摘要:
A motor includes a stator with a stator core, an insulator, coils, and a terminal pin. The stator core includes an annular core back and teeth. The teeth extend radially outward from the core back and are arranged in the circumferential direction. The coil is defined by a conductive wire wound around a tooth via the insulator. The conductor is connected to the conductive wire and is connected to the circuit board. The insulator includes a cylindrical terminal holder located between adjacent ones of the teeth, extends in the axial direction, and accommodates the conductor. The core back includes a stator recess located between adjacent ones of the teeth and is recessed radially inward from the radially outer surface. The stator recess accommodates at least a portion of the terminal holder.
