Instantly calculate the torque of an electric motor using its power and rotational speed. This tool is essential for motor sizing, system design, and understanding mechanical output. Get accurate results for engineering projects, robotics, and industrial applications quickly.
Formula:
The fundamental formula to calculate electric motor torque (T) from power (P) and rotational speed (N) is:
T (N·m) = (P (W) × 9.5488) / N (RPM)
Where:- T = Torque (Newton-meters)
- P = Power (Watts)
- N = Rotational Speed (Revolutions Per Minute)
- 9.5488 = Constant derived from 60 / (2 × π), used for converting power in Watts and speed in RPM to torque in N·m.
