The cast iron housing is one of the most important factors determining an electric motor's mechanical strength and service life. Especially in heavy-industry applications, the difference in housing material is reflected directly in performance.

What Sets the Cast Iron Housing Apart

Cast iron provides high mechanical strength, superior vibration damping and corrosion resistance. Thanks to its high thermal mass it distributes heat evenly and runs stably under demanding conditions. These properties make the motor durable against impact and sustained heavy loads.

Where Is It Preferred?

Crushers and stone-crushing plants, compressors, large pump and fan systems and continuous heavy-duty applications are built with cast-iron-housing motors. It ensures long life on sites with heavy dust, humidity and vibration.

Cast Iron at DRG Motor

DRG Motor uses high-quality cast iron housings on its motors from 0.55 kW upward; with IP55 protection and class F insulation they suit continuous operation.

Choosing the Right Housing

For heavy loads, impact and demanding field conditions, a cast iron housing is the safest choice; we can determine the right model for your application together.
