Problems solved by technology
[0007] The disadvantages are: there is a ticking sound, and the volume is large. Although there are also miniature ones, the cost of the miniature ones is high due to the high precision of the production requirements, and because of the miniature size, its rotational force is small, and it cannot move the larger effectors.
Therefore, it is not suitable to drive some effectors that require a large driving force
