As a rule of thumb, the estimated efficiency of many electric engines falls into the range of 70% – 90%. This means that a fully loaded 1 HP electric motor would consume anywhere from 0.746/0.7 – 0.746/0.9 kW, which translates to 0.829 – 1.066 kW per hour. Unfortunately, no hard number can be universally used for efficiency since
