Through the above-mentioned mode, the adjustable load assembly increases the load with different weights for the piston of the hydraulic cylinder to be detected, which facilitates the detection personnel to master the partial load synchronous ability of the synchronous shunt motor to be detected; the resistance type synchronous detection assembly can greatly reduce the error of the detection result, ensuring that the detection personnel accurately master the result of detection and calibration.
