Abstract

A stator for use in a motor includes a stator core, an insulator, a coil, and a terminal pin. The stator core includes a core back having an annular shape and teeth. The insulator covers at least a portion of the stator core. The coil is defined by a conductive wire wound around the teeth via the insulator. The terminal pin extends axially upward from an upper surface of the insulator and is connected to an end portion of the conductive wire. The insulator includes an annular portion, first protruding portions, and second protruding portions. The annular portion covers at least a portion of the core back and is centered on the central axis. The plurality of first protruding portions cover at least a portion of each of the teeth and protrude radially outward from the annular portion.
