Abstract
A rotational motor includes a stator formed by a core member including: a magnetic core portion extending in a radial direction of the rotational motor and formed into a fixed shape in every cross section thereof extending orthogonally relative to the radial direction, a coil wound around the magnetic core portion to form a plurality of layers and an engagement member engaging with the coil. A gap is generated between windings of the coil at a predetermined position when an uppermost layer winding portion of the coil is wound in series with a second layer winding portion from an outer side to an inner side of the uppermost layer winding portion in the radial direction. The coil is wound to fill the gap when a winding position of the coil is returned from an innermost side to the outer side of the uppermost layer winding portion in the radial direction.
