磁石を備えた回転子と、コイルをラジアルギャップ内に備えた固定子とから成り、かつ前記コイルを前記固定子の１つのティースに巻きつけた薄型ダイレクトドライブモータにおいて、前記固定子を構成するコアはオープニング形状の一体製造コアであり、かつ該オープニング距離はスロットピッチ幅からティース幅を差し引いた距離を有することにより真円度を限りなく０に近づけることが可能となることを特徴とする薄型ダイレクトドライブモータ。 A thin core direct drive motor comprising a rotor provided with a magnet and a stator provided with a coil in a radial gap , and the coil is wound around one tooth of the stator. Is an opening-shaped integrated manufacturing core, and the opening distance is a distance obtained by subtracting the teeth width from the slot pitch width, so that the roundness can be made as close to zero as possible. Drive motor. 前記固定子ティース内に空隙を設けたことを特徴とする請求項１記載の薄型ダイレクトドライブモータ。The thin direct drive motor according to claim 1, wherein a gap is provided in the stator teeth.
