Motor Efficiency: VFD_SMALL
Motor efficiency and power factor � NEMA MG 1 efficiency and power factor data at full, 75%, and 50% load for standard and premium efficiency motors by horsepower
| motor class | hp numeric | efficiency fl pct (%) | hp rating | notes |
|---|---|---|---|---|
| VFD_SMALL | 0.25 | 74 | 25% load | hp_numeric is load fraction (0.25/0.50/0.75/1.00); efficiency_fl_pct = drive efficiency at stated load; drive range 1-10 HP; 1HP namepoint; pronounced efficiency drop at light load |
| VFD_SMALL | 0.5 | 84 | 50% load | hp_numeric is load fraction (0.25/0.50/0.75/1.00); efficiency_fl_pct = drive efficiency at stated load; drive range 1-10 HP; 1HP namepoint |
| VFD_SMALL | 0.75 | 87 | 75% load | hp_numeric is load fraction (0.25/0.50/0.75/1.00); efficiency_fl_pct = drive efficiency at stated load; drive range 1-10 HP; 1HP namepoint |
