Power Transmission Calculator vs Shaft Power Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Power Transmission Calculator
Converts torque (N·m) and rotational speed (rpm) into mechanical power in kilowatts. Use it when sizing motors, drives, or shafts, or when checking whether a drivetrain can handle a given load without overheating.
- Answers
- Power (kW)
- Inputs
- Torque, Rotational Speed
Shaft Power Calculator
Calculates the mechanical power transmitted through a rotating shaft given its torque and rotational speed. Use this when sizing motors, gearboxes, or drive shafts in mechanical systems.
- Answers
- Power (W)
- Inputs
- Torque, Angular Velocity
