PURPOSE:To facilitate the insulating work between coils by reducing the voltage difference between two coils contained in the same slot. CONSTITUTION:The lead wires out of phases are respectively connected to the starting position (No.1) of a coil U1 to become a reference, the starting position (No.21) of a coil V1 isolated in phase at 380 deg. of an electric angle from the coil U1 and the starting position (No.11) of a coil W1 isolated at 240 deg. of an electric angle from the coil U1. The coils U1, U2, U3 of the first coil group of the phase U are sequentially connected, and connected to the coil U4 of the second coil group formed of the coils U4, U5 adjacent to the coil U3 disposed at the final end. The coils U6-U9 of the second coil group are sequentially connected from the coil U5. The coils are similarly connected in the other phases V, W. Then, the terminals, X, Y, Z of the end coils U9, V9, W9 of the respective phases connected in series with each other for the respective phases are coupled in Y connection. |
