It’s likely from that figure that the motor is a 1400rpm model and the pulley set gives a reduction of 2.2:1. If the motor goes at 1400 rpm then the ratio will be 1400 / 808 = 1.73 to 1 With the belt on the big pulley, ie 135mm dia, the pulley size on the motor will have to be smaller by the ratio of the speeds, ie 1.73, so motor pulley = 135 / 1.73 = 78mm dia. They are available with loads of different bore sizes, so you need to find out the shaft size on the motor – it is often 14mm on smaller metric motors like this, but it sounds as though you’ve already selected a suitable motor.
