Summary:PURPOSE:To have a safe construction and to make it possible to replace bus side wire rings with neutral side wire rings within a short period of time by providing a bus side leader line and a neutral side leader line to the inside of a stator frame and replacing part of these leader lines. CONSTITUTION:A bus side wire ring of each wire ring is connected to a bus side leader line 7, and is pulled out from a stator frame 1 through a connection section 9 into an air duct to connect to phase separation bus bars U-W. A neutral side wire ring of each wire ring is connected to a neutral side leader line 8, and is pulled out from the stator frame 1 through a connection section 10 into the air duct to connect to phase separation bus bars X-Z. In this condition, when the bus side wire ring is replaced with the neutral side wire ring, the bus side leader line 7 and the neutral side leader line 8 are dismantled at the connection sections 9 and 10. Auxiliary leader lines 11 and 12 are connected between the bus side wire ring and the connection section 10, and between the neutral side wire ring and the connection section 9.
