Field of the Invention The present invention relates to a motor stator structure, and more particularly, to connecting the other end of a ground wire having one end fixed to the outer peripheral surface of a ring-shaped stator to a printed circuit board. Accordingly, the present invention relates to a novel improvement for facilitating stator assembly and resin mold. 2. Description of the Related Art Conventionally, as a motor stator structure of this kind, in the case of a structure without resin molding, a ground terminal is directly screwed to a front lid or a rear lid or the like. Attach and ground. Further, in the case of the structure in which the resin mold is applied, a hole is formed in the end face of the ring-shaped stator, and a pin is attached to this hole to connect the ground wire. [0003] Since the conventional motor stator structure is configured as described above, there are the following problems. That is, in a structure in which no resin mold is applied, since the ground terminal is attached directly to the front lid and the rear lid with a screw, and then the ground wire is attached, it takes time to assemble, and it is difficult to automatically assemble. . In addition, in the structure where resin molding is performed, the ground wire must be connected after drilling holes in the end face of the stator, and then assembling, as in the case described above, it takes time and effort to assemble automatically. there were. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and in particular, the stator is assembled by connecting the other end of a ground wire having one end fixed to the outer peripheral surface of a ring-shaped stator to a printed circuit board. It is an object of the present invention to provide a motor stator structure that achieves simplification of resin molding and simplification of resin molding. [0005] A motor stator structure according to the present invention comprises a stator winding provided on each slot of an annular stator via an insulating cover, and a print provided on one end side of the insulating cover. A substrate is provided, and an earth wire having one end fixed to the outer peripheral surface of the ring-shaped stator is provided, and the other end of the earth wire is connected to the printed circuit board. A preferred embodiment of a motor stator structure according to the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, a reference numeral 1 denotes a ring-shaped stator having a ring shape as a whole and stacked in multiple layers. In each slot 2 of the ring-shaped stator 1, an insulating cover 4 formed in a ring shape is provided. U, V, and W-phase stator windings 3 are wound therethrough. A ring-shaped printed circuit board 5 is held between the claw 4a formed on the upper portion of the insulating cover 4 and the upper end 4b in a sandwiched state. An electronic circuit unit (not shown) and a print pattern 6 are formed. Outer peripheral surface 1 of the annular stator 1
a is one end 6a of a ground wire 6 made of a bendable conductive wire.
Is fixed by welding or spot welding, a conductive adhesive or the like, and the other end 6b of the ground wire 6 is connected to a ground pattern 6A (FIG. 2) of the printed circuit board 5. Therefore, the stator structure 10 constructed as shown in FIG. 1 can be entirely solidified by a well-known resin mold, or can be housed in a casing (not shown) without performing resin molding. You can also. The motor stator structure according to the present invention is configured as described above, so that the following effects can be obtained. That is, by connecting the other end of the ground wire, one end of which is fixed to the outer peripheral surface of the annular stator, to the printed circuit board, the earth connection of the annular stator can be achieved, and the assembly of the stator structure is greatly facilitated as compared with the related art. This can greatly contribute to the realization of assembly.
