Nettet3. sep. 2014 · PF indicates how effectively an AC motor uses current to perform work (torque) and ranges from 0 to 100 (0 to 1). For example, assume that a 1-horsepower, 230-volt, single-phase motor is 100 percent efficient. If the motor power factor is 100 (1), which is impossible, the utility would have to supply just 3.24 amps (746 watts) for the … Nettet6. des. 2024 · A value of 90% of no-load current is recommended. A motor’s no-load-current is typically in the range 30 to 40% of its rated value. From a practical point of view, auto-excitation is most likely to occur when the motor power factor is relatively low, under 0.8, and installation power factor objective is high, above 0.95.
