Abstract
Provided is a fluid pump including: first and second housings that are mutually coupled; a support, shaft that is fixed to the second housing; an impeller that is accommodated in the first housing to thus pump fluid; a stator that is fixed to the second housing; a first rotor that is placed inside the second housing, rotatably supported on the support shaft, and is placed facing one side of the stator; and a second rotor that is fixed to the impeller, rotatably supported on the support shaft, and is placed facing the other side of the stator. The fluid pump employs an axial type brushless direct-current (BLDC) motor as a drive motor for driving an impeller, to thus realize a slim structure, and is formed to have the stator of the motor buried in the housing, to thus improve waterproof performance of the motor.
