A stator of a polyphase motor in which in-phase coils are connected in parallel includes an annular core back, teeth extending radially from the core back and arranged circumferentially, a slot between two adjacent teeth, conducting wires respectively wound around the teeth to define the coils, and first and second connectors to which ends of each of the in-phase coils are connected, respectively. The conducting wire includes one or two jumper wires between each coil and the first connector or the second connector, and at least one jumper wire extends in an identical circumferential direction from the first connector toward the second connector with respect to all the in-phase coils.
