How to Calculate the Size of a Mine Hoisting System

RopesDrumsTypes of Hoisting-EnginesCalculation of The CylindersHaving settled the size of the useful load to be hoisted, the size of the rope must be determined. This must be strong enough to hoist the total load, including its own weight, and to withstand the starting-stresses due to picking up the load suddenly when the rope is slack. Experiments have shown that, in starting with six inches of slack rope, the stress in the rope is about double that due to picking up the load gently.Expressing these stresses in a formula, letK = stress in rope in pounds

Electric Motor Power Measurement and Analysis

The synchronous speed is the speed of the stator's magnetic field rotation, calculated as 120 times the line frequency divided by the number of poles in the motor. Synchronous speed is motor's theoretical maximum speed, but the rotor will always turn at a slightly slower rate than the synchronous speed due to losses, and this speed difference
