The direct drive method to powering a sanitary belt is best. Traditional motorized pulleys embed a gear box and electric motor inside an oil filled shell, so they get hot. One Motion Direct Drive Powered Pulleys push the magnets around using electromagnetic force, do not have oil or gears, and do not get hot.
How is this possible? Efficiency. We push magnets around an external magnet ring at a very high conversion rate of electrical power to achieve mechanical motion. The heat left over dissipates easily through the metal shell and our Powered Pulleys do not get hot!
