Look at the table the 1 hp motor takes will be 1.3 A at 440 Volts three-phase at the same time while using single-phase it takes only 3.8 Amps.
Does increasing horsepower increase ampere value?
Look at that, while increasing the horsepower rating the ampere value and motor size also will be increased.
How to calculate HP to amps?
Rearrange the formula of hp to amps for the three-phase line-to-line system P = I * √3 * V * PF* η / 746;
How to use the hp to amps calculator?
Let's say we want to find the current flow in an AC single phase motor. The engine's designed power is 1 hp, and it works with a voltage equal to 200 V. The engine's efficiency is 90%, while the power factor is 0.92. Let's work out the result step by step using the appropriate horsepower to amps formula:
How to convert power to watts?
A rule of thumb states that you should multiply the power in hp by 746 to get the power in watts. Here we are assuming you're using electrical horsepower (for mechanical horsepower, the factor is circa 745.7 ).
What does amps represent?
Similarly, the amps represent the amperage, which refers to the electric current measured in amperes. Whenever you face the challenge of converting horsepowers to amps, you are about to estimate the output current from a device with a well-defined power. Analogically, if you try to convert amps to hp, you should evaluate the power knowing ...
What does HP stand for in electrical?
Hp stands for the horsepower - the unit of, well, power. Similarly, the amps represent the amperage, which refers to the electric current measured in amperes.
What is the output current of Ohm's law?
According to Ohm's law, the output current I is a ratio of the power P and the output voltage V. However, it changes a bit in real-life applications, as any power engine works with a certain efficiency η. Knowing that we can write hp to amps formula for direct current (DC) as:

How many amps does a submersible pump draw?
1 HP submersible pump motor will draw a current of 3. 2 amperes if it is single phase motor at a voltage of 230 volts, and if it is a 3phase motor at a voltage of 440 volts, it will draw a current of 1.7 amperes, maximum. To simplify. divide the wattage by the voltage and you will get the accurate amps.
How many amps does a 1HP motor pull?
If a 1HP motor pulls more than, say, 8 amps, something is probably wrong. However, again, these numbers may vary drastically depending on the type of motor and the operating conditions. This answer is general.
How much electricity does a 1HP motor consume?
Including motor losses, a 1hp motor will consume about 2kw while delivering 1HP. Assuming electricity at $0.20/kWhr, that means 1 hour will cost $0.40.
How many amps does a submersible pump draw?
1 HP submersible pump motor will draw a current of 3. 2 amperes if it is single phase motor at a voltage of 230 volts, and if it is a 3phase motor at a voltage of 440 volts, it will draw a current of 1.7 amperes, maximum.
How many amps does a 220 volt motor draw?
It depends on the rating of the motor. A 220 volt motor will probably draw about 4 amps from a 220 volt supply. A 110 volt motor will probably draw around 8 amps from a 110 volt supply. A 220 volt motor may run but only slowly or with reduced capability on a 110 volt supply.
What amps are marginal?
6 amp MCB would be at marginal, hence choose 10 Amps MCB.
How much power does a 1.5 HP pump use?
A 1.5 HP pump consumes 746W * 1.5 = 1,119 W (nominally). Assuming it runs on 120VAC, that equates to 9.3A. However, all motors require surge current when they start up so your pump is most likely consuming more current at that time (could be 15A). Also, if the pump is dirty or under severe water load, it will consume more current until it pumps the chamber out.
How many watts is 1 HP?
One mechanical HP is defined as about 757.7 watts. So if the motor is putting out the full rated 1HP at 100% efficiency, the current usage would be
How much horsepower should a motor have?
For a 1 horsepower (hp) motor the load should typically be in the range 1/2 to 1 hp with maximum efficiency at 3/4 hp. A motor with a service factor can occasional be overloaded. Overloading will over time reduce motor efficiency.
What is motor efficiency?
A motor of a given rated horsepower is expected to deliver that quantity of mechanical power at the motor shaft. Be aware that the motor efficiency is not calculated in to the values for kW and amps below. Motor efficiency must be considered to avoid undersized power supply.
