る。2. Description of the Related Art In recent years, the size reduction and weight reduction of various motors have been dramatically advanced due to improvements in winding technology. Alignment and space factor are important factors in winding technology. Here, the degree of alignment is a degree of how closely a winding can be wound around a slot of a laminated core or a stator, and the winding can be wound in a tight and regular manner. On the other hand, the space factor is a ratio of the total cross-sectional area of the winding to the effective area of the slot. Therefore, if the degree of alignment is increased, the space factor can be improved naturally. In particular, it is known that when a rectangular wire is used as the winding wire, the space factor is improved as compared with the round wire. That is, as shown in FIG. 4, the slots 112 of the stator core 110 are
A bobbin 130 is provided in the. Then, the pair of bobbins 1 together with the teeth 111 of the stator core 110.
When the 30 is wound with the rectangular wire 120 having different aspect ratios, the rectangular wire 120 is wound in two or three steps and a plurality of steps in order to improve the space factor. At this time, the rectangular wire 1
In order that 20 can be wound most stably, the method of winding the flat wire in the horizontal direction from the beginning of winding, that is, the flat wire 120
The method of winding in the thickness direction is generally adopted.

低下していた。However, the rectangular wire 120 of the next stage cannot be wound on the rectangular wire 120 at the beginning of winding. That is, when the flat wire 120 is wound, the flat wire 120 at the beginning of winding becomes an obstacle,
The rectangular wire 120 must be wound at a position displaced from the rectangular wire 120 at the beginning of winding by the width of the rectangular wire 120. As a result, in the conventional winding method, the space factor of the rectangular wire 120 is reduced.

That is, since the effective area of the slot increases toward the outside of the stator core 10, the rectangular wire 20 increases toward the outside.
The number of windings can be increased. Therefore, the rectangular wire 20
By starting winding the bobbin from the inside of the bobbin 30, the space factor can be further improved.
