How do you calculate kWh of a motor?

How do you calculate kWh of a motor?

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.

How do you calculate the power of a motor?

Power = (Force x Distance) / Time For electric motors, power or horsepower can be calculated from the torque and speed. For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below.

How much electricity does a 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. In one hour, it will use 3728.5 kilowatt-hours. Of course, no motor is 100% efficiency, so the motor will actually consume somewhat more power than this.

How do you calculate power consumption of a motor per hour?

Electric Motor power consumption Formula: The total power consumption E(kWh) is equal to 0.746 times of multiplication of total operating hours t(h) in hour, the rated power P(HP) in HP and the X percentage of the load. Total Power consumption = 0.746 * Horsepower * load percentage * Operating Hours.

How many kwh does a 10 hp motor use?

125×2=0.25KWH. There 746 watts for every 1 horse power. So a 10 hp motor will need 7680 watts when operating. In one hour the motor will consume 7.680 KWatt hours.

How do you calculate motor power from RPM?

How to Calculate Motor RPM. To calculate RPM for an AC induction motor, you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM.

How many kiloWatts does a 50 hp motor use?

So — 37,300 Watts / 0.92 = ~ 40,500 Watts is required to be input to the motor to get the 50 HP output. In terms of kiloWatts (kW), — the terms that your electric company charges you — this is approximately 40.5 kW.

How many kwh does a 1hp motor use?

746 KWH
The 1 HP motor consumes 746 Watts regardless of how many hours it is running. Watt and HP are not units of energy. It will consume in 1 hour. 746 KWH of energy.

How much electricity does a 2 hp motor consume?

If a 2 horse power motor is doing 2 horsepower of work then in the load about 1500 Watts of energy is used in the load.

How much electricity does 1 hp motor consume per hour?

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.
