The most common type of motor housing is sand casting, as well as resin sand and disappearing mould casting. motor housings are cast iron parts. Workshops, cupolas, models, blast cleaning machines, air drums, sand boxes, screw-type air pumps, etc. are required. The amount of investment varies considerably according to the scale of production.
What are the materials and processing technology of motor housing?
What are the reasons for using pig iron instead of cooked iron for motor housings?
What are the production characteristics of motor housings?
The motor housing material needs to choose the appropriate cast aluminum alloy and heat treatment process to meet the needs of use. And the choice of casting process will also affect the quality and mechanical properties of the casting. The main factors to consider when selecting materials are as follows:
Stator is pressed into inner casing and loaded during operation → alloy with high strength and elongation
Dimensional stability in use → suitable selection of heat-treated casting materials
Prevent surface contact corrosion, especially on the outer sealing surfaces of the housing → use corrosion-resistant alloys
Shielding of electromagnetic fields → Ensure electromagnetic compatibility of the materials used.
When developing the motor housing, it is not only necessary to consider whether the material meets the above performance requirements, but also to comprehensively consider the process selection and production and processing costs. The main processing technology of motor shell is die-casting and extruded profiles. Each has its own advantages and disadvantages. The profiled motor shell has stable performance and affordable cost, but it is only suitable for small-diameter motor shells with a single structure and function, and die-casting motor shells. It can meet the needs of large-diameter motor casings and integrated motor casings with complex structures, and has become the mainstream process form in the market.
The decision to prefer pig iron over wrought iron is primarily driven by performance considerations. Cooked iron, or wrought iron, is rarely utilized as a structural material due to its soft texture and low strength. On the other hand, pig iron, which contains carbon in the form of flaky graphite, is commonly referred to as gray iron. Gray iron possesses advantageous properties, such as excellent cutting, wear resistance, and casting abilities, owing to its soft graphite texture with a lubricating effect. However, it lacks sufficient tensile strength, rendering it unsuitable for forging. Nonetheless, it finds extensive applications in various castings, including machine tool beds, iron pipes, and more.
Ductile iron, another form of pig iron, contains carbon in the form of spherical graphite. Its mechanical properties significantly surpass those of gray iron and approach the characteristics of steel. Ductile iron exhibits exceptional casting, cutting, and wear resistance while offering a certain degree of flexibility. This makes it highly desirable for manufacturing high-level castings, such as crankshafts, gears, pistons, and various mechanical components.
