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.
