Premium-efficiency motors aren’t just more efficient, but also… ◊ Have efficiency curves flatter across the load range, hence over integrated varying loads ◊ Typically have higher power factor (also flatter across the load range), reducing distribution losses and capacity needs ◊ Run cooler for lower resistive losses and longer life (each 10 C˚roughly doubles expected life) ◊ Cooler operation also extends grease life for longer lubrication intervals or less downtime
Premium-efficiency motors... ◊ Come with more durable bearings 3/4 of midsized motor failures are caused by bearing failures ◊ Automatically correct any iron damage from poor (most) past rewinds w/ stator burnout ovens Such damage wastes ~$1–3b/y in U.S. motors per GE (EASA notwithstanding) ◊ Are less susceptible to such iron damage (though it’s better to use the nondestructive Thumm method→) Avoided iron loss plus sizing effects typically about doubles the savings compared with efficiency ratings alone Stators after Dreisilker (Thumm) stripping method Dreisilker (Thumm) stripping equipment Photos courtesy Dreisilker Electric Motors, Inc.
