Description of the invention (1) [Field of invention] The present invention relates to a motor for a compressor with a three-phase star connection structure in which a plurality of magnetic pole teeth are directly wound on a stator; in particular, the neutrality from each wire is improved. Electric motor for compressor with wire connection structure. [Prior Art] Figs. 18 and 19 show a stator 1 of a general compressor motor to which the present invention is applied. The stator 1 includes a stator core 10 having a plurality of (in this case, 6 poles) magnetic pole teeth 12 arranged at intervals in the circumferential direction. To this, each of the magnetic pole teeth 1 2 ′ of the stator core 10 (isolated edge frame 3) is provided with a three-phase star-shaped coil 2. In this way, a three-phase star-connected compressor motor ' used to connect six neutral lines from a six-pole line to each other to form a neutral point. For example, Fig. 20 shows a connection diagram of a compressor motor used in the past to connect a total of 6 poles with 2 poles in each phase of each stator in parallel. In FIG. 20, a pair of (two-pole) coils 2 u, 2 v, and 2 w are provided for the three phases of U, V, and W in the radial direction of the stator 1, respectively, and each of the phases 1 is formed. The pair of coils 2 u, 2 v, and 2 w are connected in parallel, respectively. Then, six neutral wires 90 u to 90 w from these 6-pole coils 2 u to 2 w are connected to each other to form a three-phase star connection neutral point. In this case, the six neutral wires 90 u to 90 w are connected to each other by means such as welding, welding, and connection of guide wires. In addition, the structure of the 12 direct winding coils of each magnetic pole tooth is a circuit base for formation (please read the precautions on the back before filling this page) Applicable to China National Standard (CNS) A4 specification (210X297 mm) -4- 561668 A7 B7 V. Description of the invention (2) Connection of boards, etc. [Problems to be Solved by the Invention] The conventional compressor motor has the following problems. That is, in order to form a neutral point, a plurality of neutral lines must be connected to each other (in the case of the 6-pole type shown in FIG. 20, there are 6), so not only is the connection cumbersome, but it also increases the possibility of poor connection and causes reliability. problem. In addition, when connected by a circuit board, it also causes a problem in terms of cost. In order to solve such a problem, the present invention aims to use a fewer number of neutral wires to connect to each other to form a fixed connection structure at the midpoint, and it is easy to provide a stator connection that is superior in reliability. And low cost compressor motor. [Means for solving the problem] The first means is characterized in that it includes a stator and a rotor, and the stator has a plurality of magnetic pole teeth arranged at intervals in the circumferential direction, and the magnetic pole teeth are directly wound with three phases in a star connection. The coils of the three stators correspond to the neutral wires of any one-phase coil, and the compressor motors are connected to the neutral wires of the other two-phase coils in one place respectively. According to this first means, the neutral lines of the coils of any one phase are connected to the neutral lines of the coils of the other two phases, respectively, to form a three-phase star connection neutral point. That is, the neutral points are formed by connecting the two neutral lines to each other at the connecting portions of the two spaces in total. The second method is for the first method to be connected in parallel with each other (please read the precautions on the back before filling this page).

(Please read the precautions on the back before filling this page.) However, in the above embodiment, for a total of 6 poles 2 u ~ 2 w (and magnetic pole teeth 1 2) for 2 poles for each phase The case has been described, but basically, the present invention can also be applied to a case where coils 2 u to 2 w (and magnetic pole teeth 1 2) of 3 poles or more in total and 9 poles or more in each phase are provided. In addition, in the stator 1, the case where the yoke core 14 and the magnetic pole teeth 12 are integrated into one body type stator core 10 has been described, but the yoke core 14 and the magnetic pole teeth 12 are assembled differently. A divided stator core of the body is also possible. However, in this specification, "crimped terminal" refers to the terminal member that connects the wires with each other due to the large deformation of the terminal itself caused by riveting or the like; "crimped terminal" refers to the press-in through the wire, The terminal member connecting the wires to each other hardly follows the deformation of the terminal itself. Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs [Effects of Invention] According to the present invention, three or three-phase star-connected neutral points are formed by connecting two or three neutral lines to each other, so there are fewer than in the past The connection of the neutral lines to each other can form a neutral point. Therefore, it is possible to provide a low-cost compressor motor with easy connection to the stator 1 and excellent reliability.
