90 kW (125 HP) 1500 rpm 380 V Three Phase Electric Motor - Cast Iron - DRG MOTOR, are built around a cast iron alloy body. The cast iron body provides high mechanical durability, vibration damping and superior heat dissipation, enabling long-lasting operation in demanding conditions.
Advantages of the Cast Iron Body
Cast iron is heavier and stiffer than aluminium. The extra mass absorbs vibration, keeps noise down and lets the frame take mechanical shock; it also carries heat out of the winding instead of holding it in.
Ideal Applications
Crushing and screening plants, pump stations, cranes and heavy machinery all run under continuous load with vibration coming back through the frame. That is where the weight of cast iron pays for itself.
Long Life and Low Maintenance
Wear develops more slowly in a rigid frame, so bearing service intervals stretch and total operating cost drops.
Testing Steps on the Production Line
Each unit goes through insulation resistance, vibration and balance measurement, efficiency and cosφ testing and a run under load before it is crated. Balance matters most in this class, because a 90 kW rotor at 1500 rpm punishes any residual unbalance.

Product Range and Lead Time
The İzmir warehouse holds 0.55 kW to 355 kW in IE3, IE4 and IE5 classes and ships nationwide. Heavy frames such as this 90 kW cast iron unit are palletised and dispatched on the same route. Contact points: electric motor dealers.
Frequently Asked Questions
Cast iron or aluminium: which one?
In heavy industry and high-vibration duty, cast iron lasts longer. Aluminium wins only where weight is the constraint. At 90 kW the answer is cast iron.
What power range do you cover?
The range covers 0.55 kW to 355 kW, and cast iron bodies dominate its upper half. Share the application and we come back with a model.
