What are the advantages of using aluminum for motor housings?

Aluminum shell motor, including the shell, panel, liner, bracket and other components, mainly from the role of protection of internal components. Shell body with high-quality aluminum alloy profiles, because the extension of aluminum performance, the proportion of small. But because of its aluminum processing technology requirements are high, the chassis, the end of the concentricity of the difference: the second aluminum shell non-magnetic field, the motor section of the magnetic circuit relative to the iron motor saturation, the use of electromagnetic noise with the current size changes The characteristics of mining state to change the voltage method to determine. The voltage quickly dropped to a certain limit.

It is generally recommended to replace this piece, and the ultra-high strength steel ribs, anti-side striker damage, will require replacement, for these structural parts, cutting must use pneumatic, electric cutting saw or plasma solitary cutting machine, welding must use inert Gas protection welding.

Second, the advantages of motor shell aluminum use

1, chemical stability, non-magnetic, can be repeated recycling, is a benign and recyclable metal materials. Elasticity coefficient is small, collision friction can not afford sparks, only the best performance in the car process.

2, there is a good extension of performance, with a lot of metal elements can be made of light alloy, material quality. Aluminum motor shell plasticity, good production, for the production of a very good advantage.

3, aluminum material without metal pollution, no toxicity, the surface oxide layer is not volatile metal. Aluminum housing has good thermal conductivity and electrical conductivity, outstanding performance in short distance transmission

    4, aluminum compared to other commonly used metal density is small, light weight, density is only 2.70 g / cm3, copper or iron 1/3. Using a hot, cold two kinds of process, a strong corrosion resistance.

Motor shell casting is not a very complete cylinder, the barrel of the raised objects and other ancillary structures are more cast parts of the wall thickness changes, casting cooling solidification of the stress will be relatively large, casting deformation tendency, before Can not be accurately predicted. The diameter of the straight head is 15 mm, the ellipse is more serious, and the diameter of the straight end is less than 1 mm by providing the annular cast bar at the straight end. The two large columns on the outside of the barrel body, the local formation of the "U" -shaped structure, where the deformation is also great, the distance between the two columns of the mold made when the scale, so that the size of the cast just in line with the nominal size; The thickness of the arc between the two pillars of the upper part of the shell casting is 12mm after the processing, 5 ~ 7mm after the actual processing, and 5mm is thickened by setting the amount of anti-deformation and the arc to the axis of the barrel. The problem.
