What is the formula for power required?
Standard Electrical Formulas Used for Power Consumption Calculations
| TO DETERMINE: | SINGLE-PHASE | DIRECT CURRENT |
|---|---|---|
| Kilowatts | I x E x PF 1000 | I x E 1000 |
| Horsepower | I x E x ïF x PF 746 | I x E x ïF 746 |
| Amperes (when HP is known) | HP x 746 E x ïF x PF | HP x 746 E x ïF |
| Amperes (when kW is known) | KW x 1000 E x PF | KW x 1000 E |
How do you calculate the power consumption of a 1hp motor?
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 do you calculate the KW of an electric motor?
Multiply the motor voltage by the full-load current. The result is in watts. Divide watts by 1,000 to give kilowatts. For example, 230 volts x 20 amps = 4,600 watts; 4,600 watts divided by 1000 = 4.6 kilowatts.
How do you find the wattage of a motor?
Steps
- The number of watts is equal to amps multiplied by volts. That’s it!
- For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for power).
- This is why watts are sometimes called volt-amps.
How do you find the voltage of a motor?
A simple model for a DC motor is V=R∗i+e, where V is the terminal voltage, R is the motor resistance, and e is the back-emf voltage.
How much power does a 1 kW motor use?
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 do you calculate power kW?
To convert amps to kilowatts the power formula can be used, which states that I = P ÷ E, given that P is the power in watts, I is current in amps, and E is voltage in volts. Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts, divided by 1,000.
How can I calculate the power of an electric motor?

How do you calculate the RPM of an electric motor?
Write down the rated RPM of your motor; for example, 5000 RPM. Write down the ratio of the speed reducer; for example, 12:5. Calculate the reduction by dividing 12 by 5, which equals 2.4. The RPM of the assembly is the RPM motor divided by the reduction.
How is the RPM of an electric motor is determined?
In most cases, you can look inside the motor and count the number of poles in the winding; they are distinct bundles of wire evenly spaced around the stator core. The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor.
How do you calculate the power of a motor?
Motors supposed to do some work and two important values define how powerful the motor is. It is motor speed and torque – the turning force of the motor. Output mechanical power of the motor could be calculated by using the following formula: Pout = τ * ω. where Pout – output power, measured in watts (W);
