Motor device

A motor device, comprising:

• a stator;
• and
• a rotor, rotating with respect to the stator,
• wherein the stator comprises:
• a stator body;
• teeth, provided on the stator body and protruding toward the rotor;
• an insulator, mounted to the teeth;
• and
• a coil, wrapped around the insulator,
• wherein the motor device comprises:
• a plurality of conductive members, provided on one side of the stator in an axial direction of the rotor, extending across the insulator toward a radial direction of the rotor, and electrically connected to end portions of the coil;
• an inner support wall and an outer support wall, provided on one side of the insulator in the axial direction of the rotor and supporting the coil, which are wrapped around the insulator, from inside and outside in the radial direction of the rotor;
• and
• a nozzle insertion recess, provided on the outer support wall, opening toward the inner support wall and toward the one side of the insulator in the axial direction of the rotor,
• wherein the nozzle insertion recess is configured between adjacent conductive members when the stator is viewed from one side in the axial direction for inserting a nozzle and receiving coating agent from the nozzle.
