It generally includes a casing, a stator, a rotor and a rotating shaft. The rotating shaft can output power to drive the power machinery to work. At present, the rotating shafts of existing motors are generally solid structures, and the motors of this structure can be applied to power machinery in various fields. However, the motor has at least the following defects: the solid structure of the shaft has a high cost, and the power machinery (including bead grinding machines, etc.) connected to it can only be connected to its end, resulting in a waste of space resources , that is to say, after it is connected with the power machinery, the volume of the whole machine is relatively large

In addition, crystal is a colorless and transparent large-scale quartz crystal mineral, which generally needs to be polished on the surface. The grinding methods include various processing methods including manual grinding and bead grinding machine grinding. Manual grinding will inevitably result in defective products. The efficiency is high, the cost is high, and the technical level of the workers is too high, which is not suitable for large-scale industrial production; while the existing bead grinding machines generally include a frame with a grinding disc on the frame, and the grinding disc is connected to the lifting mechanism. , the advantage of this solution is that the grinding disc can be lifted and lowered automatically, which virtually reduces the operator's work intensity. In addition, the bead grinding machine with this structure not only replaces manual operation, but also further improves production efficiency and reduces production costs. Cost, etc., but this bead grinding machine also has at least the following defects: the volume of the whole machine is large and the structure is not compact, that is to say, the space area required for its installation is relatively large, which causes a certain waste of existing space resources; In addition, the manufacturing cost of the existing bead grinding machine is relatively high, which does not conform to the current trend of social technology development

[0004] The above two solutions have improved some problems of the prior art to a certain extent, however, the rotating shafts of the main motor and the vertical stepping motor of the first solution are solid structures, and the rotating shafts of the translational motors of the second solution are also solid structures , its cost is relatively high, and both of these two solutions have at least the following defects. The structure of the whole machine is complex and not compact, that is to say, the volume of the whole machine is relatively large, which virtually increases the cost of production and manufacturing. In addition, the work is stable sex is also poor
