[0002] In the field of motor research and development, production and quality testing, the temperature rise performance of motor is a key indicator for measuring its operational reliability and service life. Under different loads or operating conditions, the temperature changes of components such as the windings and iron core of the motor are significantly different. Therefore, it is necessary to conduct temperature rise tests by simulating various operating conditions in order to comprehensively evaluate the motor's heat dissipation capacity and safe operating boundaries.

[0003] Most motor temperature rise testing devices can only provide basic fixing functions for the motor and cannot flexibly adjust the load size to adapt to the testing needs under different load conditions. Although the load condition can be adjusted by disassembling the load components, the process of manually disassembling the original load components and reinstalling the new load structure is time-consuming and requires frequent shutdowns, which seriously affects the testing efficiency. In order to solve the above problems, the inventors proposed a simple motor temperature rise testing device. Utility Model Content

A rotating shaft 34 is rotatably connected to the bottom end of the top plate 32. A mounting box 35 is symmetrically fixed to the outer ring of the rotating shaft 34 near the bottom center. A rotating shaft 36 is rotatably connected to the side of the mounting box 35 away from the rotating shaft 34. Several load rings 38 are provided on the outer ring of the rotating shaft 36. The number of load rings 38 on the two rotating shafts 36 is different and needs to be selected according to the actual use requirements, so as to realize the load conditions under different states. The electrical components in this application and their matching power supply are electrically connected through wires. And a suitable controller should be selected according to the actual situation to meet the control requirements. The detailed connection method is a well-known technology in the field.

[0021] A coupling 37 is provided on the side of the rotating shaft 36 away from the rotating shaft 34.

[0022] By adopting the above technical solution, coupling 37 can be connected to the output end of the motor to begin the motor temperature rise test.

[0023] A motor 33 is installed at the top of the top plate 32, and the output end of the motor 33 passes through the top plate 32 and is fixedly connected to the rotating shaft 34.

[0024] By adopting the above technical solution, the working motor 33 is operated, thereby causing the fixedly connected rotating shaft 34 to rotate.

[0025] An electric cylinder 31 is provided on one side of the support frame 3 near the bottom of the mounting box 2, and the output end of the electric cylinder 31 is fixedly connected to the mounting box 2.

[0026] By adopting the above technical solution, the output end of the electric cylinder 31 is fixedly connected to the mounting box 2 through the flange, which can drive the mounting box 2 to slide horizontally along the base plate 1.

[0027] A circular groove 24 is provided near the center of one side of the mounting box 2, which is close to the support frame 3.

[0028] By adopting the above technical solution, a circular groove 24 is opened on the side of the mounting box 2 to facilitate the connection of the motor output end with the coupling 37.

[0029] Two sets of mounting holes 23 are symmetrically opened at the bottom of the mounting box 2 near the center.

[0030] By adopting the above technical solution, two sets of mounting holes 23 are set at the bottom of the mounting box 2 to fix different models of the motor under test.

[0035] Working principle: When using this device, first place the motor that needs to be tested for temperature rise inside the mounting box 2, and limit the motor by matching the mounting holes 23 and bolts. Then select the required load state, and connect the appropriate rotating shaft 36 to the motor output end through the coupling 37, thereby starting the working motor 33. This causes the fixedly connected rotating shaft 34 to drive the two mounting boxes 35 to rotate (only 180 degrees need to be rotated each time the rotation is adjusted), thereby adjusting the position of the two rotating shafts 36 with different load rings 38, so as to simulate the working state of the motor under different loads or operating conditions.

[0036] After working for a period of time, the temperature of the motor can be measured by the temperature monitor 26 under the sliding block 25. By activating the working electric push rod 27, the fixedly connected sliding block 25 drives the temperature monitor 26 to move horizontally, thereby measuring the temperature of different positions of the motor (casing, output shaft) so as to truly reflect the temperature change of the motor under actual use conditions.
