Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Electric machines in general using piezoelectric effect, electrostriction or magnetostriction > producing rotary motion, e.g. rotary motors

CPC:

Electric machines in general using piezoelectric effect, electrostriction or magnetostriction (generating mechanical vibrations in general B06B; piezoelectric, electrostrictive or magnetostrictive devices in general H10N30/00) > producing rotary motion, e.g. rotary motors

CPC subdivides this area 3x more granularly than IPC with 5 additional codes.

5 codes are CPC-only extensions.

IPC defines codes here since 1995.
