WebHow to calculate power factor. To calculate power factor, you need a power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA), and to calculate the ratio of kW/kVA. The power factor formula can be expressed in other ways: … WebMar 26, 2024 · Efficiency and Current Draw. When choosing an FPV drone motor, it’s important to consider motor efficiency, typically calculated by dividing thrust by power at 100% throttle, measured in grams per watt (g/w). A higher number indicates a more efficient motor. However, don’t just look at efficiency at the top end.
