Calculating Redrive Ratios
A three to one (3:1) re drive ratio means the motor's shaft will spin three times around for one full prop revolution. It is the ratio of pulley sizes.
Belt Machines
With belt drives the ratio is measured by dividing the large pulley's diameter by the small pulley's diameter. A 3 inch diameter small pulley and a 9 inch diameter large pulley has a 3:1 reduction ratio.
