How much does it cost to run a 5hp electric motor?

How much electricity does a 5 hp motor use?

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 current does a 5hp motor draw?

Example: A 5 HP motor at 230V, 3PH is12. 4 amps.

How much electricity does an electric motor use?

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.

How much does it cost to run a motor?

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 do you calculate the full load of a 5 hp motor?

Full load current I, I =P. / 1.732 * V Amps.

How much electricity does a 0.5 hp motor consume?

1 unit = 1 kilowatt-hour, i.e. when an electrical appliance consumes 1 kilowatt of power for one hour. So, 0.5 HP for 8 hours = 373 × 8 = 2984 Watt-hour which is equal to 2984/1000= 2.984 units.

Can 5 hp motor run on single phase?

5hp single phase output variable frequency drive with cheap price, running your single phase motor in variable speeds. GoHz single phase output VFDs work for both L-N-G motors and split phase (L1-L2, +N, G) motors. …

What is full load current?

Definition of ‘full load current’

A full load current is the largest current that a motor or other device is designed to carry under particular conditions. … A full load current is the largest current that a motor or other device is designed to carry under particular conditions.

How do you calculate the power of an electric motor?

By taking the voltage and multiplying it by the associated current, the power can be determined. A watt (W) is a unit of power defined as one Joule per second. For a DC source the calculation is simply the voltage times the current: W = V x A.
