Abstract
A rotating machinery is to be provided wherein coils can be wound round a stator core in a minimized state of connected parts. In a rotating machinery comprising a stator formed annularly and a rotor disposed rotatably on the inner periphery side of the stator, the stator comprises a stator core, the stator core having in the circumferential direction a plurality of slots each having a coil inserting portion on the inner periphery side, and coils wound by lap winding within the slots, at least the lap-wound winding portion of the coils in each slot being constituted by a continuous line and wound at a coil end so as to straddle the inner periphery side and the outer periphery side of the slot. According to this construction there is no increase in the number of connected parts even if the number of turns in the winding portion is increased.
