Power Factor- PF - three phase motors(0 - 1) RLA - "Running Load Amps"- current drawn during normal operation of electric motor. FLA - "Full Load Amps"- amount of current drawn when full-load torque and horsepower is reached for the motor. FLAis usually determined in laboratory tests. Note!- in the calculator above FLAis RLA + 25%. 1 hp = 0.745 kW

To figure out how many amps does a motor with certain kW power have, we have to rearrange this equation a bit. We get the 3-phase current formula like this: I (Amps) = P (kW) × 1,000 ÷ (V (Volts) × PF × 1.732) Using this power formula, we can, for example, do a 3-phase motor kW to amps calculation.

An operating three phase motor has voltages measured with a voltmeter on each phase of 453, 458, and 461 volts, amperage measured on each phase with an ammeter 

Hp to Amps calculation formula, DC, AC, 3 phase, Multiply the AC voltage by the motor efficiency, the power factor and the square root of 3. For example, if the motor is 220Vac, it has an efficiency of 80% and the power factor is 0.9, it must Multiply 220Vdc by 0.8 (80%) by 0.9 by √3 (square root of 3) to obtain 274,35 (220Vdcx0.8×0.9x

Electrical. Single & Three Phase Line kVA calculator is an online tool used in electrical engineering to measure the unknown quantity by two known quantities applied to the below formulas for single phase and three phase connection. To calculate kVA, you need to enter the known values of voltage and the current into the respective fields.

The resulting value is the amount of power, expressed in amps, required at the input side of phase converter. Here’s a simple example of the equation: You’re preparing to drive a three phase low-horsepower motor rated at 10 amps. Single phase to 3 phase power calculation input requirement = The square root of 3 (1.732) x 10 amps = 1.732 x

3 phase power in HP P (HP) = 0.00402 x I (A) x V (L-N) x pf While considering Line to line voltage, the three-phase power in HP will be 3 phase power P (HP) = 0.00232 x I (A) x V (L-L) x pf Example: Find the HP rating of the 3 phase induction motor. The following nameplate details are line to line voltage 415 V, 1.3 Amps & 0.86 power factor.

Assuming that the motor is running under full load and at 415V: 1 hp = 745.7 watts Power

Power in KW = 1.5 *746/1000 = 1.119. Note 1 HP = 746W. Therefore, I =. (1.119 * 1000)/ (240 * 0.8*0.85) = 6.86 Amps. Suppose we have a 3-phase, 10KW, AC Motor with 415V, line voltage 3-phase power source and power factor 0.8 and efficiency of 88%, the full load current will be arrived at by manipulating the power formula for 3-phase motors to

AC single phase watts to amps calculation. The phase current I in amps (A) is equal to the power P in watts (W), divided by the power factor PF times the RMS voltage V in volts (V): Induction motor no load: 0.35: Resistive oven: 1: Synchronous motor: 0.9: Watts to amps table (120V) Power (W) Voltage (V) Current (A) 10 watts: 120 volts: 0.

Basically, we just multiply amp by volts. The '1,000' factor is there to convert from W
