How many watts does a 5hp electric motor use?

1 Horsepower is equal to 745.7 watts of electrical power, so in theory a 5HP motor operating at 100% efficiency will consume about 3.728kW of power.

How many watts does a 5 HP electric motor use?

It is easy to convert HP to watts based on the equivalence of 746 watts per horsepower and arrive at 5 HP = 3730 watts. However, in practice, motors seldom run at their nameplate current (FLA or Full Load Amperage).

What size generator do I need to run a 5 hp motor?

A true 5 hp on 220 volts would require 28 amps to run on 220 or 6160 watts so at a minimum I would think 20,000 watt generator.

How much current does a 5 hp motor draw?

AMP DRAW BASED ON HORSEPOWER

HP 1 Phase Amps 3 Phase Amps
115 volt 208 volt
5 56 16.7
7-1/2 80 24.2
10 100 30.8

How many watts does a 1 hp electric motor use?

One electric horsepower is equal to exactly 746 watts.

How many watts does a motor use?

W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts. Electricity costs are based on kilowatts (kW), so divide watts by 1000 to convert to kilowatts (20,760 wats/1000 = 20.76 kW). Record the time the motor is in operation.

What size generator do I need for a 25 hp motor?

Rule of Thumb

Electric Motor Size Minimum Generator Req’d (KVA) by Starting Method
HP KW D.O.L to KVA Size (Note 1)
15 11 37.5
20 15 50
25 19.6 60.5

How many watts does a 10 hp electric motor use?

So a 10 hp motor will need 7680 watts when operating. In one hour the motor will consume 7.680 KWatt hours.

How many watts makes 1kva?

Originally Answered: How many watts does 1kva equal to? Watts are a unit of power and power equals voltage multiplied by the current. So 1 kva equals 1000 volt amps, meaning volts multiplied by amps, therefore equals 1000 watts.

How many amps does a 5 hp 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
3 9 4.5
5 15 7.5
7.5 22 11
10 27 14

How many amps is 3 horsepower?

Common Horsepower to Amps Conversions

Horsepower Amps Efficiency
3 HP 20.7 A 90%
3.5 HP 24.2 A 90%
4 HP 27.6 A 90%
4.5 HP 31.1 A 90%

How do I convert hp to amps?

Knowing that we can write hp to amps formula for direct current (DC) as: I = P * 746 / (V * η) . As the SI unit of power is the watt, it’s common to convert units before estimating the amperage. A rule of thumb states that you should multiply the power in hp by 746 to get the power in watts.
