## How much does it cost to run a 3HP motor?

A reasonable approximation is 1 HP is 0.75 kW. So a 3 HP motor will be using 3 * 0.75 = 2.25 kW. This assumes there are no losses. Running the motor for 5 hours a day will use 2.25 * 5 = 11.25 kWH per day.

## How much power does a 3 HP electric motor use?

Approximate Running Wattage

Approximate Starting Wattage Approximate Running Wattage
Capacitor Start Induction Run 1 1/2Horsepower 4200 1600
Capacitor Start Induction Run 2 Horsepower 5100 2000
Capacitor Start Induction Run 3 Horsepower 6800 3000
Capacitor Start Induction Run 4 Horsepower 9800 4800

## How many units of electricity will be consumed if we run a 3 HP 1 phase motors for 24 hours?

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. Edit 1: In above solution, it has been assumed that mechanical output is equal to the electrical input (No Losses).

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

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. 4 motors consumes = 2.984 × 4 = 11.936 units in 8 hours.

## How fast is 3 horsepower?

To give you a simple reference, a 3 hp electric outboard can push a 12 ft boat with 150 kg (331 lbs) load at a max speed of 9 km/h (5.6 mph). That’s to say the 3 hp outboard motor can provide more than sufficient propulsion for a 10 ft tender or work as an auxiliary power for a daysailer of up to 1.5 tonnes (3307 lbs).

## How much does it cost to run a 3/4 HP motor?

The electric cost would then be about 12 cents an hour, or \$2.83/day or about \$84.81 for a 30 day month, or about \$1032 for a 365 day year.

## Can you run a 3 hp motor in single phase?

Essentially all you need to do is wire the single phase power to the input side of your variable frequency drive and then wire the three phase power of your motor to the output section of the drive. That’s it!

## How many kW does a 3hp motor use?

A 3 phase electric motor drawing 20.76 kW for 173.3 hours per month will use 3771.7 kw/hours of electricity per month.

## How much electricity is consumed if I run a 1 hp motor in 3 phase for 1 hour?

Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW. 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 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 much electricity does a TV consume?

Most LED TV’s has rated power between 60 watt to 150 watt. Generally speaking larger the screen size higher is the rated power. A 100 watt TV running for 12 hours everyday will consume 1200 watt hours = 1.2 kWh (units) of electricity in a day and 36 kWh of electricity in the entire month.

## How much electricity does a 2 hp motor consume?

If it is for 2 hours, then 1.49KW × 2hr = 2.98 KWh. This is how the energy( KWh)consumed by the motor is determined.

## How much electricity does a 1.5 hp motor use?

1.5 hp = 1 kw =0.3 kwh for 20 minutes per day. Thus the energy required per day is = 1.119/3 = 0.373 kWh.

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

typical electricity consumption is 746 watts per single Horse-power. so 2 HP = 1.48 Kw per hour of operation.
