Motor and method of manufacturing motor

A motor comprising:

• a rotor that is supported so as to be able to rotate around an axis of rotation;
• and
• a stator that is formed into a cylindrical shape and having coil groups of plural phases and a connector, the stator comprising a plurality of split stators,
• wherein each of the split stators comprises:
• a split core having an arc-shaped core back section configured to connect with an arc-shaped core back section of another split core and a tooth section which extends toward the inside in a radial direction from the core back section,
• an insulator which covers the tooth section and at least a portion of the core back section,
• a coil which has a lead-out line that is connected to the connector, and is wound around the tooth section with the insulator interposed therebetween, and
• wherein the insulator has, at a portion which covers an upper surface in an axial direction of the core back section, a first inner wall which extends in a circumferential direction, a first outer wall which is disposed further to the outside in the radial direction than the first inner wall and extends in the circumferential direction, and a first void which extends in the circumferential direction between the first inner wall and the first outer wall,
• the stator further has a support ring which is disposed on the upper side in the axial direction of the first void,
• the support ring has a bottom portion which extends in the circumferential direction, a second inner wall which extends in the circumferential direction on an upper surface in the axial direction of the bottom portion, a second outer wall which is disposed further to the outside in the radial direction than the second inner wall and extends in the circumferential direction, and a second void which extends in the circumferential direction between the second inner wall and the second outer wall,
• a plurality of lead-out lines of different phases is respectively accommodated in the first void and the second void, wherein the first void is filled with resin.
