摘要:
提供马达,其具备具有沿中心轴线延伸的轴的转子、与转子在径向上对置的定子、将轴支承为能够旋转的轴承、覆盖定子的一部分的绝缘部件以及与定子的下部在轴向上隔开间隙地配置的电路板,定子具备包括环状的铁芯背部和多个齿的定子铁芯和线圈,绝缘部件具备覆盖铁芯背部的铁芯背部包覆部、覆盖齿的齿包覆部以及从铁芯背部包覆部的轴向的下端部沿着中心轴线延伸并且保持轴承的保持部。
摘要(英):
A motor includes: a rotor that has a vertically extending shaft; a stator facing the rotor in a radial direction; a bearing that rotatably supports the shaft; an insulation member covering part of thestator; and a circuit board spaced from a lower part of the stator in an axial direction. The stator comprises a stator core including an annular core back and a plurality of teeth and a coil, wherein the insulation member includes: a core back covering portion that covers the core back; a tooth covering portion that covers the teeth; and a holding portion that extends from an axially lower end of the core back covering portion toward the central axis and holds the bearing.
