Quickly calculate the horsepower (HP) of any electric motor using our free online tool. Input voltage, current, power factor, and efficiency to get instant and accurate motor output power results. Ideal for engineers, electricians, and hobbyists seeking precise motor performance data.
Formula:
The horsepower (HP) of an electric motor is calculated using its electrical input parameters and efficiency with the following formula:
HP = (V × I × PF × η) / 746
- V = Voltage (in Volts)
- I = Current (in Amperes)
- PF = Power Factor (unitless, typically between 0 and 1)
- η = Efficiency (unitless, expressed as a decimal, e.g., 0.85 for 85%)
- 746 = Conversion factor (approx. 1 HP = 746 Watts, or 0.746 kW)
This formula converts the electrical input power (V × I × PF) into mechanical output horsepower, accounting for the motor's efficiency.
