According to an embodiment of the disclosure, a motor assembly may include a stator including a coil; a rotor accommodated inside the stator and configured to rotate; first and second housings coupled to first and second sides of the stator; an impeller disposed in a first direction of the first housing and configured to rotate together with the rotor by being coupled to one side of the rotor; a cover having an opening through which air is introduced by rotation of the impeller, and configured to protect the impeller; and a heat dissipation member surrounding at least a portion of an outer surface of the stator and configured to reduce heat generated in the motor assembly as the rotor rotates. Therefore, it is possible to minimize vibration caused by the rotation of the motor, thereby reduce noise, and lower heat generated inside the motor. Other various embodiments are possible.

Motor assembly

A cleaner according to the present disclosure comprises: a body; a suction head connected to one side of the body so as to suction foreign matter from a surface to be cleaned; and a motor assembly received in a motor case formed inside the body, so as to generate suction force, wherein: the motor assembly comprises a motor, an impeller disposed on one side of the motor and connected to the motor so as to introduce air, and a vibration isolator coupled to the other side of the motor and having a plurality of support protrusions protruding from the outer circumferential surface thereof; and the coupling between the plurality of support protrusions and the motor case causes the motor assembly to be spaced apart from the motor case.

Motor assembly and cleaner comprising same

Provided is a cleaning device including a vacuum cleaner including a dust collector into which dirt and dust is collected, a docking station connected to the dust collector and having a long axis extending in a first direction, and the docking station includes a docking part coupled to the dust collector to remove dirt and dust collected in the dust collector, a sucking device sucking up the dirt and dust and inside air in the dust collector docked with the docking part through the docking part, and a circulation duct arranged for the air sucked up by the sucking device to be circulated to the docking part.
