How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Mechanical shaft power | kW | Delivered mechanical power at this shaft, not motor electrical input. |
| Shaft speed | rpm | Operating speed at the same shaft where power is specified. |
Method and formulas
- Angular speed = 2 × π × RPM / 60.
- Torque (N·m) = power (kW) × 1000 ÷ angular speed.
- Example: 5 kW at 1500 rpm corresponds to 31.830989 N·m.
Limitations
- Steady mechanical power only; no start-up, shock, stall or duty-cycle rating.
- Efficiencies must be applied before entering output shaft power.
- Example values are illustrations. Replace them with values for your actual task.
Typical uses
- motor torque
- shaft power
- rotational speed
Who it is for
- Designers
- Maintenance teams
What you get
- Shaft torque
- Angular speed
- Mechanical power
Interpreting the result
- Use the actual torque-speed envelope for drive selection.
