Stator bars in Gearless Mill Drives

In an industry where downtime can result in millions of dollars in losses, ABB’s precision engineering and technological excellence offer an efficient and reliable solution. This allows mining operations to remain competitive, productive, and sustainable.

The grinding process is crucial in the mining industry, reducing mineral size for further processing. Unlike traditional mill drive systems, ABB’s Gearless Mill Drives (GMDs) eliminate the need for heavy mechanical components that require high maintenance. Instead, they directly power the mill through a magnetic field. This innovative design not only lowers maintenance costs but also enhances efficiency and reliability for mining companies.

ABB’s Ring Motors: unmatched power and performance

From its factory in Bilbao, ABB has manufactured over 110 ring motors operating in approximately 25 countries worldwide. With diameters of up to 20 meters, these motors are among the largest globally. Each unit is custom-designed to meet specific end-user needs, ensuring optimal performance and long service life.

Stator Bars: the key to efficiency

The true secret behind the high performance of GMDs lies in the stator bars. Along with their support structure, they form the stator, the fixed part of the ring motor that generates the magnetic field required to drive the motor and rotate the mill. Precision at every manufacturing stage, from material selection to assembly and final testing, is crucial. Any defect could compromise the efficiency and reliability of the system.

Enhancing reliability and efficiency in mining

Mining companies worldwide trust ABB’s GMDs to optimize production and ensure maximum reliability. In an industry where downtime can result in millions of dollars in losses, ABB’s precision engineering and technological excellence offer an efficient and reliable solution. This allows mining operations to remain competitive, productive, and sustainable.
