PURPOSE:To facilitate the insulating work between coils by reducing potential difference between two coils contained in the same slot. CONSTITUTION:Lead wirings of phase U are connected to the starting position of a coil U1 to become a reference, and lead wirings of phase V are connected to the starting position of a coil V1 which is isolated at an electric angle of 120 deg. from the coil U1. The lead wirings of phase W are connected to the starting position of a coil W1 which is isolated at an electric angle of 140 deg. from the coil U1. The coils U1-U3, V1-V3, W1-W3 as the first coil group of the respective phases are sequentially connected, and coils U4-W4, U5-W5 as the second coil group which are disposed between the coils U3-W3, the coils U1-W1 and the coils U2-W2 which are disposed at the final end of the first coil group are connected. Further, coils U6-W6, U7-W7 as the second coil group which are disposed between the coils U5-W5, U3-W3, U1-W1 are connected, and coils U8-W8, U9-W9 are the second coil group which are disposed between the coils U7-W7, the coils U2-W2 and U3-W3 are connected. |
