Hi, If the voltage, full load current and full load output power (kW) of a 3 phase induction motor are known, and the efficiency is assumed to be 90% (is this realistic), am I correct in thinking that the full load power factor can be approximated (due to assumed and not actual efficiency) as follows;(adsbygoogle = window.adsbygoogle || []).push({});

P.F. = Output Power/(√3 * V_{Line}*I_{Line}*Efficiency)

E.g. Is the approximate full load power factor obtained by the Full Load Output Power (Mechanical Watts) divided by the full load kVA * Efficiency?
