fpm to rpm conversion - Mechanical engineering general ...

Jun 17, 2005· Double the speed of the motor and you double the speed of the conveyor. The motor turns at 1800rpm. This is reduced through a gearbox to 60rpm. The circumference of the end drive is about 1 foot (4" X pi) and so a point on that moves through 60 feet per minute. As the belt moves at that speed it alos move at 60 feet per minute. "I love deadlines.

Calculating Conveyor Power for Bulk Handling | Rulmeca Corp

In imperial units, Te is expressed in pounds (lbs), and V is expressed in feet per minute (fpm). The product of the two factors is expressed in foot-pounds per minute (ft-lbs/min). Since one horsepower (HP) = 33,000 ft-lbs/min, required conveyor drive power may be expressed in HP as follows, (Te in lbs) x (V in fpm)/((33,000 ft-lbs/min)/HP) = HP

Motor Theory 101: Adjusting Frequency | VFDs.com

Nov 01, 2014· We also know from our formula that on Mars that same motor, using 230 V, at 30 Hz, also has a V/Hz of about 7.6. 460V/60Hz = 7.6. 230V/30Hz = 7.6. If you assume that a 30 Hz motor would have half the speed of a 60 Hz motor, then it would follow that a 60 Hz motor with an rpm of 1800 would have an rpm of 900 on Mars.
