Abstract
In a motor stator, terminal wires of a coil are led out respectively from a feed-side and a neutral-side coil end. With three circumferentially adjacent first-, second-, and third-phase coils as one set, the leading end portion and intermediate portion of one of three terminal wires led out from the neutral side are connected to each of the remaining terminal wires. A structure wherein the first- and second-phase terminal wires are connected together in one position, and the second- and third-phase terminal wires are connected together in a different position from the one position, is adopted, thus compacting the size of one wire connection portion.
