Abstract: An electric pump has a pump body, a pump magnet received in the pump body, an impeller received in the pump body and fixed to the pump magnet, and a disc type electric motor. The electric motor includes a stator, disc type coils fixed to a surface of the stator, a rotor rotatably positioned above the coils, and a circuit board electrically connected to the coils. The rotor has a rotor magnet positioned beneath the pump body and magnetically coupled to the pump magnet. When the coils are energized, an axial magnetic field is generated to drive the rotor and, through the magnetic coupling between the rotor magnet and the pump magnet, rotate the impeller.
