<p>A flat wire (36) that forms a stator coil (16) has an insertion portion (22) that is inserted into a slot (14), and a coil end portion (30) that protrudes from an end portion of the stator coil (16). An insulating layer of an adjacent portion (38) that is adjacent to a flat wire (36) of a different phase at the coil end portion (30) is thicker than an insulating layer in another region. Setting the thickness of the insulating layer of each part according to the required insulation performance in this way makes it possible to make the overall insulating layer thinner, and improve the in-slot space factor of the stator coil while ensuring insulation performance.</p> |
