Abstract
Provided is an armature for a rotating electrical machine, which is capable of improving heat dissipation performance of an edgewise coil to enhance efficiency of the rotating electrical machine. The armature for a rotating electrical machine includes: a core including a yoke section and a tooth section that protrudes from the yoke section; an edgewise coil to be inserted onto the tooth section through intermediation of an insulating member, the edgewise coil being formed by winding a rectangular wire having a rectangular conductor cross-section through edgewise bending; and a heat transfer member filled into a gap between the tooth section and the edgewise coil. The armature has different gaps formed at two regions between the tooth section and a long side of the edgewise coil.
