ABSTRACT:
A method of and apparatus for inserting coils into slots formed in the stator core of a dynamoelectric machine such as an electric motor, with the stator core having open type slots each of which cooperates with blades of the apparatus for guiding the coil and a stripper for forcing the coil out of the blades. A closed space has a volume sufficient to avoid any disorder of coil wire layers when the coil is received by the closed space. After placing the coils in the closed spaces, the coils are pushed into the respective slots and, as desired, the coils are further compressed until the coil wires assume a non-circular cross-section. By so doing, it is possible to remarkably increase the space factor of each slot.
