【産業上の利用分野】本発明は電動機のステータに関す
るものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric motor stator.
【0002】[0002]
【従来の技術】近年、電動機は薄型化を求められてお
り、その要求を満たすために巻線方式としてトロイダル
巻線方式が多く採用されている。2. Description of the Related Art In recent years, electric motors have been required to be thin, and in order to meet the demand, a toroidal winding method has been widely adopted as a winding method.
【0003】以下に、従来のトロイダル巻線をほどこし
た電動機のステータについて説明する。The stator of a conventional motor having a toroidal winding will be described below.
【0004】図4は従来のトロイダル巻線をほどこした
電動機のステータを示す平面図である。図4において、
7はステータコア、8aは第1スロット、8bは第2ス
ロット、9は巻線である。FIG. 4 is a plan view showing a stator of an electric motor provided with a conventional toroidal winding. In FIG.
7 is a stator core, 8a is a first slot, 8b is a second slot, and 9 is a winding.
【0005】以上のような構成をもち、巻線9はステー
タコア7にトロイダル巻され第1スロット8aに入って
おり、巻線9は続けてとなりの第2スロット8bに入
り、ステータコア7にトロイダル巻されている。以下、
同様にとなりのスロットに巻線9が巻かれている。With the above construction, the winding 9 is toroidally wound around the stator core 7 and is in the first slot 8a, and the winding 9 is continuously in the next second slot 8b and is toroidally wound around the stator core 7. Has been done. Less than,
Similarly, the winding 9 is wound around the adjacent slot.

【発明が解決しようとする課題】しかしながら上記の構
成では、以下のような問題点を有している。However, the above configuration has the following problems.
【0007】ステータコア7に巻線9をトロイダル巻す
る際に、巻線9は第1スロット8aから第2スロット8
bまで連続した巻線であるため、第1スロット8aに巻
線を実施している時は、第2スロット8bには何ら巻線
9がほどこせない。すなわち、巻線9は1スロットずつ
しか巻くことができない。When the winding 9 is toroidally wound on the stator core 7, the winding 9 is wound from the first slot 8a to the second slot 8a.
Since the winding is continuous up to b, when the winding is carried out in the first slot 8a, the winding 9 is not spread over the second slot 8b. That is, the winding 9 can be wound only one slot at a time.
【0008】また、2スロット以上連続した巻線である
ため、スロット間の渡り線が必要になり不良の原因とな
る。Further, since the winding is continuous for two slots or more, a crossover wire between the slots is required, which causes a defect.
【0009】本発明は上記従来の技術の問題点を解決す
るもので、巻線効率が向上し不良率が低下する電動機の
ステータを提供することを目的とする。SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, and an object of the present invention is to provide a stator of an electric motor in which winding efficiency is improved and defective rate is reduced.
