A motor includes a control part assembly having an air inlet through which air is inlet, an air flow path configured to communicate with the air inlet, and a printed circuit board; and a motor part assembly having a stator configured to generate magnetic flux when a current is applied, a rotor structured to be rotated while interacting with the stator electromagnetically, a motor shaft provided to be rotated together with the rotor, and an impeller coupled to the motor shaft and provided to be rotated to generate air flow, and is configured to be detachably coupled to the control part assembly. Through the structure as such, the performance of the motor may be improved.
