The base is fixed in the outer frame through the first guide vane and the second guide vane and is used for setting a stator iron core, the base and the fan blades are coaxial, and the stator drives the rotor to rotate to drive the fan blades to rotate so as to carry out axial flow air supply.
In the noise reduction fan with the high and low guide vanes, the stator further comprises a coil holder, the coil holder is arranged on the periphery of the base, and the stator core is arranged on the coil holder. The stator iron core is stacked on the wire frame, when the stator iron core is electrified, a rotating magnetic field is generated to drive the rotor to rotate, and the rotor drives the fan blades to rotate to supply air.
The fan blades of the high-low guide vane noise reduction fan comprise a fan frame and blades integrally formed on the fan frame.
In the noise reduction fan with the high and low guide vanes, the rotor comprises the rotor core, the rotor core is arranged on the fan frame, and the fan frame is connected with the shaft core. When the stator iron core is electrified to generate a rotating magnetic field, the rotating magnetic field drives the rotor iron core to move, the rotor iron core is arranged on the fan frame, and the fan frame and the blades are driven to rotate to supply air when the rotor rotates.
The bearing is arranged in the base, and the shaft core rotates in the base through the bearing. The bearing supports the shaft core to rotate, so that when the rotor drives the fan blades to rotate, the fan blades stably rotate on the base.
The utility model discloses the beneficial effect who gains is: through the setting of height stator, break the periodicity of the rotatory air current of supplying air of flabellum, avoid forming the vortex sinuous flow, reduce the noise that the air current produced when the stator for the noise of whole fan reduces, has good noise reduction effect.
