Can you not decide whether to use an aluminum casing motor or a cast iron casing motor? Let's now take a look at the differences between the two types of motors.

Aluminum casing motor:
The material used is aluminum. The advantages are lightweight, good heat dissipation performance, good thermal conductivity, can be die-cast, good plasticity, higher elongation rate than iron, low noise, good stability in operation. The disadvantages : low hardness. It is suitable for installation in places where little effort is required.
Cast iron casing motor:
The motor casing is mostly made of cast iron material. Its advantages are high hardness, strong resistance to external pressure, not easily deformed, and can be installed in places with heavy workload and relatively poor environment. The disadvantages are heavy weight, poor thermal conductivity, cannot be die-cast, poor plasticity performance, and lower elongation rate than aluminum. It generates loud noise and has less stability compared to aluminum.
The differences and pros and cons between aluminum shell motors and cast iron motors are far more than just the ones mentioned above. Through practical work and life, we can also discover more differences and advantages/disadvantages between them, in order to choose a motor that is more suitable for our own equipment use.
What are the advantages and disadvantages of motor aluminum casing and cast iron casing?
Aluminum-cased motors are generally used for stable DC motors with high operating speeds, installed in less demanding locations. Aluminum is soft, so compared to cast iron casings, aluminum casings are lighter in weight, have good thermal conductivity, can be die-cast, have good plasticity, higher elongation than iron, higher price, and lower hardness.
Electric Motors with a relatively high center height do not use aluminum casings because the mechanical strength of aluminum is insufficient.
Cast iron motors are more powerful and are installed in places where there is greater driving force and poorer environmental conditions. Their stability is not as good as that of aluminum. There are several considerations for using aluminum casings for small motors:
We know that in AC motors, the motor housing does not participate in the conduction of electrical circuits or magnetic circuits within the motor; therefore it does not affect the electrical performance of the motor but only affects its mechanical performance.
Is there a difference between an electric motor with an aluminum casing and one with a cast iron casing?
Electric Motors with a shaft height above 180-315 almost never have an aluminum casing due to their poor mechanical strength.
Electric Motors with a shaft height above 56-160 could be with aluminum casing .
Electric Motors with a shaft height ranging from approximately 80 to160 may have both cast iron casings and aluminum casings. These two materials should not have much impact on the overall performance of the motor.
The difference between using cast iron or aluminum for electric motor housings lies in:
Detail
Accuracy tolerance
Because the internal elements will definitely release a major feature that converts electrical energy into mechanical rotational motion, as well as electromagnetic fields. As a result, movement and input power should be maintained very specifically, therefore, each position of the part needs to be positioned very possibly. The gap between blades, bearings, stators, air gaps, windings, and electric motor housing made between them should be as small as possible.
Regarding no leakage, we consider this requirement from two aspects. One aspect is about bubbles in the electric motor housing. In this case, it should be a strict requirement. On the other hand, the gap after assembly needs to be extremely small to prevent any lubricating oil from flowing out of the sealed cylindrical tube.
The main purpose of using a motor is to obtain a continuous and stable supply of mechanical motion. In order to keep the entire motor stable, portable real estate cannot be missed. Lightweight aluminum is the best choice in this market. For mass production with normal demand, die casting solutions are the most cost-effective. First-class, small-scale manufacturing, lightweight aluminum extrusion and CNC processing, can truly radiate the surface area and show the best way of high-end top quality.
Wearable
When the motor is working, all the main components that generate power demand rotate upward, forcing the relevant supports of the components to continuously contact the interior of the real estate with mechanical power. Due to the long procedure, the touched face is conveniently worn. The electric motor housing surface is made of aluminum, very smooth, and the roughness is very small, electric motor housing can definitely reduce the conflict between the contact surfaces and prolong the service life.
How The Aluminum Electric Motor Covering Is Manufactured
Light Weight Aluminum Motor ShellDie Casting Process
The aluminum alloy is first examined, then a chemical structure analysis is executed using a spectrology device. Next, the alloy is thawed by heating it to a temperature of roughly 680ºC, and after that infused right into the mold and mildew in the die casting equipment. On cooling, the covering is removed as well as deburred using pneumatic devices. The shell is then fired blasted, machined and also hand worked to make certain a smooth and also finish with no burrs.
The shell is heated up by induction to expand the size and the windings are then decreased in; they are secured into location as the covering cools. Amtech makes certain that the inner size (6.286- 6.288) of the shell is purely based on specifications, since if the covering is oversized the motor will fail. We for that reason measure the size with respect to the four mounting holes of dimension 8.39 ~ 8.63.
Electric Motor Housing Applications
Water-cooled AC motors
Water-cooled DC Motors
Water-cooled Switched Reluctance Motors
Finally, the die cast motor covering is cleaned up by utilizing reducing representatives, acid and ultrasonic methods, and the piece is rinsed between each cleansing cycle. The electrical motor housing unit is then dried in an oven, as well as after a last assessment by the Quality assurance Division, is packed as well as sent to the consumer.
