BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor device and a method of manufacturing the same, and more particularly to a motor device having a special structure of a stator of a motor and a method of manufacturing the same. BACKGROUND OF THE INVENTION A prior art motor device 10, as shown in FIG. 主要, mainly includes a stator 101, a plurality of coils 102, and a rotor 103. A plurality of winding teeth 1011 are disposed in the stator 101, and each coil 102 is wound around each of the winding teeth 1011. The rotor 103 is disposed inside the stator 101 to generate an electromagnetic force when the coil 102 on the stator 101 is energized, and to rotate the rotor 103 to form a motor device; or to drive the rotor to rotate by external energy, and generate a voltage in the stator coil to form Generator device. However, since the space between the adjacent two winding teeth 1011 is too small, the winding of the coil 102 is quite inconvenient and affects the thickness of the winding 102 and the volume of the winding. Especially when winding a thick wire, the bobbin must be thickened, the cogging clearance must be large, and the space between the adjacent two winding teeth 1011 cannot be increased, but the wire occupation rate is reduced, due to the cogging clearance. Large, the torque can not be reduced, making the overall use efficiency drop, the above problems will cause design and manufacturing difficulties. In order to reduce the torque, another prior art motor (not shown) is provided with an un-wound small tooth between adjacent two winding teeth, thereby reducing the cogging gap and thus having a drop. The effect of turning torque and increasing the efficiency of motor operation. There is also a motor arrangement (not shown) having the characteristics of | 2P-N _S | = 2 (where P is the number of permanent pole pairs of the rotor and N _S is the number of teeth of the stator winding), and the stator is provided with N _s / Two large teeth and N _s /2 small teeth, and the coil is only wound around each large tooth, and the rotor is arranged inside the stator. Since the J3⁄4 motor can adjust the tooth arc of the large tooth to approach the magnetic arc, Therefore, a large magnetic flux linkage can be generated, thereby improving the overall efficiency. However, the two kinds of motors mentioned above are not easy to be automated in manufacturing, and it is necessary to wind the wire around the stator and then wind it onto the winding teeth, so that the winding tightness of the coil is low, and a high end-end resistance is generated. In addition, if the thick wire is wound, the larger cogging gap must be reserved first, so that the torque is increased, so the actual use still does not meet the requirements of the user. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention mainly provides a motor device and a manufacturing method thereof, which may be a motor or a generator, wherein the stator of the motor device is provided with a plurality of winding teeth and a coil. They are respectively disposed on the winding teeth, and positioning grooves are arranged between the adjacent two winding teeth, each positioning groove is provided with spacing teeth, and no coils are arranged on the spacing teeth, after the winding teeth are wound, Insert the spacer teeth into the positioning groove. Since the stator is disposed in the positioning groove after the winding of the winding tooth is completed, the winding space of the coil is larger than that of the prior art when the winding is wound, so that the stator is not subjected to the cogging when winding.

When the coil on the armature winding is energized, the armature winding and the permanent magnetic pole group mutually induce electromagnetic force to generate mutual linear motion (linear motor) When the permanent magnetic pole group is driven by an external force, an induced voltage is generated on the armature winding (the linear generator X is disposed in the positioning groove after the winding of the armature winding is completed after the winding of the winding tooth is completed) When winding, the winding space of each coil is relatively larger than that of the prior art, so as to prevent the winding from being hindered by the pitch of the cogging. Compared with a linear motor, the invention can not affect the overall rigidity. In this case, the volume of the coil winding is increased, so that the wire occupation ratio can be improved, the cogging effect can be reduced, and the overall use efficiency can be improved.

The spacing teeth 113 are adjacent to one end of the positioning slot 112, and a joint portion 1131 is further laterally protruded for stable coupling of the spacing teeth 113 and the positioning slots 112. Since the stator 11 is disposed in the positioning groove 112 after the winding teeth 111 are wound, the winding space of each coil 12 is relatively increased, so that the stator 11 is not subjected to the cogging when winding. The thick coil is more conveniently wrapped around the gap. Compared with the general motor, the motor device of the first embodiment of the present invention can increase the winding volume of the coil 12 without affecting the overall rigidity, thereby increasing the wire occupation rate, reducing the torque, and further improving the overall Use efficiency. In addition, referring to FIG. 1B , the shape of the joint portion 1131 may be a dovetail block. In this case, the shape of the positioning groove 112 corresponding to the joint portion 1131 is a dovetail groove.

The thick coil is more conveniently wrapped around the gap. Compared with the general motor, the motor device of the third embodiment of the present invention can increase the winding volume of the coil 32 without affecting the overall rigidity, thereby increasing the wire occupation rate, reducing the torque, and further Improve overall efficiency. In the third embodiment, as described in the foregoing embodiment, the shape of the joint portion 3131 may be a dovetail block. In this case, the shape of the positioning groove 312 corresponding to the joint portion 3131 is a dovetail groove.
