Torque and Power Calculator
Solve for torque in N·m, power in kW, or rotational speed in rpm from the other two values.
How it works
T = 9550P / n; P = Tn / 9550; n = 9550P / T
At 5.5 kW and 1,450 rpm, torque is 36.22 N·m.
FAQ
Which power should I enter?
Use mechanical shaft power in kW, rather than electrical input power.
Why use 9550?
It is the rounded conversion factor between kW, rpm, and N·m.
Can I enter zero speed?
Zero speed cannot determine torque from power because the formula divides by speed.
