The upper end of the silicon steel sheet 1 is provided with an upper contact pin 8, the lower end of the silicon steel sheet 1 is provided with a lower contact pin 9, the upper contact pin 8 is inserted into the top cover 6, the lower contact pin 9 is inserted into the bottom cover 7, and the connection between the silicon steel sheet 1 and the top cover 6 and the bottom cover 7 is very stable due to the connection mode.
The upper pin 8 and the lower pin 9 can be integrated pins, and the pins penetrate through the silicon steel sheet 1, the upper exposed part forms the upper pin 8, and the lower exposed part forms the lower pin 9. Of course, the upper pin and the lower pin can be separated, but the preferable scheme is also integrated.
Generally, the cross section of the silicon steel sheet 1 is U-shaped, that is, the silicon steel sheet is composed of side plates 10 at two sides and a web plate 11 located between the side plates, at this time, the upper pin 8 is located at the upper end of the side plates at two sides, the lower pin 9 is located at the lower end of the side plate at the other side, and the coil 2 is wound on the web plate 11 of the silicon steel sheet.
In the embodiment, the silicon steel sheet 1 is provided with the rubber coating 1, and the rubber coating 12 fixes the upper contact pin 8 and the lower contact pin 9, so that the upper contact pin 8 and the lower contact pin 9 are fixed more stably. In this embodiment, the edges of the silicon steel sheet 1 are completely coated by the coating, so that when the coil 2 is wound on the web 11 of the silicon steel sheet, the coil 2 is simultaneously wound on the coating on the edges of the web, and the coating on the edges of the web protects the coil 2 to prevent the coil 2 from being cut and damaged by the edges of the web.
In this embodiment, the lower portion of the magnet mounting member 3 is connected to the bottom cover 7 in the following specific connection manner: the lower part of the magnet mounting part 3 is provided with a lower elastic part 13, the lower elastic part 13 is inserted into the bottom cover 7, the lower elastic part 13 is inserted into the bottom cover, an insertion slot is arranged on the bottom cover 7, and then the lower elastic part 13 is inserted, or the lower elastic part 13 and the bottom cover are injected together. The lower elastic member 13 may be generally configured as a spring sheet, and due to the configuration of the elastic member, the rotor may have a buffer effect during rotation, so that the rotor may feel better when being applied to the field of, for example, an electric toothbrush, and may generate less noise when being vibrated.
