3 Phase AC Motor Starting & Running Current Calculator

Starting & Running current are the three important factors for the rating of AC induction motor. Starting 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 current. Similarly, Running Current, sometimes abbreviated as I_run is the current required for an AC induction motor to run freely with no-load after starting up. Similarly, Full-load Current, sometimes abbreviated as I_full-load is the current required for an AC induction motor to run with its maximum load or rated power. The measurement unit for current is Amperes often used as amps.
