To calculate the horsepower of an electric motor, use this formula: volts × amps × rated efficiency ÷ 746 watts.
What is hp in electric motor?
Power is in general rated in watt (W) or horsepower (hp). The old imperial unit horsepower is equal to 746 watts (0.745 kW) or 33000 lb ft per minute (or 550 lb ft per second). The unit of electric power – 1 watt – is equal to the power produced by an electrical current of 1 amp at a potential difference of 1 volt.
How do you calculate the horsepower of an electric motor?
The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.
What is the highest horsepower electric motor?
