Crusher & Stone Crushing Motors

Crusher and crushing-screening plants are among the most demanding applications for motors due to high torque, sudden load changes and dusty, harsh conditions. Durability and high starting torque are therefore critical in stone-crushing plants. DRG Motor offers heavy-duty motor solutions for crusher and aggregate applications.

Why Is This Application Special?

High starting torque: withstands loaded starts and sudden load increases.
Durable body: cast iron body motors against dust, vibration and impact.
Continuous operation: reliable performance over long shifts.
Protection class: high IP protection against dust and moisture.

Application Areas

Crusher motors are used in quarries, aggregate and stone pits, cement plants, mobile crushing-screening plants and recycling systems. These systems often require high powers (e.g. 110 kW, 160 kW, 250 kW); for the right power and speed see our power and speed options page.

Frequently Asked Questions

Why does a crusher motor need high torque? The crusher must be able to restart even while loaded, which requires high starting torque.
Which body should be preferred? In these dusty, high-vibration plants a cast iron body is the safest choice.

DRG Motor Crusher Solutions

DRG Motor offers highly durable, high-torque electric motors for stone-crushing and mining applications. Explore our range to choose the most suitable heavy-duty motor for your plant, and contact us for prices and technical documents.

High-Power Solutions

Crusher and crushing-screening plants often require high-power motors of 90 kW, 110 kW, 160 kW and above. Choosing the right starting method at these powers (star-delta or soft starter) protects the grid and extends the motor's life.

How many kW should a crusher motor be? It depends on the plant capacity and crusher type; generally heavy-duty motors with high starting torque in the 90–250 kW range are preferred.
