[0003] At present, what appears on the market is "to change the moment of inertia of the system by controlling the speed through the centrifugal mechanism". The moment of inertia of this mechanism is related to the speed, and the inertia cannot be changed at a specific speed. It can only change the inertia continuously and cannot change in steps. inertia

The invention provides an inertia testing platform and an inertia testing method for a motor. The inertia testing platform comprises a platform base, a rotating shaft, a double-electromagnetic clutchand an inertia disc set, wherein the rotating shaft, the double-electromagnetic clutch and the inertia disc set are arranged above the platform base, the inertia disc set comprises a first inertia disc and a second inertia disc, and the double-electromagnetic clutch is fixedly connected with the platform base; the rotating shaft is transversely arranged above the platform base and arranged in thedouble electromagnetic clutches in a penetrating mode; and the first inertia disc and the second inertia disc are arranged on the two sides of the double-electromagnetic clutch, and are rotatably arranged on the rotating shaft through inertia disc connectors of the double-electromagnetic clutch respectively. The double-electromagnetic clutch controls the connection / separation of the rotating shaftand the first inertia disc and / or the second inertia disc by attracting / separating the inertia disc connectors so as to realize the step change of the load inertia in the motor testing process.
Description
technical field [0001] The invention relates to motor testing technology, in particular to an inertia testing platform and an inertia testing method for a motor. Background technique [0002] Servo motors are used more and more widely, such as CNC machine tools, robots, aviation, military and other fields. However, in the selection process of servo systems, in addition to the rated torque and rated speed of the motor, the rotation of the load must also be considered. Inertia, the inertia of the motor is more important than the parameter setting, and it is an important prerequisite for giving full play to the best performance of the entire mechanical and servo system; the size of the load inertia affects the sensitivity and accuracy of the entire servo drive system, and the load inertia determines the servo drive. Parameter setting, how to correctly set the parameters of the servo drive, how to select the servo motor according to the sensitivity and precision of the servo sys...
