T = torque (N·m)
Power, speed and torque
Converts transmitted mechanical power and rotational speed to torque.
VERIFIED FORMULA RECORD
T = 60P/(2πN) = 9550P(kW)/N(rpm)
Converts transmitted mechanical power and rotational speed to torque.
Variables and units
P = mechanical power (W or kW)
N = speed (rpm)
Conditions and limitations
- Steady mechanical power transmission
- Power is transmitted at the stated shaft speed
