Nettet19. aug. 2024 · The mechanical output power is divided by the electrical input power to determine a motor’s efficiency: \eta=\frac {P_m} {P_e} In which \eta is the efficiency of electric motor, P_m and P_e are mechanical output power and input electrical power, respectively, which can be determined by the following equations: P_e=IV. P_m=T\omega. Nettet30. jan. 2015 · The actual power can be determined by performing a load analysis on the facility. This involves making a survey of the power requirements over a period of time. ekW = pf x kVA bkW = ekW / eff + Fan Demand Where: kVA = kVA output of generator pf = power factor of connected load ekW = electrical power (electrical kW) bkW = engine …
