H02N ELECTRIC MACHINES NOT OTHERWISE PROVIDED FOR
Introduced: September 1968
Description
H02N covers electric machines and motors that do not fit within the standard categories of rotating machines, transformers, or other specifically defined electrical equipment. This subclass includes unconventional electromechanical devices such as electrostatic motors, piezoelectric actuators, magnetostrictive devices, and other electromagnetic conversion systems. It serves as a residual category for novel or specialized electric machine types that lack dedicated classification provisions elsewhere in H02. Applications include emerging technologies in micro-actuation, energy harvesting, and experimental motor designs that do not conform to traditional AC/DC motor architectures.
IPC and CPC are identically structured here. All 8 subcodes exist in both systems.
4 shared codes have differing titles between IPC and CPC.
