Noise reduction and heat dissipation motor

Abstract

The invention provides a noise reduction and heat dissipation motor. The motor includes an inner shell body, an outer shell body and an end cover; the outer shell body is of a cylindrical structure with one open end, and the end cover is arranged at the open end of the outer shell body and connected with the outer shell body in a sealed mode; the inner shell body is hollow and is of a cylindricalstructure with two open ends, the inner shell body is arranged in the outer shell body, and the two ends of the inner shell body are coaxially arranged with the outer shell body separately; the two ends of the inner shell body abut against the outer shell body and the end cover respectively, a gap is reserved between the inner shell body and the outer shell body to form a noise reduction cavity, and the noise reduction cavity is internally provided with a noise absorbing sleeve sleeving the inner shell body; multiple annular noise absorbing cavities are axially formed in the noise absorbing sleeve at intervals, each annular noise absorbing cavity is filled with noise absorbing cotton, multiple noise absorbing hole rows are axially distributed on the inner shell body at intervals and correspond to the annular noise absorbing cavities in a one-to-one mode, and each noise absorbing hole row comprises multiple noise absorbing through holes communicated with the corresponding annular noiseabsorbing cavity. The noise reduction and heat dissipation motor is great in noise reduction effect, high in heat dissipation speed and longer in service life.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a noise-reducing and heat-dissipating motor. Background technique [0002] As an important component that converts electrical energy into mechanical motion, the motor has been widely used in various occasions. However, when the traditional motor is working, with the rotation of the rotor, the noise of the motor will be directly transmitted to the outer surface to form noise and cause environmental pollution, which will make people around the motor feel irritated and reduce work efficiency; and the existing motor cooling effect Generally, it is difficult to remove the hot air inside, so that the working parts in the motor are kept in a high-temperature environment for a long time, which seriously affects its service performance and practical life. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention propo...
