Abstract:
In an aspect of the present invention, a motor comprises an annular stator core including a plurality of teeth portions extending along a radial direction and a plurality of conductor-connected bodies each including a plurality of conductors connected to each other. The conductor connected bodies are wave-wound along a circumferential direction of the stator core in each slot between the plurality of teeth portions. The plurality of conductor-connected bodies are arrayed in layers arranged in a radial direction in the slot. Among the layers in which the conductor-connected bodies are arranged in the slot, the radially outermost one is referred to as an outermost layer and the radially innermost one is referred to as an innermost layer. Each conductor-connected body includes a first terminal portion and a second terminal portion as both end portions. At least one of the plurality of first terminal portions and the plurality of second terminal portions is drawn from the outermost layer of the slot toward one side in an axial direction. At least one of the plurality of first terminal portions and the plurality of second terminal portions is drawn from the innermost layer of the slot toward the one side in an axial direction.
