Stator and suction motor comprising same

A suction motor, comprising:

• a stator having an annular shape and including:
• a plurality of element stators adjacently arranged, each element stator of the plurality of element stators including a teeth portion and a body portion disposed at one end of the teeth portion, and
• a plurality of connecting portions,
• wherein, for adjacent element stators of the plurality of element stators,
• a respective connecting portion of the plurality of connecting portions connects a first lateral side of a first body portion of a first element stator of the adjacent element stators and a second lateral side of a second body portion of a second element stator of the adjacent element stators, and,
• a recess is formed at a front end of the first lateral side or a front end of the second lateral side;
• a rotor rotatably disposed in the stator with the teeth portion of each element stator of the plurality of element stators protruding toward the rotor;
• a rotation shaft passing through a rotation axis of the rotor so as to be rotatable together with the rotor;
• and
• an impeller connected to the rotation shaft,
• wherein the first lateral side includes a contact protrusion protruding between the respective connecting portion and the front end of the first lateral side,
• the second lateral side includes a contact recess allowing the contact protrusion to be inserted into a position corresponding to the contact protrusion,
• a length of the contact protrusion protruding in a direction perpendicular to the first lateral side is longer than a length of the contact recess recessed in a direction perpendicular to the second lateral side, and
• when the respective connecting portion is bent such that the first lateral side and the second lateral side face each other, the contact protrusion is in contact with the contact recess such that the first lateral side is spaced apart from the second lateral side.
