Abstract: A motor includes a shaft centered on a central axis that extends vertically, a bearing that supports the shaft, and a stator including a coil radially opposing an outer peripheral surface of the shaft. The shaft includes a magnetization pattern in which at least two or more poles of N and S poles are alternately arranged in a circumferential direction.
