The invention belongs to the field of hydraulic transmission and control and relates to a hydraulic loading motor performance testing experiment system and an experiment method. The hydraulic loading motor performance testing experiment system comprises a motor performance parameter detection system, a torque rotation speed sensor and a hydraulic loading device system, wherein the motor performance parameter detection system further comprises a current sensor, a voltage sensor, a data acquisition unit and a data processing unit. The torque rotation speed sensor detects the rotation speed and torque of a motor. The hydraulic loading device system conducts loading on the motor. The hydraulic loading motor performance testing experiment system uses a constant-voltage variable pump as a loading pump, the working pressure of a hydraulic pump is basically constant during loading, a proportional flow valve serves as a control element, and loading is performed by adjusting output flow of the loading hydraulic pump. The loading mode is simple, a loading device is small in rotational inertia and can perform static, dynamic and continuous loading, the working pressure value of the loading hydraulic pump can be set in the loading process according to the actual situation and is basically constant, loading is sensitive, reliable and stable, and meanwhile the loading stability is good when the rotation speed of the motor is low.
