Abstract: A motor may include a stator having coil groups of plural phases and a connector, the stator comprising a plurality of split stators. Each of the split stators may include a split core having an arc-shaped core back section and a tooth section, an insulator, a coil which has a lead-out line that is connected to the connector. The insulator may have a first void extending between a first inner wall and a first outer wall. The first inner wall may have a lead-in groove. The stator may have a support ring disposed on the upper side of the first void. The support ring may have a second void extending between a second inner wall and a second outer wall. A plurality of lead-out lines of different phases may respectively accommodated in the first void and the second void.
