between gearless drives and drives using a gear, and, if gear driven, between single and dual pinion configurations. Furthermore, a decision between fixed speed and variable speed drives must been taken. This selection process is of course plant specific and may be biased by customer preferences or company guidelines.
veyor drive. ABB has addressed this issue by eliminating the gearbox altogether, replacing it with robust, reliable control from variable speed drives running accurately performing, low speed motors. Gearless conveyor drives for high power operate with synchronous motors that run at low speed, 50-60 rpm. Gearless drives for medium and low
This paper proposes a novel low-cost control strategy of gearless traction permanent-magnet synchronous machines for direct-drive elevator applications. It can improve robustness of the weight-sensorless traction machine system installed with an ordinary incremental encoder. In order to improve the riding comfort for the passengers during brake releases, a novel starting …

Ringmotor of the Gearless Mill Drive (GMD) System. CYCLOCONVERTER Principle The Cycloconverter is a frequency changer which converts a poly-phase voltage with the frequency f1 into a single or poly-phase voltage with a different, lower frequency f2. On Gearless Mill Drives (GMD), the operational output frequency varies from 0.3 Hz up to about 6 Hz.
These have also been fitted with gearless drive systems. Siemens was responsible for the configuration, manufacturing and the supply of the electrical equipment of the grinding mills. The SAG mill was fitted with a gearless drive with a power rating of 24 MW and the ball mills were also fitted with gearless drive systems, each providing 16.4 MW.
Do more with less - go gearless. Mine operators are challenged with moving more material on conveyors that may cover distances in the tens of kilometers and ascend steep gradients.

May 25, 2011 - ABB commissioned a gearless mill drive (GMD) system that powers a 38-foot semiautogenous (SAG) mill at the Canadian Malartic gold mine, which is owned by Osisko Mining Corporation. Engineering, delivery and commissioning of the complete 19 megawatt GMD system are worth more than $20 million.
drive concepts. When it comes to drive sizes exceeding 3,500 kW per individual drive, there are no conventional electromechanical drives with electric motors and helical bevel gears. Gearless drives, like those that are state of the art for the mine hoists implemented in underground mining operations, allow the use of larger drive units and are
Two 28 MW gearless mill drive systems (GMDs) are operating in the mine's 40 foot SAG mills and four 16.5 MW GMDS are employed in 26 foot ball mills along with associated control systems. The six ABB Gearless Mill Drives have been installed since late last year and are all now in continuous operation; ABB team at Mina de Cobre in Panama
"Gearless mill drives are the 'workhorses' for grinding operations which are at the heart of any mine. The six ABB GMDs at the world class Cobre Panama project are extremely robust. As the ore extraction pace indicates they are maximizing throughput," said Rene Chacon, project manager at ABB for Cobre Panama.
