Torque (Nm) to Horsepower (HP) Calculation:

Motor Power P(HP) is equal to the torque T(Nm) in Newton meter times of speed N(rpm) divided by 7127.

The motor power P(HP) = T(Nm)*N(rpm)/ 7127

P(HP) = 0.000140304 x T(Nm)*N(rpm)


A motor can provide 144Nm at 1480 rpm. Calculate the motor rating in horsepower.

Use our torque to HP conversion formula

HP = 0.0001403 * 144 * 1480

Horsepower = 29.9 HP, approximately 30 HP
