Abstract
An example of a positioning apparatus has a base member configured to support a stator core, a positioning tool disposed on its upper surface, and a driving mechanism for driving it. The positioning tool has a first plate and a second plate. The first plate has an inner side ring and an annular plate body fixed to the upper surface thereof, and the second plate has an outer side ring and a plate body fixed to the upper surface thereof. Insertion holes each configured to accept insertion of one of distal end pairs are formed on the plate bodies, respectively, and positioning is performed by rotating these plate bodies in opposite directions. Positions of the distal end pairs are aligned in the radial direction without the positioning tool, and then the positioning tool is set.
