Description

Technical Field

[0001] The utility model belongs to the technical field of teaching instruments, and particularly relates to a motor unit training platform. Background Art

[0002] Motor control involves three-phase squirrel-cage asynchronous motors, three-phase synchronous generators, DC generators, DC motors, etc. Currently, the existing motor unit teaching training platforms on the market generally adopt different structural designs when completing motor trainings with different functions. The structural forms are diverse. When schools build laboratories, they need to purchase multiple equipment platforms. On the one hand, it increases the construction investment, and on the other hand, it also occupies more space in the laboratory. There is a lack of a general-purpose equipment platform on the market that can meet different training function requirements.

[0003] In addition, in the past motor learning experimental teaching, it was too limited to textbook knowledge and lacked certain practical guidance. Many students paid more attention to theoretical courses and lacked practical operations, resulting in unsatisfactory experimental effects. This requires students to combine theory and practice.

[0004] The Chinese patent document with the publication number CN209729107U discloses a high-power AC asynchronous motor fault diagnosis training platform, which includes an operation console, a base, an electrical cabinet, a host computer, an AC asynchronous motor, and a magnetic particle brake. The operation console is connected to the electrical cabinet through a cable, the electrical cabinet is connected to the host computer through a network cable, the electrical cabinet is connected to the AC asynchronous motor through a cable and a signal line. The AC asynchronous motor is installed on the base. A coupling is provided on the AC asynchronous motor, the coupling is connected to a sensor through a clutch, the sensor is installed on the magnetic particle brake, and the magnetic particle brake is installed on the base. This utility model can simulate the motor operating state when the AC asynchronous motor has common faults and obtain relevant motor parameters, so that students can intuitively understand the fault characteristics of the AC asynchronous motor and get the practical opportunity of motor fault diagnosis.

[0005] In the above patent solution, one training platform is only for one type of motor. However, in teaching tasks, students are often required to understand different types of motors. Adopting the above solution will greatly increase the number of training platforms and the area of the training site, which also means an increase in the corresponding teaching costs. However, except for the motors, many components on the training platform are the same or similar. Therefore, the increase in teaching costs has not been transformed into teaching achievements, but into redundant components, resulting in a great waste of resources. Content of the Utility Model

If additional training functions are required in the later stage, relevant motors can be added, and the motors required for experiments can be freely replaced on the training platform. The training functions of multiple equipment platforms on the current market can be completed with one equipment platform, reducing the investment cost of training construction and the area of training sites.
