Cast Iron Body Motors

Cast Iron Body Electric Motors

Cast iron body motors are designed for demanding industrial conditions where mechanical durability and long life are the priority. A cast iron frame is far more resistant to impact, vibration, high temperature and dust/humidity than aluminium. The DRG Motor cast iron series is built to run reliably in heavy-duty applications.

Advantages of a Cast Iron Body

High durability: superior resistance to impact and vibration.
Long life: long service even in harsh conditions.
Heat dissipation: the motor runs cooler thanks to good thermal conduction.
Harsh environments: suitable for dust, humidity and outdoors.

Aluminium or Cast Iron?

An aluminium body is light and advantageous for small powers and portable uses. A cast iron body is far safer under heavy load, continuous operation and outdoor conditions. That is why cast iron is preferred in industrial and mining applications.

Where Are They Preferred?

Cast iron body motors are preferred in crusher and stone-crushing plants, mining and cement, heavy-duty pump/fan systems and cranes. Built in IE3/IE4/IE5 classes they combine durability with efficiency; for general use also see the industrial motors page.

DRG Motor Cast Iron Series

DRG Motor cast iron motors are made with high-quality casting and strict quality control, providing long life and uninterrupted operation. For a cast iron electric motor, explore our range and contact us for prices and technical documents.

Protection Class and Environment

For cast iron body motors running in dusty, humid and outdoor conditions, the right IP protection class is critical. The heat-conduction advantage of the cast iron structure keeps the motor cooler and safer even under heavy load, reducing failure risk and lowering total cost of ownership.
