The motor calculations presented here apply to changing conditions of a blower motor when pulley adjustments are made. However, these calculations are useful wherever electric motors are used. These ...

Each motor branch circuit must be protected against short circuit and ground faults by an overcurrent device sized no greater than the percentages listed in Table 430.52. A branch-circuit ...

Teledyne LeCroy’s MDA8000 series of motor-drive analyzers performs three-phase power-analyzer static (steady-state) calculations, dynamic three-phase power and mechanical motor analysis, and ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

Compressor overheating is one of the industry's most serious field problems today. Compressor overheating is usually caused by high compression ratios. High compression ratios can be caused by a ...
