How do you calculate the kW of a 3 phase motor?

How do you calculate the kW of a 3 phase motor?

For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000.

How do you calculate the kW of a motor?

Multiply the motor voltage by the full-load current. The result is in watts. Divide watts by 1,000 to give kilowatts. For example, 230 volts x 20 amps = 4,600 watts; 4,600 watts divided by 1000 = 4.6 kilowatts.

How do you find the full load of a 3 phase motor?

Look at the above formula, the three-phase full load current is equal to Power divided by the 3 times of product of line to neutral voltage and power factor. Here three-phase full load current is equal to the power divided by 1.732 times of line to line voltage and power factor.

What is kW rating of motor?

Motor is rated in kW since it specifies the capacity of the motor to drive its load. It is the active power (kW) that is of interest when a motor drives a load. The motor converts the active power that it draws from the mains into mechanical power that the load consumes/demands.

How many kW is a 5hp motor?

In those countries where the Imperial system is practiced, mechanical or imperial horsepower is used, which is approximately equal to 745.7 watts….Hp to kW Conversion Table.

Horsepower	Kilowatts	Rounded Kilowatts
1 hp	0.745699872 kW	1 kW
5 hp	3.72849936 kW	4 kW
10 hp	7.45699872 kW	7 kW
15 hp	11.18549808 kW	11 kW

How many kW is a 10 hp motor?

Horsepower (metric) to Kilowatt Conversion Table

Horsepower (metric)	Kilowatt [kW]
5 horsepower (metric)	3.67749375 kW
10 horsepower (metric)	7.3549875 kW
20 horsepower (metric)	14.709975 kW
50 horsepower (metric)	36.7749375 kW

Which is bigger kW or HP?

To convert kilowatts to horsepower, we multiply the number of kilowatts by 1.34. The result is that 80 kilowatts is roughly equivalent to 107 horsepower.

How many kW is a 3HP motor?

How many kW is a 3hp motor?

Horsepower (metric)	Kilowatt [kW]
1 horsepower (metric)	0.73549875 kW
2 horsepower (metric)	1.4709975 kW
3 horsepower (metric)	2

How much electricity does a 3 HP motor use?

If the motor is fully loaded, it will provide output power of 3HP = (3 X 0.746) kW = 2.24 kW. Electrical input power = output power / (Efficiency /100). Unit consumed = Power in kW X numbers of hours of operation. = 59.76 units.

How much energy does a 5 hp motor deliver in 2 hours?

If 5hp motor run for one hour than 3.73 unit consume per hour similarly for two hour it will be 3.73*2=7.46 unit.

How much electricity is consumed if I run a 1 hp motor in 3 phase for 1 hour?

Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW. So, the consumed units of electricity = Power in kW X numbers of hours of operation = 0.83 units (assuming the motor is running for an hour).

How much electricity does a 1hp motor use?

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 much electricity does a 100 hp motor use?

Expect actual operating costs to vary. For example, a 460-volt, three-phase, standard efficiency 100 HP motor operating under full load for 8,760 hours per year will probably cost just over $48,000 per year to operate at an electric rate of $0.10 per kWh.

How many horsepower is 1000w?

Watts to horsepower conversion table

Watts (W)	Mechanic horsepower (hp(I))	Metric horsepower (hp(M))
700 W	0.938715 hp	0.951735 hp
800 W	1.072817 hp	1.087697 hp
900 W	1

How much power does a 20 hp motor use?

In our 20 hp motor example, let’s say we measure 226, 230 and 234 volts, giving an average of 230 volts.

How many amps does a 1 HP 3 phase motor draw?

1-1/2	20	6.6
2	24	7.5

How do I convert kVA to kW?

The kW to kVA Formula: Apparent power (kVA) x power factor (pf) = actual power (kW) e.g. 100 kVA x 0.8 = 80 kW.
