(Redirected from RPM)
Revolutions per minute (usually abbreviated rpm, RPM, r/min, or r·min−1) is a unit of frequency: the number of full rotations completed in one minute around a fixed axis.
Common usage for helicopters includes:
- Tail rotor RPM.
- Engine RPM
- Engine prop shaft RPM.
- N1 RPM
- Turboshaft gas generator compressor/ turbine RPM.
- N2 RPM
- Turboshaft power turbine RPM.
- Electrical RPM
- The frequency of commutation cycles of a brushless motor or ESC. A brushless motor with 6 poles (magnets) will have an electrical RPM twice that of its physical RPM.
