Abstract
A reduction in size and an improvement in cooling performance of a dynamo-electric machine are achieved. A stator of a dynamo-electric machine according to the present invention includes a plurality of segment coils surrounding a rotation axis, a stator core partially accommodating each of the segment coils, and an insulating coating covering at least certain portions of the segment coils protruding from the accommodating space of the stator core, in which the segment coils are arranged in a direction from the rotation axis to a radially outer side, and the volume of the insulating coating is larger on a radially outer side than on a side close to the rotation axis.
