[ first embodiment ] A method for manufacturing a semiconductor device

Referring to fig. 1, a four-pole dc motor 100 according to a first embodiment of the present invention includes: a rotor assembly 10, a stator assembly 50 circumferentially distributed about the rotor assembly 10, and a winding (not shown) wound on the rotor assembly 10.

Specifically, referring to fig. 2, 3 and 9, the rotor assembly 10 is provided with twenty circumferentially distributed winding shafts 13 and twenty rotor hole slots 15 arranged among the twenty winding shafts 13; wherein, one rotor hole slot 15 is formed by two adjacent winding shafts 13, or one rotor hole slot 15 is formed between two adjacent winding shafts 13, and the diameter D of the rotor assembly 10 is 89-91mm, preferably, the diameter D of the rotor assembly 10 is set to be 90 mm.

The stator assembly 50 includes, for example, four permanent magnets 51, the four permanent magnets 51 being circumferentially distributed around the rotor assembly 10; wherein, a space is provided between two adjacent permanent magnets 51.

The four-pole dc motor 100 has an advantage of high efficiency compared to a two-pole dc motor used in the existing household food waste disposer, and at the same time, it can be applied to the household food waste disposer to increase its output power to thereby improve waste disposal efficiency.

Preferably, referring to fig. 4 and 5, each permanent magnet 51 may be a magnetic tile, a width L of each magnetic tile is 44-54mm, and a height h of each magnetic tile is 34-48 mm. For example, each permanent magnet 5 may be a ferrite magnetic shoe, a neodymium iron boron magnetic shoe, or an alnico magnetic shoe, respectively; during the application process, the permanent magnet 5 can provide a magnetic action field with constant and certain intensity, and has the capacity of maintaining the magnetic action field in a demand environment; at the same time, the size of the magnetic shoe can maintain the magnetic action strength, and the overall installation size of the four-pole dc motor 100 assembled by the magnetic shoe and the rotor assembly 10 is further reduced.

Preferably, referring to fig. 2 and 3, the rotor assembly 10 is further provided with a rotating shaft accommodating cavity 16, and accordingly, the four-pole dc motor 100 further includes: the rotating shaft 70 is sleeved in the rotating shaft accommodating cavity 16, and the rotating shaft 70 is also fixedly connected with the rotor assembly 10. For example, the rotating shaft 70 is inserted into the rotor accommodating cavity 16 from the rotor accommodating cavity 16 at an opening at one end of the rotor assembly 10; in operation of the rotor assembly 10, power output is achieved through the shaft 70 within the shaft receiving cavity 16.

Preferably, referring to fig. 3, the rotor assembly 10 further includes, for example: rotor body 11 and at least two rotor punching 12. Specifically, the rotor body 11 is provided with twenty winding shafts 13 and twenty rotor hole slots 15; twenty positioning shafts 1202 corresponding to the twenty winding shafts 13 are circumferentially distributed on each rotor punching 12, twenty positioning gaps 1201 are arranged between the twenty positioning shafts 1202, and the twenty positioning gaps 1201 are in one-to-one correspondence with the twenty rotor hole slots 15; the rotor book 11 and each rotor punching sheet 12 are provided with coaxial rotating shaft accommodating cavities 16 for connecting the rotating shaft 70; each rotor punching sheet 12 is respectively matched with the end face of the rotor body 11 and respectively covers two opposite end faces of the rotor body 11.

Further, the rotor body 11 is further provided with four magnetic member accommodating cavities 14, and correspondingly, the rotor assembly 10 further includes four magnetic members (not shown in the drawings) respectively installed in the four magnetic member accommodating cavities 14 in a matching manner; wherein, a rotor hole slot 14 is arranged between two adjacent magnetic piece accommodating cavities 14. The four magnetic members increase the magnetic field strength of the rotor assembly 10, and increase the output torque of the four-pole dc motor 100.

Preferably, a winding baffle 17 is connected to each of the winding shafts 13 near one end of the stator assembly 50, and the winding baffle 17 is used to further limit the winding position of the winding groups on the winding shafts 13 and prevent the winding groups from slipping off the winding shafts 13. An opening is formed between two adjacent winding baffles 17 to facilitate winding of the winding groups; the openings are communicated with the rotor hole slots 15 clamped between the two corresponding winding shafts 13, circulation of air flow inside and outside the rotor hole slots 15 is promoted, and the heat dissipation effect is improved.

Preferably, referring to fig. 6 and 7, the four-pole dc motor 100 further includes, for example: a diverter assembly 60 and a brush holder assembly 40.

Specifically, the reversing assembly 60 is also connected to the rotating shaft 70, and the rotor assembly 10 drives the rotating shaft 70 to rotate and simultaneously drives the reversing assembly 60 to rotate; the commutation assembly 60 is provided with forty commutator segments 61.

The brush holder assembly 40 is provided with a reversing assembly opening 42 and four electric brushes 41, and an included angle formed by two adjacent electric brushes 41 is 90 degrees; each two of the brushes 41 disposed opposite to each other are grouped, and thus the four brushes 41 are divided into two groups; one set of the brushes 41 is electrically connected with a positive power line, and the other set of the brushes 41 is electrically connected with a negative power line; the brush holder assembly 40 is sleeved outside the reversing assembly 60 through the reversing assembly opening 42, and the four brushes 41 are respectively contacted with at least two reversing sheets 61 of the forty reversing sheets 61.

Because in the working process of the four-pole direct current motor 100, when the brush 41 slides at a high speed relative to the surface of the commutator segment 61, sparks and electric arcs are caused, the surface of the brush 41 is abraded, and the resistance change is influenced, by arranging the forty commutator segments 61 in the circumferential direction, compared with a two-pole direct current motor used by the existing household food waste disposer, the number of the commutator segments 61 is increased to be twice of that of the rotor hole grooves 15, the sliding distance between the adjacent commutator segments 61 is reduced, the influence of the brush 41 on the surface of the commutator segment 61 in the high-speed sliding process is smaller, and the stability of the four-pole direct current motor 100 is improved.

The specific operation of the four-pole dc motor 100 is, for example: when the winding is energized, the rotor assembly 10 rotates under the action of the permanent magnet 50 through the attraction and repulsion forces, when the rotor assembly 10 rotates to be balanced with the permanent magnet 50, the originally energized winding is separated from one set of brushes 41 (two brushes 41 are one set) in the brush holder assembly 40 than the commutator segment 61 on the corresponding commutator assembly 60, and the other set of brushes 41 is connected to the commutator segment 61 corresponding to the winding set generating the driving force, so that the four-pole direct current motor 100 repeatedly rotates.

Preferably, referring to fig. 8, the four-pole dc motor 100 further includes, for example, a housing 20, the housing 20 being sleeved outside the positioning assembly 50, such that the positioning assembly 50 is sandwiched between the housing 20 and the rotor assembly 10; one side of the casing 20, which is in contact with the stator assembly 50, is provided with four limiting members 21 corresponding to the four permanent magnets 51 one by one, and the four limiting members 21 are used for limiting the four permanent magnets 51 respectively and are used for positioning the four permanent magnets 51 so that the four permanent magnets 51 can be mounted at a proper height at one time.

Specifically, the four-pole dc motor 100 further includes a housing disposed outside the stator assembly; four limit pieces are circumferentially distributed at the position of the shell corresponding to the stator assembly; the four permanent magnets respectively correspond to the four limiting parts and are clamped between the shell and the rotor assembly.

Preferably, the four-pole dc motor 100 further includes, for example, the fixing assembly 30, which greatly increases the tightness of the connection between the rotor assembly 10, the stator assembly 20, the brush holder assembly 40, and the commutation assembly 60, and reduces noise generated during rotation of the four-pole dc motor 100.

Specifically, the fixing member 30 includes, for example, two cover plates 31 respectively covering both ends of the housing 20, and a fastening member 32 fastening and connecting the two cover plates 31. For example, the fastening member 32 includes a plurality of bolt connection members, the two cover plates 31 are respectively provided with a plurality of threaded connection holes, and the plurality of bolt connection members respectively sequentially pass through the plurality of threaded connection holes of the two cover plates 31, so as to fasten and connect the two cover plates 31, the rotor assembly 10, the stator assembly 20, the brush holder assembly 40, and the reversing assembly 60, which are clamped between the two cover plates 31, thereby improving the tightness of the above structure.
