Aluminum motor is different from cast iron motor

If you can’t decide whether to use aluminum motor or cast iron motor, let’s take a look at the difference between the two materials.

Aluminum shell motor: the material used is aluminum, the advantages are light weight, good heat dissipation performance, good thermal conductivity, can die casting, plasticity can be good, elongation is higher than iron, low noise, good stability of action, the disadvantage is high price, low hardness, suitable device in the place without a lot of effort.

Cast iron motor: the motor shell is made of cast iron, which has the advantages of high hardness, high resistance to external pressure, easy deformation, low price, and can be installed in some places where driving force is large and the environment is poor.The disadvantage is that the weight is bulky, poor thermal conductivity, can not be die-casting, plasticity can not be good, elongation is lower than aluminum.Noise, stability is not as good as aluminum.

The difference between cast iron and aluminum motor housing is:
1. The motor shell is cast iron, which is durable, easy to knock, and has high mechanical strength.Disadvantages: its weight is relatively heavy, easy to rust, heat dissipation than aluminum.
2. The motor shell is aluminum, beautiful, not easy to rust, easy to process, good heat dissipation performance.But the mechanical strength is poor, the cost is also high, the corresponding price is also high.
