Dynamoelectric machine having a coolant path through a space provided in the flank of a winding

A dynamoelectric machine comprising:

• a winding formed of a bundle of conducting wires;
• a stator core including a slot in which the winding is disposed;
• and
• an insulating paper disposed between the stator core and the winding in the slot,
• wherein the conducting wires have a self-fusing property,
• the insulating paper has a foam layer,
• a coolant channel is formed between the conducting wires of the winding,
• the insulating paper is disposed to face a sidewall surface of the slot with the winding sandwiched therebetween,
• the insulating paper is also disposed on a wall surface of the slot on an outer diameter side of the stator core in a radial direction,
• a fixed member separate from the insulating paper is disposed in the slot on an inner diameter side of the stator core in the radial direction,
• the fixed member has a substantially inverse C shape in which a slot side opens and a stator core side is a flat surface, and
• the foam layer is not included from one end portion to another end portion of the fixed member.
