THREE-PHASE ROTATING ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To provide a three-phase rotating electric machine improved in insulating performance even if a multi-phase coil is inserted into a stator by an automatic coil insertion machine. SOLUTION: Inter-phase insulating paper 30 is composed of first and second slot insertions 32, 32' that are parallel with each other and inserted into slots of a stator, and first and second inter-phase insulators 34, 34' that are integrally formed to both ends of the first and the second slot insertions 32, 32'. Widths of the first and the second slot insertions 32, 32' are wider than the maximum value of the width of the slot into which each slot insertion is inserted, and furthermore, the first and the second slot insertions are folded so as to form V shapes at their cross sections.
