Full-Load Current in Amperes Two-Phase Alternating-Current Motors (4 wire) The preceding calculations apply to induction type, squirrel-. The motor current calculator calculates the full load current of an AC induction motor. Motor voltage (V) Phase. 3 Phase, 1 Phase. Motor power rating (kW, hp). Equation 1 reveals: 469.7 x 37 x 0.763 x v3. 1000. Pi = = 22.9 kW. Page 5. 5. Nameplate full-load current value applies only at the rated motor voltage. Thus, For calculating full load current in a 3 phase system we have to use the formula W =root 3 ?VL ?IL ?cos teeta (power factor )now IL =W /1 . 732 ?VL ?P.f .MOTOR CURRENT. SINGLE PHASE MOTORS AC Motors - full load current tables (1450rpm approx.) (provided as a guide to the selection of suitable MEM control For three-phase, full load current for the resistive load is equal to the three-phase power divided by 1.732 times of voltage. Here power factor will be unity Full load current calculation for a 3-phase AC supply: · SkW: Is the rated power in kilowatt (kW) · VLL: Is the line-to-line (phase-to-phase) voltage in volts. This motor full-load amperage (FLA) calculator allows you to calculate the full-load current of the AC electric motor. Wide variations from these figures can arise, especially on single phase motors, and engineers should, whenever possible, determine the actual full load current.
