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 is motor running cost calculated?

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 electricity does a 1hp 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 electricity does a 50 hp motor use?

For our purposes, assume the motor has an efficiency of 92% ( or 0.92). So divide the output (50 HP) by the efficiency (0.92), to get the energy required to be input into the motor, to get 50 HP. So — 37,300 Watts / 0.92 = ~ 40,500 Watts is required to be input to the motor to get the 50 HP output.

## How many units of electricity does hp motor use per hour?

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 does a 1 hp motor cost?

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. This will result in a monthly cost of $30-$150.

## How much power does a 2 hp motor use?

How many watts does a 2 HP motors have? 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 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 many solar panels do I need for 1hp motor?

You’ll need 2.2 Kilowatts for 1 HP motor.

We recommend up to twice-or-trice capacity of solar setup than motor’s rated requirement like 2-3 HP (2.2 KW) solar system to run motor a few other loads while running 1 HP water motor.

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

If the motor is loaded to 10 hp, which it probably isn’t, its drawing 746 watts per hp divided by the efficiency, probably about 90% for a motor that size or a total of 8.29 KWH for each hour it runs. At 14 cents per KWH, that would be $1.16.

## How much does 3kW cost per hour?

Electric Heating Electricity Cost Calculator

Power Rating | Per Hour | Per Day* |
---|---|---|

1500W (1.5kW) | 27.81p 1500W | £1.67 9kWh |

2000W (2kW) | 37.08p 2000W | £2.22 12kWh |

2500W (2.5kW) | 46.35p 2500W | £2.78 15kWh |

3000W (3kW) | 55.62p 3000W | £3.34 18kWh |

## How much electricity does a 10 hp motor consume?

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 horsepower is in a motor?

The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.

## How many kW is a 1.5 hp motor?

Three Phase Motors

MOTOR RATING | HP | |
---|---|---|

0.56 kW | 3/4 | 2.8 |

0.75 kW | 1 | 3.2 |

1.1 kW | 1.5 | 4.5 |

1.5 kW | 2 | 5.8 |

## How much electricity does a 3/4 hp motor use?

ELECTRIC MOTOR WATTAGE GUIDE

Motor Rating HP | Approximate Running Watts | Capacitor Motors |
---|---|---|

3/4 | 850 | 2600 |

1 | 1000 | 3000 |

1-1/2 | 1600 | 4200 |

2 | 2000 | 5100 |

## How much electricity does water motor consume?

To give you a rough estimate the average rated power of water pump is from 250 watts to 1500 watts. Smaller the water pump, less is the wattage, less is the power consumption, hence low is the discharge and head.
