Abstract

The invention belongs to the technical field of fluid machinery, and relates to a motor embedded impeller type integral flow channel axial flow fan. The axial flow fan comprises a front air cylinder and machine base assembly, an impeller, a motor stator and a rotor assembly. The rotor assembly is arranged in the front air cylinder and machine base assembly and coaxial with the front air cylinder and machine base assembly, and the motor stator is arranged in the circumferential direction of the rotor assembly in a surrounding mode. The electromagnetic force of the motor stator directly drives the rotor assembly to rotate around the axial direction of the rotor assembly, the impeller is arranged at the top of the front air cylinder and machine base assembly and connected with the rotor assembly, and the outermost diameter of the impeller is smaller than the inner diameter of the front air cylinder and machine base assembly. The rotor assembly drives the impeller to rotate synchronously.The motor embedded impeller type integral flow channel axial flow fan reduces the axial size, effectively reduces the overall weight, relieves the vibration generated when a motor and the impeller rotate, and can meet various performance requirements of the fan in a limited space.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery, and relates to an axial flow fan with an integral flow path, in particular to a motor shaft extension part embedded in the impeller cavity, and at the same time realizes the integration of the front air guide tube of the fan and the motor frame structure. Impeller type integral channel axial flow fan. Background technique [0002] The structure of the traditional front guide axial flow fan is usually that the front guide tube is installed on the air inlet side of the impeller, and the motor is installed on the air outlet side of the impeller, that is, the motor is installed in the rear guide tube; or the impeller is connected to the air guide tube through the transmission shaft The belt pulley, gearbox and other transmission mechanisms are connected, and then connected with the motor drive shaft; the front guide tube of the traditional axial flow fan and the motor are generally independen...
