How do you calculate the full load of a 5 hp motor?
Full load current I, I =P. / 1.732 * V Amps.
How many amps does a 3 phase motor draw?
These are only intended to be guidelines and in all cases the full load amps of the motor nameplate should be used for final calculations….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 many watts does a 3/4 hp motor use?
Approximate Running Wattage
| Approximate Starting Wattage | Approximate Running Wattage | |
|---|---|---|
| Capacitor Start Induction Run 1/2 Horsepower | 1800 | 600 |
| Capacitor Start Induction Run 3/4 Horsepower | 2600 | 850 |
| Capacitor Start Induction Run 1 Horsepower | 3000 | 1000 |
| Capacitor Start Induction Run 1 1/2Horsepower | 4200 | 1600 |
How many watts does a 3 phase motor use?
Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts).
How heavy is a 5 hp motor?

What is the power output of a 3 phase 5-hp motor?
The 3 ph 5 HP motor, if operates at rated speed & draws rated current (mentioned on name plate) will require input of 5*746 = 3730 watt (1HP=746 watt) if efficiency of motor is assumed to be 100 \%. As most of the 3 phase motors used in industry are squirrel cage induction motors;
What is the wattage of a 5 hp motor?
So: the complete answer is “A 5 HP motor will require a wattage depending on its load.” And this is commonly between 350 watts and 3500 watts. Hello. The 3 ph 5 HP motor, if operates at rated speed & draws rated current (mentioned on name plate) will require input of 5*746 = 3730 watt (1HP=746 watt) if efficiency of motor is assumed to be 100 \%.
How do you convert hp to Watts on a motor?
Convert HP to watts by multiplying by 746. Then divide by the efficiency of the motor (available from the manufacturer) and that will be the electrical input watts. 3 phase or single phase doesn’t matter. One step further for 3 phase amps, then input kW/ (PF*kV*sq rt. 3) = amps.
How do you calculate 3 phase amps?
Mathematical equation: Three phase Amps = [HP * 746] / [E * \%age Efficiency * PF * 1.73] Example: Determine the current flowing through a three-phase, 2 HP, 400-volt motor having an efficiency rating of 93\% and a power factor of 0.9. Solution: Current = [2 * 746] / [400 * 0.93 * 0.9 * 1.732] = 2.57 Amps
