How much current can a 3 HP motor take?
Full Load Current: Three Phase AC Motors
| Motor Horsepower | Motor Ampere | |
|---|---|---|
| 1 | 230V 460 V | 4.2 2.1 |
| 1-1/2 | 230V 460V | 6.0 3.0 |

What is full load current of a 3 phase motor?
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 for resistive loads. Full load current I, I =P.
How many amps does a 3 phase motor?
Here are the Full Load Amp (FLA) values for typical 230VAC and 480VAC 3 phase motors.
| Motor horsepower | Full load amps 230VAC | Full load amps 460VAC |
|---|---|---|
| 2 | 6 | 3.0 |
| 3 | 9 | 4.5 |
| 5 | 15 | 7.5 |
| 7.5 | 22 | 11 |
How do you calculate 3-phase current?
Three Phase Current – Calculation
- kW = kVA x pf.
- kVA = kW/pf.
- kVA = kW / power factor = 23/0.86 = 26.7 kVA (26700VA)
- Current = VA / voltage = 26700 / 230 = 116 A.
- VLL =√3 x VLN
- VLN = VLL / √3.
- kVA = kW / power factor = 12 / 0.86 = 13.9 kVA (13900 VA)
- Current = VA / voltage = 13900 / 230 = 60 A.
Is 3-phase current per phase or total?
If a three-phase supply is available, then the 24,000 watts are divided by 3, meaning that 8000 watts is being used per phase. Now the current per phase is also down to a third of what it would be with a single phase supply (about 30 amps per phase, rather than 100).
How do you check 3 phase motor?
Testing a single-phase motor will require some preparation. For starters,you will need to wear safety gear.
How to convert a 3 phase motor to single phase?

What is the formula for 3 phase electric motor?
phase 3 apparent power = 82 x 230 = 18,860 VA = 18.86 kVA Total three phase power = 18.4 + 16.1 + 18.86 = 53.36 kVA. Similarly given the power in each phase you could easily find the phase currents. If you also know the power factor you can convert between kVA and kW as shown earlier. Unbalanced Voltages
How to measure a 3 phase power current?
P = VICos (ϕ) A comparison between the methods of measuring power in a three-phase circuit is shown in the table below.
