Technical Field

[0001] The utility model relates to the technical field of motor controller fixtures, in particular to a motor controller semi-finished product testing fixture. Background Art

[0002] The motor controller includes the main body (protection control function module), mutual inductor detection module, and remote display module. The function modules or accessories of ARD3 can be selected as needed, and the motor control and protection unit can be formed with electrical components such as contactors and motor starters. It has functions such as remote automatic control, direct on-site control, panel indication, signal alarm, and field bus communication. It can meet the production requirements of high speed and high precision by accurately controlling the speed, torque and other parameters of the motor. The intelligent motor controller controls the speed of the motor through frequency conversion technology, and can adjust the working state of the motor at any time within a certain range, which increases the flexibility of the production line. In addition, the intelligent motor controller can set a variety of working modes and set different parameters according to different production processes to ensure the stability of the production process.

[0003] After the motor controller is produced, it is necessary to determine whether the motor controller meets the production requirements. At this time, the current, voltage and speed of the motor controller need to be tested. However, in the actual testing process, the current, voltage and speed are tested using testing equipment respectively, and the testing efficiency is low. It is now urgent to set up a device that can simultaneously detect the current, voltage and speed of the motor controller to improve the testing efficiency. Utility Model Content

[0033] The transmission assembly 4 includes a connecting plate 41 connected to the connecting frame 2, and a sliding sleeve 47 is provided at the bottom end of the connecting plate 41. When the pressure handle 44 is flipped, the pressure handle 44 drives the connecting rod 43 to move downward, and the connecting rod 43 drives the vertical rod 45 to move when moving downward, and the vertical rod 45 can limit the downward movement of the vertical rod 45 through the sliding sleeve 47. A pressure handle 44 is provided on the surface wall of the connecting plate 41, and a vertical rod 45 is provided at the bottom end of the pressure handle 44.
