This will be several numbers because the amps change as the load goes up. So once that is determined amps times volts equals watts. figure the average watts for the run time, then turn that into a 1000 watt Hour number. Then divide that into your electric rate per KWhr. And charge him $1.45 per hour (just joking on the amount it is probably less) JimN
None of this correct. AC motors must be measured in true watts, Google "power factor" or "Ac motor theory." the only time AC POWER (watts) is equall to I X E as it is in DC circuits is when you have a purely resistive load, such as an electric heater.
Some estimate of motor wattage use CAN indeed be had by figuring DC power (I X E) and then just applying a "blanket" power factor of 80%
