Premium-efficiency motors also... ◊ Become less heated by harmonics ◊ Are more tolerant of phase unbalance and improper supply voltage ◊ Reduce distribution losses (as I 2 ) via all these loss reduction mechanisms ◊ Reduce cooling and air-handling loads in conditioned space ◊ Altogether ~18 benefits, not one—but paid for only once!
Savings depend on other improvements too ◊ <strong>Efficiency</strong> and motor life depend on… reducing voltage unbalance and harmonics improving shaft alignment and lubrication practice reducing overhung loads (sideways pulls) on the shaft that can cut bearing life by at least 5- to 10-fold, e.g. in belt-drive fans improving housekeeping—not siting motors in the sun or next to steam pipes, not smothering them beneath multiple coats of paint, etc.
