Motor assembly, method of manufacturing the same and a cleaner having the same

A cleaner comprising:

• a main body of a cleaner;
• a suction head configured to vacuum substances from a surface to be cleaned into the main body of the cleaner;
• and
• a motor that is disposed inside the main body of the cleaner,
• wherein the motor comprises:
• a stator comprising:
• a plurality of teeth spaced apart in a predetermined interval in a circumferential direction, and
• a coil wound around the plurality of teeth;
• a rotor that is disposed inside the stator;
• and
• a cage that is disposed in at least one of a plurality of slots that are formed between the plurality of teeth,
• wherein the cage is configured to include a flow path to inject a bonding agent into the at least one of the plurality of slots and at least one leg fitting between extension portions of adjacent teeth of the plurality of teeth,
• wherein the cage comprises:
• a ring that covers one side in an axial direction of the plurality of teeth, and
• the at least one leg that is extendedly formed from the ring in an insertion direction of the cage, and
• wherein the at least one leg is inserted between at least two of the plurality of teeth that are adjacent to each other.

A method for manufacturing a motor including a rotor and a stator, the method comprising:

• winding a coil around a plurality of teeth that are spaced apart from each other in a predetermined interval in a circumferential direction;
• coupling at least one leg of a cage, that is fit on extension portions of adjacent teeth of the plurality of teeth, to the stator;
• and
• disposing a rotor configured to be rotatable inside of the stator,
• wherein the coupling of the cage to the stator comprises:
• injecting a bonding agent into at least one of a plurality of slots formed between the plurality of teeth through a flow path that is formed in the cage,
• wherein the cage comprises a ring that covers one side of an axial direction of the plurality of teeth and the at least one leg that is extendedly formed in an insertion direction of the cage from the ring,
• wherein the ring is bonded with one side in an axial direction of the plurality of teeth, and
• wherein the leg is bonded with another side of the plurality of teeth.
