Abstract

The invention discloses a motor which comprises a fixed impeller used for guiding air flow, and the fixed impeller comprises an impeller disc and at least two blades; the blades are spirally arrangedon the periphery of the impeller disc, and an air guide channel is limited between every two adjacent blades; the inner ends of the blades are fixedly connected with the periphery of the impeller disc, sealing parts are formed at the outer ends of the blades, and the sealing parts are in interference fit with a machine shell/fan cover of the motor. The motor has the beneficial effects that it is guaranteed that the fixed impeller and the air gathering cover or the machine shell are in an interference fit state, meanwhile, the fixed impeller is easy to assemble and not prone to being stuck or broken, the sealing effect is good, the surge problem in traditional clearance fit is solved, and the assembly problem in interference fit is also solved.

Description

technical field [0001] The invention relates to the technical field of motors. More specifically, the present invention relates to an electric machine. Background technique [0002] The fixed impellers of high-speed brushless motors used in existing vacuum cleaners are all plastic parts, which are mass-produced by injection molding, and the transfer relationship between the fixed impellers and the fan cover or casing is clearance fit or interference fit. When the transfer relationship is a clearance fit, the gap between the fixed impeller and the windshield or casing is likely to cause the motor to have the problem of airflow backflow surge in the state of a small air inlet. When the transfer relationship is an interference fit, it increases Difficult to assemble, interference extrusion may easily lead to blade deformation or blade damage. In view of this, it is necessary to develop a motor and a motor to solve the above problems. Contents of the invention [0003] Aimi...
