Stator and motor

A stator used in a motor, the stator comprising:

• a stator core including an annular core back centered on a center axis and a plurality of teeth extending from the core back toward a radial inside;
• a plurality of pins including a conductive working portion extending in an axial direction in a slot between the teeth;
• and
• a plurality of bus bars electrically connected to the plurality of pins,
• wherein in each of the slots, the working portions are disposed over a plurality of stages in a radial direction,
• the plurality of pins include
• a first pin including the two working portions disposed across the teeth,
• a second pin including the two working portions disposed across the teeth, and
• a third pin that includes the one working portion and is connected to the bus bar,
• each of the first pin and the second pin includes
• a crossing portion connecting the two working portions in a circumferential direction on one side in the axial direction, and
• a connection portion connected to another pin on the other side in the axial direction of the working portion,
• in the first pin, the two working portions are inserted into an identical stage or stages adjacent to each other in the radial direction,
• each of the working portions of the second pin is disposed in one of an outermost stage and an innermost stage of the slot,
• each of the working portions of the third pin is disposed in one or the other of the outermost stage and the innermost stage of the slot, and
• a number of the teeth straddled by the second pin is larger by two than a number of the teeth straddled by the first pin.
