A stator includes a stator core and a coil wound around the stator core. The coil includes a basic coil segment including a pair of first legs and a first transition portion disposed on a first end surface side of the stator core, and a transition coil segment including a pair of second legs and a second transition portion. The second transition portion includes a pair of shoulders and a pair of second rising portions. An inclination angle of the second rising portion is larger than an angle of the shoulder with respect to a first end surface, so that the second transition portion is in contact with the first transition portion.

Stator, rotary electric machine, and work machine

A stator includes a stator core including a plurality of teeth and a plurality of slots, a coil wound around the plurality of slots, and a spacer disposed on an end portion in an axial direction of the stator core. The coil includes a plurality of coil segments, each including a bent portion and a pair of legs. The spacer includes a coil support portion that is disposed between an end portion of each of the teeth and the bent portion of the coil segment and that has a support surface. A distance from the end portion of each of the teeth to the support surface on an inner side in a radial direction of the stator core is longer than a distance from the end portion of each of the teeth to the support surface on an outer side in the radial direction of the stator core.
