Abstract
The objective is to provide motors that are properly molded. [Solution] The motor 1 comprises a stator 20, a substrate 30 supported by the stator 20, and a resin member 50 covering the stator 20. In the axial direction, the substrate 30 has a first surface 30F facing the stator 20 and a second surface 30S opposite to the first surface 30F. The first surface 30F of the substrate 30 is in contact with the resin member 50. The second surface 30S of the substrate 30 has an inner circumference 30i, an outer circumference 30o, and an intermediate portion 30m between the inner circumference 30i and the outer circumference 30o. The intermediate portion 30m is provided with at least one conductive pad 40 and has a recess 45 surrounding the pad 40. The radial end of the recess 45 is formed radially outward d from the inner circumference 30i and radially inward c from the outer circumference 30o.
