Heavy-duty machinery and plants consist of equipment that requires high torque and continuity, such as crushers, mills and large handling systems. The electric motors used in these applications must suit the most demanding conditions in terms of durability and power.

Heavy-Duty Conditions

High starting torque, continuous heavy load, dust and vibration are common features of heavy-duty applications. In these conditions a cast iron housing provides high mechanical strength and vibration damping.

Motor Selection Criteria

For heavy-duty motors, high torque, IP55 protection, class F insulation and the S1 continuous-duty regime matter. Power is usually in the high-kW segment (90–355 kW).

Typical Applications

Stone-crushing and screening plants, concrete batching plants, mining and aggregate processing lines, and large conveyors are built with heavy-duty motors.
