How Many Amps Does A 600hp 460 Volt Motor Draw
With this calculator you can convert online from Hp to Amps or Amperes to Hp automatically, easily, chop-chop and free.
For ease we explain how to convert from Hp to Amps in merely 3 stride, that the formula is used for the calculation, some examples and a tabular array with the chief conversions of Hp to Amps.
Nosotros besides show the most common power factors in addition to efficiency values.
Hp to Amps calculation formula, DC, Air-conditioning, 3 stage, 2 stage, one phase:
- IDC=Direct current.
- IAC1Ø=Current/Ampere 1 phase.
- IAC2Ø=Electric current/Ampere 2 phase.
- IAC3Ø=Electric current/Ampere three phase.
- H.P=Horsepower.
- 5DC=Voltage direct electric current.
- FiveL-North=Voltage line to neutral.
- 5L-L=Voltage line to line.
- Due eastf=Efficiency.
- P.F=Ability cistron.
How to convert Hp to Amp AC 3 phases in merely three footstep:
Step 1:
Multiply Hp (Horsepower) by 746. Case, if you have 100 hp multiply by 746 and you get 74600. (100Hpx746 = 74600).
Step two:
Multiply the AC voltage by the motor efficiency, the power gene and the foursquare root of 3. For example, if the motor is 220Vac, information technology has an efficiency of 80% and the ability factor is 0.nine, it must Multiply 220Vdc by 0.viii (80%) by 0.9 by √iii (foursquare root of iii) to obtain 274,35 (220Vdcx0.8×0.9x√three = 274,35).
Footstep 3:
Finally carve up pace i and step 2. For example, (100Hpx746) / (220Vdcx0.8×0.9x√3) = 271,9Amps.

How to convert Hp to Amp DC in merely 3 stride:
Step 1:
Multiply Hp (Horsepower) past 746. Instance, if yous have 100 hp multiply past 746 and you get 74600. (100Hpx746 = 74600).
Step two:
Multiply the DC voltage by the efficiency of the motor. For case, if the motor is 220Vdc and has an efficiency of 80%, multiply 220Vdc by 0.8 (lxxx%) to go 176. (220Vdcx0.8=176)
Step 3:
Finally divide step 1 and stride 2. For example, (100Hpx746) / (220Vdcx0.8) = 423,86Amps.
Examples of hp to amp conversions:
Instance 1:
A mine dredger has a power of 80Hp, Ac, 4160V (L-L), 3 stage, with an efficiency of 84% (0.84) and a power factor of 0.8. How much amperage does this machine take?
Rta: // The first thing to do is multiply the Hp by 746, then you lot must divide the previous outcome between the multiplication of the voltage line line, the efficiency, the root of three and the power factor, giving as a result: 12.33 Amps . (80Hpx746) / (4160Vacx0.84 × 0.8x√iii)
Example 2:
An air conditioning system has a power of 5.4Hp, three phase, with a voltage line line of 220 Volts, an efficiency of 0.88 and a power gene of 0.9, how much amperage does this equipment take ?.
Rta: // You must multiply 5.4Hp by 746 and then dissever the effect by multiplying the rest of the variables, as shown beneath: (5.4Hpx746) / (220Vacx0.88 × 0.9x√3) = 13, 35 Amps.
Example 3:
An industrial blender of 50hp, bifasica, has a line-neutral voltage of 277 Volts, with an efficiency of xc% (0.ix) and a power factor of 0.viii, which will exist the amperage of the blender ?.
Rta: // It's simple yous merely have to enter the previous values in the calculator and it will easily give you lot the result that is: 46.76 Amps.

The information in this nautical chart was derived from Table 430-148 & 430-150 of the NEC and Tabular array l.1 of UL standard 508A. The voltages listed are rated motor voltages. The currents listed shall be permitted for organization voltage ranges of 110-120, 220-240, 380-415, 440-480 and 550-600 volts.
The full-load electric current values are for motors running at usual speeds and motors with normal torque characteristics. Motors congenital for peculiarly low speeds or high torques may have higher full-load currents, and multi-speed motors will have full-load currents varying with speed. In these cases, the nameplate current ratings shall be used.
Caution: The actual motor amps may be higher or lower than the average values listed in a higher place. For more reliable motor protection, utilise the bodily motor electric current as listed on the motor nameplate. Use this table as a guide only.

| 5 – 9 | 84.0 |
| ten – xix | 85.5 |
| 20 – 49 | 88.5 |

one) NEMA Design B, Single Speed 1200, 1800, 3600 RPM. Open up Drip Proof (ODP) or Totally Enclosed Fan Cooled (TEFC) motors 1 hp and larger that operate more 500 hours per yr.
How to employ the Hp to Ampere computer:
The first thing you take to practice is enter the Hp you want to convert, then you must choose the type of Air-conditioning or DC current, it is very important that once you cull the voltage blazon, exist aware of what the table asks for on the left side;then enter the number of phases, this option merely applies to the AC current, and then y'all must enter the efficiency.
Keep entering the voltage,at this point information technology is very important that you verify what is the voltage requested by the computer (line-line voltage or line-neutral voltage), otherwise the issue may non exist correct, finally yous have to enter the cistron of ability, if y'all do not know the latter you tin can come across the most common values.
