ABSTRACT:
A slot insulator guide used with a coil inserting apparatus for guiding a layer insulator and a wedge having different sizes from each other toward each slot of a stator core of a dynamoelectric machine. Both side faces of the guide include a first guide face for guiding a layer insulator and a second guide face for guiding the wedge. The first guide face is parallel to its axis while the second guide face is inclined. The first guide face has in its distal end an inclined face. Each guide face has a first engaging portion with which the end of a layer insulator is engaged. Each guide face further has in its distal end a second engaging portion with which the ends of the wedge are engaged. Each engaging portion extends toward the slot. A coil inserting apparatus with which the guides are used has a first and a second stepped portions. The pusher is abutted against the layer insulator and the wedge so that the layer insulator and the wedge are pushed. The first and second stepped portions are formed to be spaced from each other in a direction in which the layer insulator and the wedge are inserted in the slot.
