Problems solved by technology

[0004] Even so, the above-mentioned rotation balance structure generally has the following problems in fact, for example: (1), the size of the metal sheet of the magnetic sensing part usually corresponds to the magnet (such as a ring magnet) of the magnetic attraction part with a maximum area as much as possible, However, this may cause the magnetically sensitive part and the magnetically attracted part to provide an excessively balanced magnetic force.

Furthermore, although the different magnetically sensitive parts of the same plate are adjacent to each other, they are attracted by the N and S pole regions with different polarities on the rotor, which may cause mutual interference between the magnetically sensitive parts, and then relatively reduce the The actual balance effect of the magnetic sensing part (2). In order to overcome the above-mentioned problems, some known rotational balance structures are provided with several magnetic sensing parts in the form of short pieces separately to appropriately reduce the magnetic force of the magnetic balance, so as to avoid excessive influence on the The rotation efficiency of the rotor. However, the technology of separately setting up several magnetic sensing parts has led to the problem that it is not easy to precisely align and assemble each magnetic sensing part
