Quick Answer: How do you calculate the cost of an electric motor?

How is electric motor calculated?

Motor running current and voltage values should be measured and recorded on a routine basis as part of a preventive maintenance program. Use this formula to estimate motor horsepower: Horsepower (hp) = Voltage x Amerage x % EFF x power factor x 1.73/746.

How much does a electric motor cost?

How Much Does A Car Electric Motor Cost? Batteries – between $1,000 and $2,000. Other costs include travel and food. A motor vehicle can cost anywhere between $1,000 and $2,000.

How do you calculate kWh of a motor?

Electric Motor power consumption Formula:

The total power consumption E(kWh) is equal to 0.746 times of multiplication of total operating hours t(h) in hour, the rated power P(HP) in HP and the X percentage of the load. Total Power consumption = 0.746 * Horsepower * load percentage * Operating Hours.

How do you calculate the cost of a device?

Calculate Energy Cost by Appliance

  1. Multiply the device’s wattage by the number of hours the appliance is used per day.
  2. Divide by 1000.
  3. Multiply by your kWh rate.

How much does a new motor cost?

Generally, used engines on most passenger cars can be replaced for $3000-$4000 and new engines can be between $4000-$6000. Some will be more, some less. The average price of a used car is well over $8000, and if you’re looking for a model 3-4 years old, that number jumps to over $20,000.

How many kilowatts does a 50 hp motor use?


H.P. 230 V 30 kW @ Full Load
25 20.197
30 24.858
40 33.044
50 38.752

How much electricity does 1 hp motor consume per hour?

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 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 do you calculate electricity cost per kWh?

To calculate your running costs, you’ll need to convert the wattage of the appliance to kilowatts; this can be done simply by dividing your wattage by 1000. In our example, we’re dividing our 1000W radiator by 1000 to give us 1kW.

How do I calculate the power consumption of a device?

To calculate power consumption of any appliance, you have to multiply it’s wattage by the number of hours it is being used (operational hours). For example, a 1000 watt electric iron running for one hour will consume (1000 watt X 1 hour) 1000 watt hour or 1 kilowatt hour (kWh) of electricity.

How do you calculate the cost of running an electrical item?

To calculate what each device costs to run, choose an appliance and have a look at its wattage label. Multiply the wattage by the number of hours you use it and divide the result by 1,000. A very simple example is this: if you pay 17p per kWh and your microwave is 1,000 watt, it will cost you 17p to run it for an hour.
