Abstract
A device may include a coil unit assembly that includes a first, second, and third coil unit annularly arranged. Further, may include a busbar provided on an outer peripheral surface of the coil unit assembly, wherein when a direction in which an axis of the stator extends is defined as an axial direction, a direction which is orthogonal to the axial direction and in which outer peripheral surface and inner peripheral surface of the stator face each other is a radial direction, and a direction along an outer periphery of the stator when viewed from the axial direction is a circumferential direction, wherein the coil units each include a split core that includes a tooth that extends in the radial direction, an insulator mounted to overlap at least the tooth of the split core, and a coil that includes a winding wound around the tooth of the split core with the insulator interposed therebetween.
