Abstract
A coil-forming wire material which can be efficiently arranged in slots of a motor core so as to down-size coil ends, thereby making the coil and a motor compact. The coil-forming wire material comprises a plurality of flexible thin wires. The thin wires are stuck at given portions such that they have a predetermined cross sectional shape. The stuck portions serve as rigid portions, i.e. coil sides. The coil-forming wire material also has flexible connecting portions where the wires are loose. The coil-forming wire material has the flexible connecting portions and the rigid portions which are arranged in an alternate manner. The flexible connecting portions serve as coil ends. The coil ends extend from the core with a small curvature due to the flexibility thereof.
