Abstract: A motor is formed by stacking a plurality of stator elements and does not need an insulator between the stator elements. A stator includes the plurality of stator elements. The stator element includes a plurality of claw poles formed along a circumferential direction of the stator element and a coil wound in the circumferential direction. The coils of mutually adjacent stator elements are wound in different directions. In the mutually adjacent stator elements, the claw poles of one of the stator elements and the claw poles of the other of the stator elements are opposite to each other and are arranged to have the same polarity.
