An aligning apparatus, which is provided for aligning coil segments to form an aligned coil, includes a cylindrical jig and a hook jig. The cylindrical jig has an outer cylinder to surround a radially outer periphery of the aligned coil and an inner cylinder to be surrounded by a radially inner periphery of the aligned coil. The hook jig has hooks arranged in a radial fashion and is rotatable relative to the cylindrical jig in a radial direction. The cylindrical jig further has an inner entrance provided in the inner cylinder, an outer entrance provided in the outer cylinder, and at least one of an inner guide wall extending from a front opening edge of the inner entrance radially inward and backward in the rotational direction and an outer guide wall extending from a front opening edge of the outer entrance radially outward and backward in the rotational direction.

Aligning apparatus and method of manufacturing aligned coil

An aligning apparatus is provided for aligning coil segments in an annular shape to form an aligned coil. Each of the coil segments has a pair of first and second leg portions. The aligning apparatus includes an outer jig and an inner jig. The outer jig has partitioning members arranged in a radial fashion. The partitioning members are spaced at such intervals as to allow each of the first leg portions of the coil segments to be inserted between one circumferentially-adjacent pair of the partitioning members. The inner jig has hole-forming members arranged radially inside the partitioning members of the outer jig. Each of the hole-forming members has formed therein a hole in which one of the second leg portions of the coil segments is to be inserted. Moreover, the hole-forming members are configured to be rotatable relative to the outer jig in a circumferential direction and radially movable.
