How to calculate power of motor
WebTo 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 … WebHow to calculate torque from rpm and hp? The main methods of measuring torque are using RPM, which is revolutions per minute, and HP, horsepower. First Method. Torque = 63025 x Power (Measured in HP) / Speed (Measured in RPM) Second Method. Power (Measured in HP) = Torque x Speed (Measured in RPM) / 63025. Third Method.
