power, and harmonics Power factor. If the circuit is operating at 100 % efficiency (which rarely happens), then demand is also a measure of power. In reality, power (kW) is usually less than demand (kVA). The difference, kW/kVA, is called power factor (PF). Utilities often collect a penalty charge if PF falls below 0.95. Some

The first step is to determine the drive mechanism for your equipment. Some examples are direct rotation, a ball screw, a belt and pulley or a rack and pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient, etc. that are required for the load calculation:
B: Sine of angle of incline C: Center to center distance (inches) D: Diameter of drive pulley (inches) d: Diameter of tail pulley (inches) E: Effective tension (lbs.) E1: Slack side tension (lbs.) E2: Tight side tension (lbs.) F: Coefficient of friction (See Table #1) G1: Load per square ft. (lbs.) G2: Load per hour (lbs.) HP: Horsepower K: Drive Factor-see table #2
