Our 1 hp (standard) example UST1102 motor above will cost between $1-$5 per day, depending on what your power company charges per kWh, and on how many hours per day the pump is running, which changes within the season.

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

If the motor is fully loaded, it will provide output power of 1 HP = (1 X 0.746) kW = **0.746kW**. Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW.

## How much does it cost to run a hp 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 much does it cost to run a motor?

monthly cost of running the motor – including that motor’s share of demand charges and taxes as well as its kWh consumption. In our example, if the average cost of kWh is 11.2 cents, then the cost of running this 20HP motor would be 4230 x 0.112, or **$474 per month**.

## How is motor running cost calculated?

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 many kW is a 5HP motor?

Three Phase Motors

MOTOR RATING | HP | APPROX. F.L.C. AT LINE VOLTAGE |
---|---|---|

3.7 kW |
5 | 15 |

4.0 kW | 5.5 | 16 |

5.5 kW | 7.5 | 20 |

7.5 kW | 10 | 27 |

## 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 electricity does a 30 hp motor use?

RE: power consumption by 30 hp motor

a 30 Hp pump, if loaded to 65%, will draw 14.54kW, 8 pumps will draw 116.37kW, and in one hour that is **116 kWH**. The electric demand, kW, will also be 116.

## How much does it cost to run a 15 hp motor?

15 HP means it will be around **12 kW**, (as per the name plate details mentioned by the motor manufacturers ), so 12 kilo watts, running for 1 hour means it will be 12 kwh, as 1 kwh is equal to one unit, so total energy consumption is 12 units for 1 hour period for the 15 HP MOTOR, assuming that it was drawing full load …

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

If the motor actually delivers 20 horsepower (hp) of mechanical power, then the motor will draw **49 amps**.

## How much does it cost to run a 10 hp motor?

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. If the units are charged at 10 cents each then then that equates to 10x 7.680 / 100 Dollars = **76.8 cents**.

## How much power does a 7.5 hp motor consume?

Let us assume that motor is operating at full load so it will consume 7.5 hp or 5.59 or **5.6 kW approx**. Let us assume motor has efficiency of 90 %, motor at full load gives around 90 % efficiency, so the power input to motor is 5.6/0.9=6.22 kW. Energy consumption in 2 hrs = 6.22×2=12.44 KWh or 12.44 unit.

## How much electricity does a 40 hp motor use?

This gives a total power of about 40KWH per hour, so the use would be about 40*24KWH = **960KWH per day** of use at rated 40HP output power.

## How much does it cost to run a 25 hp motor?

Re: Cost to operate a 25 HP Motor…

08 = **$1.488 per hour**.

## How much does it cost to run 1000 watts per hour?

So, a 100-watt bulb would only cost $0.84 per hour if electricity cost $8.40 per kWh. In reality, electricity costs somewhere between $0.05 and $0.50 per kWh.

…

How much does 1000w cost per hour?

Appliance | Typical Consumption Per Hour | Cost Per Hour (at 10 cents per kilowatt-hour) |
---|---|---|

Electric range burner | 1,000 watts | 10 cents |

## How is electricity cost calculated?

**How do I calculate kWh for appliances?**

- Daily Kilowatt-hours (kWh)
- For the TV example:
- Daily costs = kWh x Electricity rate.
- The daily energy costs for that TV would be of:
- To calculate the annual costs, you would only need to multiply the daily costs by 365.
- First, we need to find out the kWh of such a heater:
