The aluminium housing motor is known as a green product in the motor industry due to its low pollution and is favoured by more and more countries, especially in the more economically developed countries where aluminium housing motors have become quite popular.
What is the difference between the housing materials of the motors?
What are the requirements for the selection of aluminum motor housing materials?
What are the advantages of using 3D printing to produce motor housing?
The difference between a motor housing being cast iron or aluminium is that
1, the motor housing is cast iron, durable, withstands knocks, high mechanical strength. Disadvantages: its weight is relatively heavy, easy to rust, heat dissipation is worse than aluminium.
2, the motor housing is aluminium, beautiful, not easy to rust, easy to process, good heat dissipation performance. However, the mechanical strength is poor and the cost is high, corresponding to a high price point.
3, in terms of electrical performance, whether the motor housing is cast iron or aluminium are the same.
Aluminum motor housing material selection Standard aluminum motor housing materials require appropriate cast aluminum alloy and heat treatment process to meet the application requirements. The choice of casting process also affects the quality and mechanical properties of the casting. The main considerations when selecting materials are as follows.
1. During operation, the stator is pressed into the inner casing and under load → alloy with high strength and high elongation
2. Dimensional stability in use → appropriate selection of heat-treated casting materials
3. Prevent surface contact corrosion, especially corrosion of the outer sealing surface of the housing → use corrosion-resistant alloys
4. Shielding against electromagnetic fields → Ensure electromagnetic compatibility (EMC) of the materials used
5. Corrosion resistance requirements, which are especially important for seals. If the motor housing is corroded, the motor may fail due to water seepage. AlSiMg alloys (such as AlSi7Mg0.3 or AlSi10Mg) have high corrosion resistance and meet the requirements of mechanical properties. Furthermore, since all aluminum casting alloys are paramagnetic, EMC requirements are easily met.
The advantage of 3D sand printing is the ability to design highly complex parts without having to prepare expensive molds from scratch. In addition, as additive manufacturing offers unique design possibilities, entirely new designs emerge. And for 3D printed sand mold applications, additive manufacturing allows end users to thoroughly inspect and extensively test newly designed components before manufacturing production molds, which can save a lot of time and money in up-front mold making.
For casting applications, molds made from sand are cost-effective and refractory for steel and aluminum casting. For this reason, sand casting has always been popular, especially in the automotive industry. Modern industrial 3D printing has opened up completely new possibilities for foundries to make motor housings, because with the help of 3D printing systems it is possible to manufacture highly complex cores.
