Stator, rotary electric machine, and work machine

A stator comprising:

• a stator core including a plurality of teeth and a plurality of slots;
• and
• a coil wound around the plurality of slots at a predetermined pitch,
• wherein the coil includes
• a basic coil segment including a pair of first legs that are inserted into a pair of first slots located apart from each other by a first interval in a circumferential direction of the stator core, and a first transition portion that connects the pair of first legs and is disposed on a side of a first end surface in an axial direction of the stator core, and
• a transition coil segment including a pair of second legs that are inserted into a pair of second slots located apart from each other in the circumferential direction by a second interval wider than the first interval, and a second transition portion that connects the pair of second legs and is disposed such that the first transition portion is located between the second transition portion and the first end surface in the axial direction,
• the first transition portion of the basic coil segment includes a pair of first rising portions that extend obliquely to be apart from the first end surface in the axial direction while the pair of first rising portions approach each other from the first legs in the circumferential direction,
• the second transition portion of the transition coil segment includes a pair of shoulders that extend from the second legs in a direction to approach each other, and a pair of second rising portions that extend obliquely to be apart from the first end surface in the axial direction while the pair of second rising portions approach each other from tips in an extending direction of the shoulders, and
• an inclination angle of the second rising portion with respect to the first end surface is larger than an angle of the shoulder with respect to the first end surface, so that the second transition portion is in contact with the first transition portion.
