## How do you calculate the power consumption of a 3 phase motor?

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 many amps does a 1 HP 3 phase motor draw?

The tables below are intended to be a general guide for AC motor Full Load Amperes. Always use the F.L.A. written on the motor nameplate first if it is available….AC Motor Full Load Amperes.HP110-120 Volts1/29.84.93/413.86.911681.5201010 more rows

## How much power does a 50 hp electric motor use?

For our purposes, assume the motor has an efficiency of 92% ( or 0.92). So divide the output (50 HP) by the efficiency (0.92), to get the energy required to be input into the motor, to get 50 HP. So — 37,300 Watts / 0.92 = ~ 40,500 Watts is required to be input to the motor to get the 50 HP output.

## How many kW is a 20 hp motor?

There is also metric horsepower which has been used in Europe since the beginning of the 19th century. It is equivalent to roughly 735.5 watts….Hp to kW Conversion Table.HorsepowerKilowattsRounded Kilowatts10 hp7.45699872 kW7 kW15 hp11.18549808 kW11 kW20 hp14.91399744 kW15 kW25 hp18.6424968 kW19 kW16 more rows

## What should motor overloads be set at?

The required overload protection setting for motors is 125% of their full-load current according to the NEC, but make sure you read the overload relay instructions as well. Some manufacturers have the 125% setting built in, which means you must set the overload protection at the motor’s nameplate current.

## How much current does a 3 HP motor draw?

## How much electricity does a 1 hp motor use?

Here, we have a 1 HP motor. So, 1 HP for 24 hour = 746×24= 17904 Watt-hour which is equal to 17904/1000= 17.904 units. Hence, 17.904 units of Power will be consumed by the 1 HP motor when run continuously for 24 hours.

## How is motor horsepower calculated?

Horsepower (hp) = voltage x amperage x % EFF x power factor x 1.73/746.Voltage is the average of the three voltages measured: (A-B + A-C + B-C)/3.Amperage is the average current of the three-phase measured: (A+B+C)/3.% EFF is motor efficiency per motor nameplate.More items…

## What is HP power?

Horsepower, the common unit of power; i.e., the rate at which work is done. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute—that is, the power necessary to lift a total mass of 33,000 pounds one foot in one minute.

## How many units of electricity will be consumed if we run a 3 HP 3 phase motors for 24 hours?

59.76 unitsElectrical input power = output power / (Efficiency /100). Unit consumed = Power in kW X numbers of hours of operation. = 59.76 units. Hence units burnt (consumed) by 3 HP motor in 24 hours will be 59.76, if the motor efficiency is 90% and motor is fully loaded.

## How much power does a 2 hp motor use?

## How much electricity does a 5 hp motor consume?

Output mechanical energy: 5 HP X 746 Watts = 3,730 Watts or 3.73 kW. As the output mechanical energy is the result of the motor performing at 80% efficiency, the power consumed by the 5 HP motor will be 3.73 kW X 100 ÷ 80= 4.66 kW.

## How much power does a 1.5 hp motor use?

1hp equal to 750 watts so 1.5. hp equal to 1125 watts .

## How do you calculate electricity consumption?

How to calculate my energy consumptionDevice Wattage (watts) x Hours Used Per Day = Watt-hours (Wh) per Day.Device Usage (Wh) / 1000 (Wh/kWh) = Device Usage in kWh.Daily Usage (kWh) x 30 (Days) = Approximate Monthly Usage (kWh/Month)

## How much electricity does a 1 HP pool pump use?

Our 1 hp example pump uses 1.75 Kw per hour; whereas a 2 hp motor of the same type (UST1202) would draw 2.4 Kw per hour. That’s around 24 kWh per day, or around 720 kWh per month, just running only 10 hors per day. During the heat of the summer, many pumps need to run longer to maintain clear water.

## How much power does a 20 hp motor use?

At 20 hp, P = 20*745.7 = 14,914 watt.
