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. 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 watts does a 2 hp electric motor use?
Approximate Running Wattage
| Approximate Starting Wattage | Approximate Running Wattage | |
|---|---|---|
| Capacitor Start Induction Run 1 Horsepower | 3000 | 1000 |
| 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 |
How much power does a motor consume per 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).
What is Watts in electric motor?
In most cases, the watt rating on an electric bike motor describes how much energy the motor can handle (or consume) continuously. This continuous watt rating is different from a peak watt rating that describes how much energy the motor can manage (or, again consume) for short periods of time.
How many kW is a 5hp motor?
Since one electric horsepower is equal to 0.746 kilowatts, the formula to find kilowatts is to multiply electric horsepower by 0.746. For example, here’s how to convert 5 electric horsepower to kilowatts using the formula.
How many watts does a 10 hp electric motor use?
Subject: RE: How many kilowatts /hour does 10 HP fan take? 746 watts per Hp but, rule of thumb figure 1KW per Hp to allow for efficiency losses. So 10 KWH would run a 10 Hp motor for 1 hour.
How many watts is an electric fan?
Do Fans Use a Lot of Electricity? Running a fan takes a lot less electricity than running an air conditioner; ceiling fans average at about 15-90 watts of energy used, and tower fans use about 100 watts.
How is motor wattage calculated?
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.
How much power does a 100 hp motor use?
Data Logger information imported into a spreadsheet for analysis. This 100-horsepower centrifugal pump motor, if fully loaded, should be consuming nearly 80,000 watts (80 kW).
How is motor power calculated?
Power = (Force x Distance) / Time
For electric motors, power or horsepower can be calculated from the torque and speed. For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below.
Is 350 watts enough for an ebike?
If you want to ride along a bike path and not pass by pedestrians or other cyclists without drawing attention to yourself with a loud motor, 350 watts is a good choice. More powerful motors can be quiet too, but vary by manufacturer.
How fast can a 350 watt motor go?
The 350W and 500W versions are rated as Class 3, meaning they could achieve a top speed of 28 mph.
