Abstract

PURPOSE:To prevent increase production cost checking rare short-circuiting by inserting a metal material securely into a hole provided at the end of inner/outer double cylindrical armature coil piercing inner and outer coil strands to form a closed loop. CONSTITUTION:A sheet-like conductor bundle is wound in a spiral to make an inner layer coil while a similar sheet-like conductor bundle is wound in a reverse spiral on the circumference of the outer layer coil to form a double cylindrical armature coil. A through hole 11 is provided on the overlapping 10 of a coil strand 8 of the inner layer coil and a coil strand 9 of the outer layer coil at the end of the armature coil piercing both the coil strands 8 and 9. After an auxiliary metal connection material 12 is inserted into the through hole 11, a laser beam irradiates to connect both the coil strands 8 and 9. Thus, a closed loop is formed.
