There is provided a three-phase flat coil having a disclike outer periphery of an insulating plate and an electrical conductor positioned radially on front and back sides of said insulating plate and having bent-over portions on outer and inner peripheries thereof. Said electrical conductors are the three-phase coil windings including a-phase, b-phase and c-phase windings each wound in a wave form in the same direction and terminating at output terminals on the outer periphery of said plate. The output terminals are located at substantially one point on the outer periphery of said plate. The ends of the b-phase winding at said output terminals are different in polarity from the ends of the a-phase and c-phase windings. Intersections of the said three-phase coil windings are collectively positioned at substantially one point on the outer periphery of said insulating plate. Said intersections are provided for in a bridging wiring member which three-dimensionally connects the respective a-phase, b-phase and c-phase coil windings. The bridging wiring member having the intersections is provided at substantially one point of the outer periphery of the insulating plate thereby rendering the manufacture and wiring arrangement much easier. Stacking said flat coils together is easily accomplished by removing the bridging wiring member from one coil and placing that coil on top of another coil with an insulating plate in between. The output terminals of the bottom coil can be directly connected to the correct winding in the coil above. All connections are located at the outer periphery of the disc coils.
