Formula
P = M × n / 9550
n = P × 9550 / M
P = Power [kW]
n = Speed [min⁻¹]
9550 = conversion constant (60 × 1000 / 2π ≈ 9549.3)
Example Calculation
Motor with P = 7.5 kW at n = 1,450 min⁻¹:
M = 7.5 × 9,550 / 1,450 ≈ 49.4 Nm
Note: The formula applies to mechanical continuous power. For startup torque and thermal limit torque, additional factors must be taken into account.

Looking for the right motor for the calculated torque?
Torque, speed and power are settled — what decides the selection now is frame size, speed range, protection class and how the motor connects to the gearbox. Carry your values into the enquiry and we will suggest specific types from our motor and gearbox range.
