PURPOSE:To obtain different motor characteristics, by constituting a coil strand with different kinds of metal coil strands. CONSTITUTION:In a coreless armature coil, the majority of axially extending core strands 1 is arranged circumferentially, cylinder-shaped, and fitted into one another, at least either of which has a circumferentially twisted internal layer coil body 2 and an external layer coil body 3. A connecting conductor 4 is provided to connect coil strands 1 one another diametrically facing both end faces of the internal layer coil body 2 and external layer coil body 3. The coil strands 1 are composed of different kinds of metal coil strands 1a and 1b. By setting the use ratio different kinds of metal coil strands, different motor characteristics can be obtained.
