DIFF Subgroup
H02K 19/04 for single-phase current
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Synchronous motors or generators > Synchronous motors > for single-phase current
CPC:
Synchronous motors or generators (having permanent magnets H02K21/00) > Synchronous motors > for single-phase current
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
