Problems solved by technology

The disadvantage of this method is that each test requires two-way loading, which not only increases the test time, but also increases the heat generation of the motor, and for some motors, the circuit structure will change at a certain speed position (such as a motor with a centrifugal switch) AC motors), bi-directional testing is not possible

Embodiment Construction

[0053] Such as figure 1 As shown, an existing dynamometer system measurement method is as follows:

[0054] S1. Load a certain load on the motor under test;

[0055] S2. Keep the loading state for a certain period of time;

[0056] S3. Collect multiple sets of performance parameters;

[0057] S4. Calculate the mean value of multiple groups of performance parameters and output.

[0058] In the S2 step of the measurement method, the loading state is kept for a certain time longer than 1 second, that is, the time for keeping the loading state is too long, thereby increasing the testing time; reducing the testing efficiency and increasing the testing cost. Moreover, for the motor, while providing mechanical energy output, it will generate heat energy by itself, which will cause the internal temperature of the motor to rise, and the greater the load on the motor, the more heat energy will be generated, and the entire test process will take too long. As a result, some motors wit...

Abstract

The invention discloses a method, system, device and storage medium for continuous measurement of a dynamometer system. The method for continuous measurement of a dynamometer system is based on the existing measurement method of a dynamometer system, adding inertia correction processing steps, and set the load loading interval and performance parameter sampling interval to a very short time, so that the collected performance parameters can be corrected in real time, that is, the performance parameters can be processed in real time, so that the performance of the motor under test can be improved. The parameters are continuously measured; it not only ensures the test speed, but also ensures the accuracy of the data, which greatly improves the test efficiency and user experience of the motor. The invention can be applied to the technical field of dynamometer systems.

Description

technical field [0001] The invention relates to the technical field of dynamometer systems, in particular to a method, system, device and storage medium for continuous measurement of a dynamometer system. Background technique [0002] When testing the performance of the motor, it is necessary to use the dynamometer system, which mainly increases the load on the motor, and through its electrical properties (voltage, current, input power, power factor, etc.) , torque, output power, etc.) to obtain various performance parameters of the motor from no-load to stalled. [0003] At this stage, there are two main types of dynamometer systems, namely the load brake dynamometer system and the electric power dynamometer system. The load brake dynamometer system is generally used for small and medium-sized motors (<10kW), and consists of a dynamometer (load brake with speed and torque sensors), electrical performance measuring instruments, mechanical performance measuring instrument...
