Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for marine propulsion generators
Rotor design for shipboard use changes classification to other specialized applications.
If designed for aircraft gas turbine auxiliary power units
APU generator components may classify under turbojet/turboprop parts in 8411.
If generic rotors adaptable to multiple generator types
Non-aircraft-specific rotors go to residual electric motor parts subheading.
