WebFull Load current calculation Single-phase Motor: Single-phase motor full load current I is equal to power P divided by the power factor times of line to neutral voltage. P = V * I * Cos pi. Full load current I = P / (V x Cos pi) Amps. V= Voltage +/- 10 % in Volts. I= Full load current in Amps. Cos pi = power factor. KW = output power in Watts WebStarting Current, sometimes abbreviated as I start in electrical engineering, is a measure or rating of how much current required for a single or three phase AC motor to get started. It's generally, four times of running …
