PURPOSE: To increase the occupancy ratio of coil in a slot and smoothly insert the coil into the slit by forming many wedges of a stator on a ring shaped core, positioning the wedges in a pigeon tail shaped cross section inside the slot and forming the edges of a guide jig at the both sides of the slot.
CONSTITUTION: A recessed portion 21 is formed at the both surfaces of a wedge 20 in a pigeon tail shaped cross section. An edge 23 formed at the both sides of a guide jig 22, is fitted in the recessed portion 21. In order to insert a coil 10 into a slot 2, a conductor is wound as ring shaped in advance and a coil unit formed into a shape having projections in a radial direction according to the number of poles, is put into the guide jig 22. In addition, the edge 23 is fitted in the recessed portion 21 and the pigeon tail shaped wedge 20 is put into the jig 22. In this condition, the inside of the coil unit and the wedge 20 are pushed by a coil pusher 11 and a wedge pusher 12 respectively.
