Tension force is calculated Static belt pull calculations also include static belt tension, which is added to counteract the centrifugal forces of the belt. Steel plate should be thick enough to carry all flux or result in the low pull force due to the magnetic saturation. Motor Speed. After running for a short time, this ratio is known to increase somewhat as the belt runs in and seats with the pulleys, reducing tension. The Belt Pull calculation does not include a centrifugal tension component. MASS TO MOVE (M) DIAMETER OF DRIVE DRUM (D): Watch on. Alternatively go to your railway engineering library (these are a part of the Railway Department, but can be accessed by engineers doing research on a specific problem). If a banded V -belt is used, refer to Elongation Method. Step 4. the conveyor as there is effective pull on both the upper and return sides in the form of belt tension. When the drive is stopped, the belt pull (force) is higher because these centrifugal forces are not present. Air gap between magnet and test plate.
