device, comprising a cabinet 1, where two leakage switches 2 are fixedly mounted on the lower front of the cabinet 1, and an air switch 3 is provided on the right side of the leakage switches 2. The air switch 3 is fixedly mounted together with the cabinet 1, and the leakage switches 2 and the air switch 3 work together to provide protection for the motor life testing device. Four test cycle counters 4 are fixedly mounted on the upper front of the cabinet 1, and the test cycle counters 4 record the number of rotations of the motor. A start/stop time switch 5 is provided above the test cycle counters 4, and the start/stop time switch 5 is fixedly mounted together with the cabinet 1. A parameter monitor 6 is provided above the start/stop time switch 5, and the parameter monitor 6 is fixedly mounted together with the cabinet 1. The parameter monitor 6 can record various parameters of the motor. Four start/stop control boxes 7 are fixedly mounted on the upper right of the cabinet 1, and four test fixtures 8 are fixedly mounted on the upper left of the cabinet 1. The test fixtures 8 are used to fix the motor to be tested, and the test fixtures 8 comprise a base 801 and a column 802. The bottom of the base 801 is fixedly mounted together with the top of the cabinet 1, and the top of the base 801 is fixedly mounted together with the column 802. A test height adjustment plate 803 is fixedly mounted on the top of the column 802, a coupling 804 is fixedly mounted inside the test height adjustment plate 803, and a connecting plate 805 is fixedly mounted at the bottom of the test height adjustment plate 803. The coupling 804 facilitates the connection between a load shaft 809 and the motor. A bearing housing 806 is fixedly mounted on the top of the coupling 804, and the load shaft 809 is rotatably connected inside the bearing housing 806 via a bearing press plate 808. Two load fan blades 810 are fixedly mounted on the outer wall of the load shaft 809, and the load fan blades 810 are assembled with appropriate loads according to the actual requirements of the product. Protective cover mounting rods 807 are fixedly mounted around the outer wall of the bearing housing 806, and a safety protective cover 811 is fixedly mounted on the top of the protective cover mounting rods 807,The safety protective cover 811 is used to prevent the load fan blades 810 from breaking during high-speed operation, providing a safety protection function. Six supports 9 are uniformly fixedly mounted at the bottom of the cabinet 1, and rubber pads 10 are fixedly mounted at the bottom of the supports 9. The rubber pads 10 increase the friction at the bottom of the supports 9.
When using this motor life testing equipment to test an external motor, first connect the output end of the external motor to be tested with the coupling 804, then adjust the test height adjustment plate 803 to clamp the motor inside the test fixture 8. After that, connect the motor to be tested to an external power supply. As the motor rotates, it drives the load fan blades 810 to rotate through the coupling 804 and the load shaft 809. The load fan blades 810 are assembled with a suitable load according to the actual requirements of the product. The cabinet 1 can be designed as a desktop or multi-layer structure according to usage requirements.
