When selecting an electric motor, the choice between an aluminum housing and a cast iron housing is made by the application's load, the need for portability and the operating environment. Both materials offer different advantages.

When Is an Aluminum Housing Suitable?

Aluminum is light, conducts heat quickly and is easy to handle. It is advantageous in low-to-medium power pumps, fans and light machine drives, and in applications that are frequently removed or moved.

When Is a Cast Iron Housing Suitable?

Cast iron is superior under heavy loads, impact, vibration and demanding field conditions. It ensures long life in crushers, compressors and continuous heavy-duty applications.

Comparison and Decision

Aluminum is the right choice when light weight and cost are priorities; cast iron when durability and continuous heavy load are priorities. Both housings suit continuous operation with IP55 protection and class F insulation.
