The formula for sizing a pulley is: Engine Speed (RPM) = Pulley Diameter (Generator) Generator Speed 3600 RPM: Pulley Diameter (Engine) You want to operate an engine at 2400 RPM. Thus you will have less force to push the cutter through your material. HTP Timing Belts. For the Indirect Measurement, the total torque on the second pulley is zero since it is stationary. The amount of torque is a function of the pulley size, because the speed changes with pulley size. To calculate the inertial for a hollow, cylindrical pulley, substitute in equation 3:. This setting has a maximum speed of 1350 RPM. Using ringstands, pulleys, strings and hangers, set up apparatus as shown below. If you would like to find a value other than speed, fill in information for all the boxes and clear the value in box you would like an answer for. From this, we can calculate the torque exerted by the mass (a torque which our gearmotor must be able to exceed in order to lift the mass). The pulleys have frictionless axles but the string doesn't slip on their rims. We buy large quantities of manufacturer's surplus or excess stock. 10-27-99 Sections 8.
