Description of the invention [Technical field to which the invention belongs] The present invention relates to a rotor-type motor formed by winding an electromagnetic coil around each magnetic pole tooth of a stator core and y-type wiring, and a method for manufacturing the same, in more detail. , Is a technology that can shorten the time of coil winding work and wiring work. ^ [Prior art] As shown in Fig. 4, the stator core 1 of the inner rotor type motor is composed of a plurality of laminated laminated steel plates, and the inner peripheral side faces the center side, and a large number of magnetic pole teeth 2a are formed. ~ 2i (tooth). Armature grooves 3a to 3i of the winding coil 4 are formed between the magnetic pole teeth 2a to 2i, and the surfaces of the armature grooves 3a to 3i are insulated by an insulator (not shown). . Generally, in order to collectively wind the φ coil 4 around the magnetic pole teeth 2a to 2i of the stator core 1, the nozzles (none of which are shown in the drawing) of the winding device are inserted into the armature slots 3a to 3i, one by one. Each of the magnetic pole teeth 2 a to 2i is moved to the surface-wound coil 4. That is to say, for one magnetic pole tooth, it is generally carried out: the coil winding start-the electromagnetic coil wire is cut off-the nozzle moves, and the next magnetic pole tooth winding starts. However, when each of the magnetic pole teeth 2 a to 2 i —'one by one 'winding wire 圏 4' is used, the working efficiency is poor. Therefore, for example, Patent Document 1 (Japanese Patent Publication No. 7_8 5 6 3 1) discloses that a coil is wound around a U-phase, a V-phase, and a W-phase corresponding to a 3-phase brushless motor without cutting the coil. Method of magnetic pole teeth of each phase. This makes it possible to shorten the winding work and the wiring work of the coil. -5-200531405 (2) Another method of shortening the working time, for example, in Patent Document 2, there are three nozzles that use armature grooves of three magnetic pole teeth arranged in parallel on a stator core that is unfolded in a straight line. Coiled in the form of three magnetic pole teeth. However, the aforementioned conventional examples have the following problems. That is, the motor described in Patent Document 1 is based on the premise that the coils of each phase are connected in series (serial) for Y-type wiring. When Y-wiring is to be performed in parallel (parallel), the connection process needs several times. The winding operation, winding start and winding ® must be completed with processing time and processing labor for the transition line. The electric motor described in Patent Document 2 (Japanese Patent Laid-Open No. 9- 1 9 1 5 8 8), for example, uses a thick coil as a stator core of a high-output motor such as a compressor, and the tensile strength of the coil It is necessary to increase the holding strength of the nozzles. It is difficult to increase the holding strength of the three nozzles at the same time. In addition, this patent document 2 is also the same as patent document 1 and discloses a method of parallel connection. [Summary of the Invention] Therefore, the present invention has been made in order to solve the aforementioned problems, and an object thereof is to manufacture a motor using the aforementioned electromagnetic coil as a Y-type connection after winding a plurality of magnetic pole teeth formed on a stator core and winding the electromagnetic coil. In order to shorten the coil winding and wiring work time. In order to achieve the foregoing object, the present invention has the following features. First of all, in a method for manufacturing a motor having the above-mentioned electromagnetic coil as a Y-shaped wiring after winding the electromagnetic coil with most of the magnetic pole teeth formed on the stator core, -6- 200531405 (3) is characterized in that the electromagnetic is not cut off in the middle One side of the coil is sequentially moved from the wound magnetic pole teeth toward the adjacent one of the magnetic pole teeth until the winding ends, and the coil is continuously wound, and a part of the crossing line between the magnetic pole teeth is cut off and formed. At the same time as the input terminal, connect the remaining wires to form a neutral point. The cutting point of the electromagnetic coil is set at a position of 1.5P (P is the pitch angle of the magnetic pole teeth) from the magnetic pole teeth of the winding start or winding bundle. The points are set at 2P intervals. In addition, the neutral point refers to a position from the magnetic pole teeth at the beginning or end of the winding by 0.5P (P is the pitch angle of the magnetic pole teeth) as the initial neutral point, and thereafter, for the initial neutral point, Set at intervals. According to this, the input coils are formed by cutting off the electric coils pulled out on one end side of the stator core, and connecting the electromagnetic coils pulled out on the other side to form a neutral point. This not only makes it easier. After wiring, the post-processing after wiring is also simple. It is characterized in that when the magnetic pole tooth at the beginning or end of winding is the first tooth, the cutting point is formed between the 2kth (k is a positive integer magnetic pole tooth and the 2k + 1th magnetic pole tooth). The circuitous transition line; the former neutral point is formed by connecting the circuitous transition lines between the 2k-1 magnetic pole teeth and the 2k magnetic pole teeth to each other. It is characterized by winding the aforementioned winding When the magnetic pole tooth at the beginning or the end of winding is the first tooth, the aforementioned cut-off point is formed at the transition line No. 2k-1 (k is a circuitous arrangement between the positive integer magnetic pole tooth and the 2k magnetic pole tooth; The transition junction is the 2P magnetic wire industry design) described in the configuration) in 200531405 (4) The nature point is the transition line between the 2k magnetic pole teeth and the 2k + 1 magnetic pole teeth alternately arranged between each other The connection is formed. According to this, regardless of the number of magnetic pole teeth, by setting a cut-off point and a neutral point at a position that satisfies this condition, the wiring operation can be easily performed. Its characteristic is that the stator core system can be arranged in a straight line Each magnetic pole tooth is unfolded in a state, and in the expanded state, the electromagnetic coil system I is sequentially and continuously wound from the magnetic pole tooth on one side to the magnetic pole tooth on the other side. According to this, the electromagnetic coil can be wound while the stator core is deployed on a straight line, the winding time can be further shortened, and the thick assembling operation is also simple. It is characterized in that the number of teeth of the magnetic pole of the stator core stator is 3n (n is a positive integer). Based on this, if the motor has an armature slot that meets this condition, it can be applied to a wide variety of motors without changing the basic specifications. The input terminal portion is formed by cutting the transition line drawn from one end face side of the stator core, and the neutral φ point is connected by the other end face side of the stator core. The drawn transition lines are formed between each other. According to this, by separating the transition lines on the cutting point side and the neutral point side from the side of the stator core and arranging them in a circuitous manner, the wiring operation can be simpler and the working time can be shortened. The present invention also includes a motor made by the manufacturing method. That is, in the item 9 of the scope of the patent application, while the majority of the magnetic pole teeth formed on the stator core are wound with the electromagnetic coil, and the electromagnetic coil is formed by the Y-type wiring, the electromagnetic coil is formed by winding. The magnetic pole teeth are continuously moved from the adjacent magnetic pole teeth to the magnetic pole teeth at the end of winding. 8- 200531405 (5) The winding is performed. The winding is arranged in a detour between the magnetic pole teeth, and the winding starts. Or the transition line from 1 · 5 P (P is the magnetic pole tooth angle) from the end of winding of the magnetic pole teeth is set as the initial cut-off point. Later, for the initial cut-off point, the cut-off point is formed on the transition line at the interval of 2P. The transition line from 0 to 5 P (where P is the degree of the magnetic pole teeth) from the start or end of the magnetic pole teeth is set to the initial neutral point. After that, for the previous neutral point, the interval between 2P The transition line forms a neutral point. g Based on this, the Y-type wiring can be simplified by cutting or wiring in a specific place, which can greatly shorten the winding and wiring operations. [Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a model diagram showing a fixed winding structure of a motor according to an embodiment of the present invention. Figure 2 shows its winding state and circuit diagram. It should be noted that the same reference numerals are assigned to the same conventional examples as in the above-mentioned conventional examples, and a description thereof will be omitted. In addition, the mechanism of the present invention is limited to a γ-type connection in which electromagnetic coils are connected in parallel (parallel). Among the constituent elements constituting the motor, particularly the winding structure of the iron core, the present invention may have any other constituent elements such as the structure of the revolving bearing unit and the trailer, and the like may be added for illustration and explanation. Omitted. As shown in Fig. 1, the stator core 10. In this example, a plurality of sheets of electromagnetic steel sheets laminated by pressing are used to form a pitch in a cross section of a specific thickness. The former time is obtained from the pitch angle first and separately. state. The electric wires of the first sub-core have the same wiring shape as the stator or each, and it will be formed by the punched body-9- 200531405 (6), and its inner peripheral side faces the center and protrudes many magnetic pole teeth. 2 a to 2 i are so-called inner rotor types. In this example, the magnetic pole teeth 2 a to 2 i are provided with a specific pitch and 9 teeth are provided. Between the magnetic pole teeth 2a to 2i, armature grooves 3a to 3i for winding the electromagnetic coil 4 are provided in a total of nine places. The armature grooves 3a to 3i are formed in a fan shape whose volume increases as it goes from the inner peripheral side. In the present invention, the shapes and magnetic characteristics of the magnetic pole teeth 2a to 2i and the armature grooves 3a to 3i are arbitrary and can be freely changed according to the specifications. Therefore, a more detailed description thereof will be omitted. Each of the magnetic pole teeth 2a to 2i is covered with an insulating member (not shown) such as a synthetic resin, and the electromagnetic coil 4 is directly wound around the insulating member through the insulating member. In this example, the electromagnetic coil 4 is used as a compressor, and a thicker coil is used than the electromagnetic coil used in a general electric motor. The electromagnetic coil 4 is first wound around the initial magnetic pole teeth 2a from the winding start end 41, and is not cut in the middle, and is then wound around the adjacent magnetic pole teeth 2b. Similarly, the electromagnetic coil 4 is not cut in the clockwise direction, and while sequentially crossing the successive magnetic pole teeth 2c to 2h, it is wound to the final magnetic pole tooth 2i, and the winding end 42 is wound there. Pull out. In this example, when the winding direction of the electromagnetic coil 4 is set to the first magnetic pole tooth 2a as the first tooth, each magnetic pole tooth 2 d, 2 f, 2 h including the even number of the subsequent second magnetic pole tooth 2 b is The odd-numbered magnetic pole teeth 2c, 2e, 2g, and 2i including the first magnetic pole teeth 2a are wound in opposite directions, respectively. As shown in FIG. 1 and FIG. 2 (a), the transition lines 4 a to 4 i across the electromagnetic coil 4 between the magnetic pole teeth 2 a to 2 i are alternately arranged on the magnetic pole teeth 2 a to 2 i -10 -200531405 (7) rooms. In each of the transition lines 4a to 4i, the winding start end 41 and each of the transition lines 4b, 4d, 4f, and 4h are pulled out on one end surface of the stator core 10 (the paper surface on the body side in the first figure). The remaining winding end 42 and the transition wires 4a, 4c, 4e, and 4i are pulled out on the other side of the stator core 10 (the back side of the paper surface in the first figure). In Fig. 1, the winding start end 41 and the transition lines 4b, 4d, 4f, and 4h pulled out on the body side of the paper are shown by solid lines, and the winding is pulled out on the back side of the paper The end 42 and each of the transition lines 4a, 4c, 4e, 4g, and 4i are illustrated by two dotted lines. Each of the transition wires 4b, 4d, 4f, and 4h including the winding start end 41 of the electromagnetic coil 4 wound around the stator core 10 is cut off by specific cutoff points 43 to 46. By connecting these cut points to each of the U-phase, V-phase, and W-phase, the input terminal portions 47 to 49 of each phase shown in Fig. 2 (b) are formed. In this embodiment, the input terminal portion 47 is a U-phase, the input terminal portion 48 is a V-phase, and the input terminal portion 49 is a W-phase input terminal portion. The transition lines 4a, 4c, 4e, 4g, and 4i are provided. There are four connection portions 51 to 54 for forming a neutral point. In this embodiment, the connecting portions 51 to 54 are formed by conducting clips that sandwich each transition line 4 &, 4 (^, 46, 4§, 4 丨 to achieve conduction, and are not cut off. Two transition lines are installed across to ensure conduction. In this embodiment, the connection portion 51 is connected to the transition line 4a and the transition line 4c. The connection portion 52 is connected to the transition line 4c and the transition line 4e. The 53 series connects the transition line 4e and the transition line 4g, and the connection portion 54 connects the transition line 4g and the crossing line 11-200531405 (8) The crossing line 4i. According to this, first, the electromagnetic coil 4 is not cut off and it is blown at a stretch. After being wound around the stator core 10, the transition lines 4b, 4d, 4f, and 4h are cut at cutting points 43 to 46 to form input terminal portions 47 to 49. Then, the transition lines 4a and 4 are not cut. c, 4 e, 4 g, and 4 i to form a neutral point through the connecting portions 5 1 to 5 4, and the U-phase, V-phase, and W-phase shown in FIG. 2 (b) can be simply and shortly Each phase is Y-shaped (star connection). Next, a modification of the present invention will be described with reference to Figs. 3 (a) and (b). As shown in Fig. 3 (a), this stator core 60 series can The magnetic pole teeth 2a to 2i are arranged in a straight line and developed. That is, the magnetic pole teeth 2a to 2i are connected to each other through, for example, a connecting portion of a thin-plate hinge through a synthetic resin or the like, thereby interposing the thin-plate hinge. The magnetic pole teeth 2a to 2i become bendable with each other. In the unfolded state shown in FIG. 3 (a), the electromagnetic coil 4 is sequentially continued from the magnetic pole teeth 2a on one end toward the magnetic pole teeth 2i on the other end. The ground is wound around the stator core 60. In this embodiment, the magnetic coil 4 has even-numbered magnetic pole teeth 2b, 2d, 2f, 2h and odd-numbered magnetic pole teeth 2a, 2c, 2e, 2g, and 2i. It is wound in the opposite direction. According to this, when the stator core 60 is unfolded on a straight line, when the electromagnetic coil 4 is wound around each of the magnetic pole teeth 2a to 2i, the amount of movement of the nozzle can be reduced, so that it can be more In order to shorten the winding time, the armature grooves 3 a to 3 i are widened. Therefore, it is also possible to prevent nozzle accidents, etc. After the electromagnetic coil 4 is wound, the two ends of the stator core 60 are mutually connected. Connect it, bend it into a loop, and make it The engaging portions at both ends are fitted to each other at -12- 200531405 (9), and a ring-shaped stator core 60 as shown in Fig. 3 (b) can be obtained. After the same method as above, the cutting point is 43 to 46. Each of the transition lines 4b, 4d, 4f, and 4h is cut to form an input terminal portion, and then the transition lines 4a, 4c, 4e, 4g, and 4h are formed at the connection portions 5 1 to 5 4 For the neutral point, the U-phase, V-phase, and W-phase phases can be connected in parallel (parallel) for γ-type wiring (star wiring). In addition, in terms of the rotational symmetry of the motor, the transition line forming the aforementioned cut-off points 43 to 46 and the transition line forming the connection portion (neutral point) 5 1 to 54 are about to be cut off and neutral. Dots are formed in reverse, with the same effect. In this embodiment, although the number of magnetic pole teeth of the stator core 10 is 9 teeth, as long as the number of magnetic pole teeth of the stator is 3 n (n is a positive integer), the windings corresponding to the magnetic pole teeth of each phase Do parallel connection, these can correspond to all stator cores. A more ideal form is to satisfy the rotor armature slot number of 2n (n is a positive integer). In this case, when the magnetic pole tooth at the beginning of winding is regarded as the first tooth, and the magnetic pole tooth at the end of winding is regarded as the third η tooth (η is a positive integer), the cut-off point is formed at the 2kth (k is (Positive integer) The neutral point of the transition line between the magnetic pole teeth and the 2k + 1 magnetic pole teeth is formed at the transition line between the 2k-1 magnetic pole teeth and the 2k magnetic pole teeth. In this embodiment, the transition lines 4a, 4c, 4e, 4g, and 4i constituting the neutral point are each connected without being cut. Therefore, the place where the entire winding of the electromagnetic coil 4 is cut is only Each of the aforementioned cutting points 43 to 46. -13- 200531405 (10) Above, although the description is made with reference to the attached drawings, the applicant of the present invention who is involved in the assembly of scroll compressors is within the scope of various modifications or technical scopes that are in the scope of patent applications. .
