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

AC three phase kilowatts to amps calculation. Calculation with line to line voltage. The phase current I in amps (A) is equal to 1000 times the power P in 

How do you calculate motor current for a 3 phase and single phase motor? 3-phase motor amps calculation with power rating in kilowatt (kW): \(I=\displaystyle\frac{1000 \cdot P_{kW}}

AC three phase amps to watts calculation Calculation with line to line voltage. Induction motor full load: 0.85: Induction motor no load: 0.35: Resistive oven: 1: Synchronous motor: 0.9: Amps to watts table (120V) Current (A) Voltage (V) Power (W) 0.1 amps: 120 volts: 12 watts: 0.2 amps:

Three phase formulas do not use (2) * For three-wire, two phase circuits, the current in the common conductor is 1.41 times the current in either of the other two conductors.

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.

Jul 20,  · I have a pump with Diesel engine 1450 RPM, 160 KW, Soi wants to change the diesel engine by Electrical Motor 1450 RPM, 160 KW, 3 Ph, 380 Volts, 50 Hz, so I need to know how many Amp. I need for each one phase ( they write in the motor 280 Amp is this total for all 3 ph or 280 Amp for each one phase ) Cheers.

The formula. The formula for calculation of electric effect in an electric system is P = V x I. To calculate the Watt (P) one has to multiply Volt (V) with Ampere (I). This has been explained in more detail in our Watt's law article. For a 3-phase motor one also have to divide the square root of 3. The formula now looks like this: P= (VxI)x

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

Approximate full load amperage of three-phase motors Table 2 presents the approximate full load current of three-phase motors with approximately 1450 rpm and 

Three Phase AC Motor FLA (Amperes) = (P [HP] × 746) / (V × 1.732 × cos ϕ × η) Where: P [HP] , P [kW] = Motor power rating (HP or kW), V = Motor rated voltage (Volts), η = Motor efficiency in

Calculate the full load current of AC induction motors with this Free Online Motor 3-phase motor amps calculation with power rating in kilowatt (kW): 

Conversion Formula · 5 HP Motor single phase Amps = 5 * 746 / (E * %Efficiency * PF) · 5 HP Motor Three phase Amps = 5 * 746 / (E * %Efficiency * PF * 1.73) 

A 3 phase electric meter is essential for calculating the 3-phase motor amps calculation by heavy electrical appliances. It is recommended to use this energy meter only when your load requirement is more than 5 KW to 7 KW. For a load lower than this, a single-phase energy meter is sufficient and much more economically viable.

Rearrange the formula of hp to amps for the three-phase line-to-line system P = I * √3 * V * PF* η / 746; Apply the values (we can approximate the square root of 3 as 1.73 ), P = 0.5 * 1.73 * 100 * 0.8 * 95% / 746; The resulting power equals 0.088 hp; We can also rewrite the outcome using scientific notation, P = 8.8*10⁻² hp.

The formula states that power is equal to the square root of 3, power factor, voltage, and current. P = √3 * V * I * cosΦ. While. P : electrical three phase power. I : the current of the 3 phase load. V : phase to phase voltage of the power source. cosΦ : is the power factor of the load.
