Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a novel variable-frequency motor. Background Art

[0002] Landslides are collapse phenomena that occur when rocks are affected by gravity. They often occur in steep mountainous areas. When a landslide occurs, there are bursts of loud noises, smoke and dust fill the air, and the rocks quickly break apart and collapse downward. Landslides can cause great disasters. After a landslide occurs, a large amount of rock and soil blocks fall into the river, which can also block the river and cause flood disasters. Therefore, it is of great practical significance to monitor and warn the mountain body; the existing technology mainly uses the traditional servo + planetary reduction structure to control the rotation of the central control platform to complete geological monitoring, with poor use effect, large floor area, and high cost, which cannot meet the long-term use needs of people, and it is easily affected by pollutants such as dust, dirt, and grease during the working process;

[0003] In view of the above situation, it is necessary to improve the existing geological monitoring control method so that it can meet the current needs of geological monitoring. Summary of the Utility Model
