摘要： A stator coil is configured of a first group of six turns of conductive wire, and a second group also of six turns, with the first group of six turns being wound on a spool, leaving a gap the same as the diameter of the conductive wire between winds. Upon completion of winding the first group, the winding is turned back, and the second group of six turns is wound in the gap, so as to be adjacent to the turns of the first group. The article is then inserted into a slot in a stator core of a stator, thereby configuring a stator coil. This provides for a rotating electrical machine and manufacturing method thereof with improved insulation resistivity regarding inverter surge voltage, and moreover high output can be obtained with a machine of comparable external dimensions with conventional machines.

摘要： A large peeling force due to heat occurs at the boundary between the insulation coating over the coil end and the coil conductor when the stator coil emits heat and reaches a high temperature due to the high output of the rotating electric machine that causes the insulation coating to peel from the conductor consequently causing insulation defects. A sloped surface is formed on the insulation coating so that the thickness of the tip of the insulation coating on the coil end has a shape having a slope that becomes gradually thinner towards the welded coupling section made by welding the conductor.
