Abstract

The invention discloses a fan motor. The fan motor comprises a fixed seat, a rotor and a stator assembly, wherein the fixed seat comprises an annular shell, a rotor shaft and a connection part, wherein the rotor shaft is coaxially arranged in the annular shell, the connection part is connected to one end of the annular shell and one end of the rotor shaft and is used for fixing the rotor shaft, the rotor is coaxially arranged on the rotor shaft by a bearing, the stator assembly is arranged in a way encircling the periphery of the rotor and is fixed on an inner circumferential wall of the annular shell. By the fan motor, the problems that an existing fan motor is trouble to assemble and is poor in assembly accuracy, poor in running stability and large in running noise are solved. The invention also discloses an eccentric fan comprising the fan motor.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a fan motor and a centrifugal fan. Background technique [0002] The fan motor is the power mechanism of the fan, and its function is to provide power for the rotation of the fan blade. The existing fan motor generally includes a shell, a stator, a rotor and a rotor shaft. The bottom of the rotor shaft is riveted with a copper ring structure, and then a metal gasket is used to Cooperate with the bottom of the rotor shaft, which has the problems of troublesome assembly, poor assembly accuracy, difficulty in controlling the concentricity of the rotor shaft and the stator, and, due to the fit gap between the rotor shaft and the copper ring, the rotor shaft will swing radially during operation , the stability of operation is poor, and at the same time, the rotor shaft will move axially, and friction will be generated between the bottom end of the rotor shaft and the gasket, resulting in...
