Stator, motor, and blower

A stator of a polyphase motor in which in-phase coils are connected in parallel, the stator comprising:

• an annular core back;
• a plurality of teeth extending radially from the core back and arranged circumferentially;
• a slot between an adjacent pair of the teeth;
• conducting wires respectively wound around the teeth to define the coils;
• and
• a first connector and a second connector to which a first end and a second end of each of the plurality of in-phase coils are connected, respectively;
• wherein
• each of the conducting wires includes one or two jumper wires disposed between each of the coils and the first connector or the second connector;
• and
• the one or two jumper wires of all of the plurality of in-phase coils of the conducting wires of each phase have an identical winding direction about a circumference of the annular core back from the first connector toward the second connector.
