Abstract:
The purpose of the present invention is to provide a motor that is appropriately molded. This motor (1) comprises a stator (20), a substrate (30) that is supported by the stator (20), and a resin member (50) that covers the stator (20). In the axial direction, the substrate (30) is provided with a first surface (30F) that faces the stator (20), and a second surface (30S) that is on the opposite side from 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) is provided with an inner circumferential portion (30i), an outer circumferential portion (30o), and a middle portion (30m) that is located between the inner circumferential portion (30i) and the outer circumferential portion (30o). At least one electrically conductive pad (40) is provided to the middle portion (30m), and a recess (45) that surrounds the pad (40) is formed in the middle portion (30m). A radial-direction end portion of the recess (45) is formed further toward the radially outer side (d) than the inner circumferential portion (30i) and further toward the radially inner side (c) than the outer circumferential portion (30o).
