1. What is the Three Phase Power Formula?

The three phase power formula converts electrical power (in amps and volts) to mechanical power (in horsepower) for three-phase AC motor systems. It accounts for power factor and efficiency to provide accurate horsepower calculations.

2. How Does the Calculator Work?

The calculator uses the three phase power formula:

\[ HP = \frac{I \times V \times \sqrt{3} \times PF \times Eff}{746} \]

Where:

\( I \) — Current in amperes (A)
\( V \) — Voltage in volts (V)
\( \sqrt{3} \) — Square root of 3 (approximately 1.732)
\( PF \) — Power factor (dimensionless, 0-1)
\( Eff \) — Efficiency (dimensionless, 0-1)
746 — Conversion factor from watts to horsepower

Explanation: The formula calculates the actual mechanical power output of a three-phase motor by accounting for electrical input power, power factor, and motor efficiency.

3. Importance of Horsepower Calculation

Details: Accurate horsepower calculation is crucial for motor selection, sizing electrical components, determining load capacity, and ensuring proper system design in industrial and commercial applications.

4. Using the Calculator

Tips: Enter current in amps, voltage in volts, power factor (typically 0.8-0.95), and efficiency (typically 0.8-0.95). All values must be positive numbers within their respective valid ranges.

5. Frequently Asked Questions (FAQ)

Q1: Why is power factor included in the calculation?
A: Power factor accounts for the phase difference between voltage and current in AC circuits, representing the ratio of real power to apparent power.

Q2: What is a typical power factor value?
A: For three-phase motors, power factor typically ranges from 0.8 to 0.95, depending on motor design and load conditions.

Q3: How does efficiency affect the calculation?
A: Efficiency represents the ratio of mechanical power output to electrical power input, accounting for losses due to heat, friction, and other factors.

Q4: When should this formula be used?
A: This formula is specifically for three-phase AC motor systems. Single-phase systems use a different calculation method.

Q5: What are common applications of this calculation?
A: Motor sizing, electrical system design, industrial equipment selection, and verifying motor performance specifications.
