Further, a winding positioning column 82 is further provided on the second wire frame 8.
A manufacturing method of an aluminum wire motor stator comprises the following steps:
step one: providing a plurality of main phase iron core assemblies, auxiliary phase iron core assemblies, contact pins 3, enamelled wires 4, a PCB wiring board 5 and a rubber frame 9;
step two: assembling a plurality of main phase iron core assemblies onto a winding connection mechanism 14, winding the enameled wire 4 on each main phase iron core assembly according to a flying fork external winding type winding method, selecting the main phase iron core assembly to be wound, winding the winding starting end of the enameled wire 4 on the contact pin 3 for a plurality of circles, enabling the enameled wire 4 to be tightly connected with the contact pin 3, winding one segmented stator iron core 6, passing through a winding positioning column 82 on the second wire frame 8 at the bottom, continuing to perform winding of the next main phase iron core assembly, and winding the tail end of the enameled wire 4 on the other contact pin 3 after winding to form a main phase winding stator. Similarly, a plurality of the secondary phase iron core assemblies are assembled on the winding connection mechanism 14 for winding according to the winding method to form a secondary phase winding stator. If the motor is provided with a plurality of rotating speed regulation, the motor winding is required to be wound with taps, and at the moment, a plurality of pins 3 are required to be arranged on the first wire frame 7 or the second wire frame 8 so that taps of the enameled wire 4 are wound on the pins 3. The winding mode is a flyer external winding type, the winding type is a concentrated winding, and compared with the traditional winding inserting and falling method of the distributed winding motor, the winding manufacturing speed is faster than a plurality of times.
In addition, when the motor winding is provided with a plurality of taps, since the pin 3 is arranged above the yoke outside the segmented stator core 6, when the tap wire is wound around the pin 3 and then straddles the winding positioning column 82 inside the segmented stator core 6, the jumper is suspended, and the jumper is easy to be broken when the next group of wires is wound again. Here, a winding method is proposed that can solve the above-mentioned broken wire: as shown in fig. 7, let A1 pin be the start winding point of the secondary winding, A2 pin be the secondary winding tap 1 winding point, A3 pin be the secondary winding tap 2 winding point, and A4 pin be the secondary winding tap 3 (which may also be referred to as the secondary winding tail winding point). Let the total number of turns of the secondary winding be N, the number of turns of tap 1 be N1, the number of turns of tap 2 be N2, the number of turns of tap 3 be N3, then there is n=n1+n2+n3. The winding method is that the winding turns are N1 on the first iron core component 10, the second iron core component 11, the third iron core component 12 and the fourth iron core component 13 in sequence, and the tap wire is wound on the contact pin A2. At this time, the next set of tap coils is continuously wound on the fourth iron core component 13, the number of turns is N2, then the number of windings wound on the first iron core component 10, the second iron core component 11 and the third iron core component 12 is N2, when the tap coils are rewound on the fourth iron core component 13, the number of windings wound is N2-N2, and at this time, the tap wires are wound on the contact pin A3. Then continuing to wind the next set of tap coils on the fourth iron core component 13, wherein the number of turns is N3, when the tap coil is wound on the first iron core component 10, the number of turns of winding is N3 because the pin A4 of the tap 3 is arranged on the iron core component, then continuing to wind the second iron core component 11 and the third iron core component 12, the number of turns of the fourth iron core component 13 is 0, and when the tap coil is wound on the first iron core component 10, the number of turns is N3-N3, and the tap coil is wound on the pin A4; thus, the motor winding of the three-gear tap is completed. The number of turns of n2 and n3 is the number of turns required for arranging the coil from the pin side to the inner side of the iron core, and the relation between the turns and the wire diameter d and the slot height hs of the enameled wire 4 is an odd number times (hs/d). The winding method is programmed to be set in the winding mode through a winding program of a winding machine. The method can prevent the tap wire from directly crossing the winding post of the second wire frame 8 from generating suspension and wire breakage from the contact pin 3, so that the winding is tidy, uniform and compact, the utilization rate of the slot area is improved, and the output efficiency of the motor is further improved. The first core assembly 10, the second core assembly 11, the third core assembly 12, and the fourth core assembly 13 may be primary phase core assemblies or secondary phase core assemblies, as will be understood by those skilled in the art.
Step three: after winding is finished, the main phase winding stator and the auxiliary phase winding stator are assembled: firstly, the main phase winding stator and the auxiliary phase winding stator are placed on a winding positioning mechanism for assembly, namely, the convex position 60 on each segmented stator core 6 of the auxiliary phase winding stator is respectively aligned with the concave position 61 on each segmented stator core 6 of the main phase winding stator for insertion, and the winding positioning mechanism is withdrawn after being pressed and flattened by equipment, so that a circular motor stator is formed.
Step four: the assembled motor stator is clamped by a positioning tool fixture and is sent to a laser welding machine, and the joint of each main phase iron core component and each auxiliary phase iron core component is welded, so that each segmented stator iron core 6 is connected and fixed together.
Step five: and (3) carrying out tin immersion on the winding part of the enameled wire 4 and the contact pin 3 of the motor stator so as to remove paint skin and weld, so that the starting point, the tail end and the tap wire of the enameled wire 4 are electrically connected with the contact pin 3. The solder joint is exposed in the air, is easily oxidized by the air and causes the contact point to produce sheet resistance, reduces conductivity, and when electric current passes through, the contact point easily generates heat. The contact is easy to loosen or burn out when seriously overheated, and poor contact or no power is applied. Therefore, in order to ensure stable conductivity of the aluminum wire contact and long service life of the motor, the solder joint is required to be sealed and prevented from oxidation, and then glue filling treatment is carried out. As shown in fig. 2, the glue frame 9 is inserted into a glue groove formed by the first wire frame 7 and the second wire frame 8, at this time, the welding points of the enameled wire 4 and the contact pin 3 are wrapped on the inner side of the glue frame 9 to form a larger glue groove, and glue is injected into the glue groove through a glue dispensing device until the contact point of the enameled wire 4 and the contact pin 3 is completely wrapped and sealed.
Step six: finally, the PCB wiring board 5 is placed on the upper side of the rubber frame 9, the contact pins 3 are inserted into welding holes on the PCB wiring board 5 and are welded in a spot mode to form electric connection, and the PCB wiring board 5 is connected with a power lead wire to be connected with an external power supply.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
