That could either be a single-phase or three-phase power source. P = I V = I 2R = V 2 R P = I V = I 2 R = V 2 R Calculating Power Using the Table Method These electric power calculations can be easily managed using the table method by adding another row below the voltages, currents, and resistances, as shown in Table 1. We have to substitute the variables on our 3-phase current formula with these values to find the amperage:.
E = Voltage / I = Amps / PF = Power Factor / EFF = Efficiency / HP = Horsepower. P = I V = I 2R = V 2 R P = I V = I 2 R = V 2 R Calculating Power Using the Table Method These electric power calculations can be easily managed using the table method by . Calculation: kW = I x V x x pf I = kW / (V x x pf) I = 37 / ( x x ) I = (37 / ) x I = ampere (full load ampere) 2) Horse power (hp) to ampere (I) First we must convert from hp to kW using this formula: 1 Hp = kW After that use the formula kW to ampere.
V = Volts A = Amperes R = Ohms P = Watts PF = Power factor (Motor) Eff = Efficiency (Motor) HP = Horsepower BHP = Break File Size: 19KB.
NOTE: Direct Current formulae do not use (PF, 2, or ); Single phase formulas do not use (2 or ); Two phase-four wire formulas do not use (); Three phase formulas do not use (2). To meet those desired outputs, we must follow the power , voltage, and amperage requirements of our motor. The calculators below can be used to calculate electric motor amps, horsepower and 3-phase kVa. If your motor's rating plate does not indicate the required amperage to run your motor, this 3-phase motor amperage calculator can help you with that.
Table method with power included. That is, given we provide its necessary power requirements. I = ampere (full load ampere) 2) Horse power (hp) to ampere (I) First we must convert from hp to kW using this formula: 1 Hp = kW. After that use the .
Motor Formulas. There are lots of different types of motors, and one way to classify them is by the power source we use to power them. Motors are machines that convert electrical energy to rotational mechanical energy.
