How do you calculate power consumption of an electric motor?

Calculate the power the motor consumes while in operation. The equation is W = AV(sqrt 3) where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). 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.

What is the formula to calculate power consumption?

Hence, the energy consumption formula or the power consumption formula is given as below: E = P*(t/1000); where E = energy measured in Joules or in kilowatt-hours (kWh), P = power units in watts, and t = time over which the power or energy was consumed.

How do you calculate electric motor kW?

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 calculate units consumed by a motor?

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. In actual, motor load will be less than full load and units consumed will be less accordingly.

How much power does a 1 hp motor consume?

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 is a kWh electricity?

Both gas and electricity consumption is measured in kWh. The unit rate you pay will vary depending upon the energy price plan you’re on, and even the region you live in, but the average cost of electricity per kWh is 14.37p, and the average gas cost per kWh is 3.80p.

What is the unit of power consumption?

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity.

What is the formula for kW?

We find the power in kilowatts P(kW) by dividing the power in watts P(W) by 1,000. Here’s the Formula for Converting Watts Into Kilowatts: P(kW) = P(W) / 1,000.

How many kW is 3phase?

The SQRT(3) is used as line voltage for 208V output is derived from using two hot conductors. For example, a 30A 3 phase unit outputting 208V would be 208 x 24 x SQRT(3)=8.6kW.
