Formula:
The formula to calculate the Horsepower (HP) of a DC motor is derived from electrical power (Watts) and mechanical power conversion:
HP = (V × A × Eff) / 746
- HP = Horsepower
- V = Voltage (Volts)
- A = Current (Amperes)
- Eff = Efficiency (as a decimal, e.g., 0.85 for 85%)
- 746 = Conversion factor from Watts to Horsepower (1 HP = 746 Watts)
This formula allows you to understand the mechanical output power of your DC electric motor based on its electrical input and inherent efficiency.
