AI Technical Summary
In the existing technology, the lack of fixed guidance during the testing of submersible motors causes the motor shaft and the top of the ballast device to be unable to remain coaxial, affecting the accuracy of the test results. Furthermore, the distance between the motor shaft and the ballast device cannot be guaranteed to be uniform for motors of different heights.
A motor testing and fixing guide device was designed, including a device body and a height adjustment block. Through the cooperation of the positioning component and the height adjustment block, the motor is fixed in the water tank and the motor shaft is kept coaxial with the ballast device, which can meet the needs of motors of different heights.
This ensured accurate positioning of the motor during testing, guaranteeing that the axial load was perpendicular to the motor end face, thus ensuring the accuracy and consistency of the test results.
