The fan casing is provided with an air inlet and an air outlet. The impeller is right installed on one side, close to the air inlet, in the axial direction of the fan casing. The permanent magnet rotor is installed in the fin-shaped (for heat dissipation through a casing) stator core. A heat dissipation air duct is reserved between the motor rotor and the stator core. The stator core is segmental and is provided with a heat dissipation air duct. Fan blades and motor windings are respectively arranged on the two sides, on the motor rotor, of the stator core. Each fan blade is arranged between the stator core and the corresponding motor winding. Radial magnetic bearings are disposed on one side, far away from the stator core, of the motor windings. An axial flow fan is arranged between the motor windings and the radial magnetic bearings. One of the two radial magnetic bearings is installed in a position, far away from the air inlet, of the motor rotor. Two axial magnetic bearings are disposed on one side, far away from the stator core, of the radial magnetic bearing installed in a position far away from the air inlet. A suction disc type axial flow fan is arranged between the axial magnetic bearings.
