The stator assembling method includes: the step of disposing a guide to restrict circumferential movement of opening jigs inserted into slots; and the step of moving coils and the opening jigs together to a second side in a radial direction relative to a stator core while guiding the opening jigs such that circumferential movement of the opening jigs is restricted by the guide, thus inserting slot-housed portions into the slots.

Stator assembling method and stator assembling apparatus

A stator assembly method of assembling a stator that includes a stator core that includes a slot that has an opening that opens on one side in a radial direction, a coil that includes a slot-housed portion housed in the slot, and insulation disposed between the slot and the slot-housed portion, the method including disposing the insulation in the slot; opening a portion of the insulation on the one side in the radial direction by inserting a first guide jig into the insulation, which is disposed in the slot, along a center axis direction of the stator core, after disposing the insulation; and inserting the slot-housed portion into the slot via the opening by moving the coil and the first guide jig together toward the other side in the radial direction with respect to the stator core, after opening the portion of the insulation.
