Summary:This motor comprises: a rotor which includes a shaft extending in the axial direction; a stator which encloses the radially outward side of the rotor, and which includes a coil configured by winding coil wires; a holder which is disposed above the stator in the axial direction, and which has a plurality of through-holes extending in the axial direction and through which the coil wires pass; and a substrate which is disposed above the holder in the axial direction, and on which electronic components are mounted. Each of the through holes has only coil wires of the same phase passed through, and the plurality of through-holes are mutually separated according to coil wire phase. Ce moteur comprend : un rotor qui comprend un arbre s'étendant dans la direction axiale ; un stator qui entoure le côté radialement vers l'extérieur du rotor, et qui comprend une bobine configurée par enroulement de fils de bobine ; un support qui est disposé au-dessus du stator dans la direction axiale, et qui a une pluralité de trous traversants s'étendant dans la direction axiale et à travers lesquels passent les fils de bobine ; et un substrat qui est disposé au-dessus du support dans la direction axiale, et sur lequel sont montés des composants électroniques. Chacun des trous traversants comporte uniquement des fils de bobine de la même phase qui passent à travers celui-ci, et la pluralité de trous traversants la phase de fil de bobine. モータは、軸方向に延びるシャフトを含むロータと、ロータの径方向外側を囲み、コイル線が巻回されて構成されるコイルを含むステータと、ステータの軸方向上側に配置され、コイル線を挿通するとともに軸方向に延びる複数の貫通孔を有するホルダと、ホルダの軸方向上側に配置され、電子部品が実装された基板と、を備え、複数の貫通孔のそれぞれには、コイル線のうち同相の複数のコイル線のみが挿通され、複数の貫通孔は、コイル線の相毎に互いに分離した孔である。
