Abstract
A stator manufacturing apparatus includes an insertion tool inserted into a stator core, the insertion tool having a plurality of holding grooves formed on an outer periphery, the insertion tool being configured such that a pair of side portions of a stator coil are disposed in two of the holding grooves separated by a predetermined width; and a pressing tool having a plurality of plate-like pushers narrowed toward tips arranged on a pressing body in correspondence with the positions of the plurality of holding grooves of the insertion tool. The pressing tool is configured to push the pairs of side portions of the stator coils inserted in the holding grooves radially outwardly and insert the side portions into the corresponding slots. A recessed groove enabling grippers to be inserted when the stator coil is disposed using the grippers for gripping the pair of side portions is formed on the outer periphery of the insertion tool.
