Motor shell for paint production

Technical Field

The invention relates to the technical field of sheet metal coating production equipment, in particular to a motor shell for coating production.

Background

Sheet metal is typically formed by plastically deforming a number of thin metal sheets by hand or die stamping into a desired shape and size, and may be further formed into more complex parts by welding or by a small amount of machining. The surface treatment is carried out on the workpiece after the procedures of bending, riveting and the like are finished, the treatment modes of the surfaces of different plates are different, the surface electroplating is generally carried out after cold plate processing, the spraying treatment is not carried out after the electroplating, the phosphating treatment is carried out, and the spraying treatment is carried out after the phosphating treatment.

The coating is a continuous film which is coated on the surface of an object to be protected or decorated and can form firm adhesion with the object to be coated, and is a viscous liquid which is prepared by taking resin, oil or emulsion as a main material, adding or not adding pigments and fillers, adding corresponding auxiliaries and using an organic solvent or water.

The coating needs to be stirred in the production process, and a motor is generally used for driving during stirring.

The motor is an electromagnetic device for realizing electric energy conversion or transmission according to an electromagnetic induction law. An electric machine generally includes a housing, and a stator and a rotor disposed within the housing.

The motor is unobstructed to be dispelled the heat through the radiating fin who distributes in the casing surface. However, since a gap with a small pitch is formed between the heat dissipating fins and the narrow gap is not easily cleaned, the gap is likely to receive and accumulate dust.
