One Motion products use magnetic, direct drive technology to power belt conveyors. Each shell rotates by magnets pushing against each other. This design eliminates the nooks and crannies caused by conventional motor / gearbox systems where food debris and bacteria is typically found. No energy is lost through gears. Instead, the magnets rotate the shell directly. This one transfer of energy improves efficiency by as much as 54%, which cuts down on production costs and dramatically improves GHG emissions. Direct Drive Power by Pushing Magnets Around.
