The stator consists of a stator core, a stator winding, and a frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic field lines in the rotating magnetic field to generate (output) current. The Chinese motor parts market is distributed in the southeastern coastal areas and the Yangtze River Delta region.

[0003] The current segmented motor stator structure assembly, as described in the patent with the publication number CN202111540U, is composed of multiple iron core sheets; the iron core sheets are quarter-circular thin sheets, and multiple tooth grooves are formed by inward depressions on the inner arc edges of each iron core sheet. Four iron core sheets form a group to form a ring, and then multiple groups of rings are stacked together, and the joints on adjacent rings are staggered.

[0004] Regarding the above related technologies, the inventor believes that setting the grooves for the windings to bypass inside the segmented stator core makes the operation inconvenient when disassembling and assembling the windings because the internal space of the segmented stator core is narrow.

[0025] The technical solution of this patent will be further described in detail below in conjunction with the specific implementation mode

[0026] Please refer to Figures 1-4 , a sectional motor stator structure component, including an inner stator mechanism 1. The inner stator mechanism 1 includes an inner iron core 101. A plurality of grooves 102 are formed in a circumferential array on the outer side of the inner iron core 101. A plurality of connecting ribs 103 are fixedly connected in a circumferential array on the outer side of the inner iron core 101. A plurality of windings 104 are wound around the outer side of the inner iron core 101 in a circumferential array. Each group of windings 104 is arranged inside the groove 102. The groove 102 is provided for accommodating the winding 104. The inner iron core 101 includes end pieces 1012 respectively arranged on both sides inside the outer iron core 201. A plurality of first screws 1014 penetrate through the two groups of end pieces 1012 in a circumferential array. The end pieces 1012 can limit the iron sheets 1011, so that grooves 102 are formed between adjacent two iron sheets 1011

[0027] First insulating tubes 1016 are sleeved on the outer sides of the two groups of first screws 1014. Each group of first insulating tubes 1016 penetrates through the iron sheets 1011 and the end pieces 1012. The first insulating tubes 1016 can separate the iron sheets 1011 and the end pieces 1012 from the first screws 1014, thus playing an insulating role. A plurality of iron sheets 1011 penetrate through the outer sides of each group of first screws 1014. The iron sheets 1011 of each group are in contact with each other. First nuts 1015 are symmetrically threadedly connected to the outer sides of each group of first screws 1014. The first nuts 1015 can limit the end pieces 1012, so as to clamp and fix each group of iron sheets 1011

[0028] Insulating gasket rings 1013 are symmetrically arranged on the opposite sides of the two groups of end pieces 1012. Each group of first screws 1014 passes through the insulating gasket rings 1013 on both sides, and the first nuts 1015 on both sides are respectively in contact with the insulating gasket rings 1013 on both sides. The setting of the insulating gasket rings 1013 can separate the first nuts 1015 from the end pieces 1012, thus playing an insulating role. The outer stator mechanism 2 includes an outer iron core 201 sleeved on the outer side of the inner iron core 101. A plurality of slots 204 are formed in the inner wall of the outer iron core 201 in an annular array. Each group of connecting ribs 103 are respectively inserted into the interiors of the slots 204. The setting of the slots 204 can allow the connecting ribs 103 to be inserted. After the connecting ribs 103 are inserted into the slots 204, the outer iron core 201 can block each group of grooves 102, thus realizing the function of isolating and protecting the winding 104.

[0029] The connecting ribs 103 are detachably connected to the outer iron core 201. A plurality of second screws 202 penetrate through the outer iron core 201 in an annular array inside the outer iron core 201. A second insulating sleeve 205 is sleeved on the outer side of the second screw 202. Each group of second insulating sleeves 205 passes through the outer iron core 201. The setting of the second insulating sleeves 205 can separate the outer iron core 201 from the second screws 202, thus playing an insulating role. Retaining rings 203 are arranged on both sides of the outer iron core 201. The second screws 202 pass through the retaining rings 203. The setting of the retaining rings 203 can limit the connecting ribs 103 to reduce the probability of the connecting ribs 103 disengaging from the interiors of the slots 204. A plurality of second nuts 206 are arranged in an annular array on the side of the retaining ring 203 away from the outer iron core 201. The second nuts 206 are adapted to the second screws 202. The setting of the second nuts 206 is used to limit the retaining ring 203 after being screwed onto the outer side of the second screw 202. Pulling rings 207 are fixedly connected to the outer sides of each group of second nuts 206 on one side. The setting of the pulling rings 207 can facilitate the traction of the second nuts 206, making it convenient to pull the entire stator out of the interior of the motor housing when disassembling and assembling the entire stator.

[0030] When in use, when the winding 104 is damaged and needs to be replaced, the motor cover can be opened. First, remove the rotor of the motor, then remove the connection between the outer iron core 201 and the motor housing. Then, fix a rope or a hook on the pull ring 207. Then, the entire stator can be pulled out of the motor housing through the rope or the hook. Next, the second nuts 206 on one side can be unscrewed, and then the outer iron core 201 can be removed from the outside of the connecting rib 103. Then, the damaged winding 104 can be disassembled from the outside of the inner iron core 101. Next, a new winding 104 can be replaced. Since the outer iron core 201 is removed, space is provided for the disassembly and assembly of the winding 104, making the disassembly and assembly of the winding 104 more convenient. Then, the connecting ribs 103 can be aligned with the slots 204, and then the outer iron core 201 can be sleeved on the outside of the connecting rib 103 again, and the second nut 206 can be tightened again.

Any person with ordinary knowledge in the technical field can, without departing from the technical features of the present invention, make equivalent embodiments with partial changes or modifications using the technical content disclosed in the present invention, and without departing from the technical feature content of the present invention, still fall within the scope of the technical features of the present invention.
