Abstract

See full text

A stationary portion of a motor includes a stator core including teeth, an insulator covering a surface of the stator core, a coil including a conductive wire, a housing, and a circuit board. The housing includes a cylindrical portion in which the stator core is fixed to the outer circumference thereof and a base portion extending from the cylindrical portion radially outward. The circuit board is disposed above the base portion and below the stator core, to which the conductive wire is electrically connected. The insulator includes a tubular portion covering the outer circumference of the cylindrical portion and a vertically deformable elastic portion protruding from the tubular portion radially outward. The circuit board is fixed to the upper surface of a seat portion of the base portion. The circuit board is in contact with the lower surface of the elastic portion radially inside the seat portion.
