Hysteresis dynamic pressure motor performance test system and test method

The invention discloses a hysteresis dynamic pressure motor performance test system, and the system achieves the automatic collection of a back electromotive force waveform signal through a data collection card. And motor performance parameters such as load torque, inertia time, friction torque, contact speed and the like in the whole stalling and sliding process of the motor are obtained by utilizing a dynamic pressure motor test module according to a calculation method of motor principle rotating speed and friction torque. The invention further discloses a testing method based on the hysteresis dynamic pressure motor performance testing system. The method solves the problems that the dynamic pressure motor performance test only depends on a single index of inertia time and the fault diagnosis is difficult in the whole table stage of the mechanical gyroscope table, realizes the dynamic pressure motor performance test of the gyroscope table, and has the advantages of convenience and simplicity in operation, h
