What is ODR?
ODR stands for Over-Design Ratio. In Design Flex you specify an input load and service factor which determines a Design Power by multiplying those values together. Design Flex then searches for drives that meet or exceed that design power. The over-design ratio is the belt’s Rated Load divided by that design power. If the ODR equals 1.00 then you have found a belt drive that is rated at your design power. If the ODR is less than 1 then the drive may be under-designed for the application. If it's over 1 then the drive is suitable for the application. Be careful though. If a drive is too over-designed it will reduce efficiency and can potentially damage other drive components.
