CPC: Devices for sensing speed or position, or actuated thereby (specially adapted for machines having non-mechanical commutating devices H02K29/06, H02K29/14)

Full Title

Full titles differ between systems:

IPC:

Structural association of dynamo-electric machines with electric components or with devices for shielding, monitoring or protection > for measuring, monitoring, testing, protecting or switching > Devices for sensing speed or position, or actuated thereby

CPC:

Structural association of dynamo-electric machines with electric components or with devices for shielding, monitoring or protection (casings, enclosures or supports H02K5/00) > for measuring, monitoring, testing, protecting or switching (rectifiers H02K11/04; power electronics H02K11/33) > Devices for sensing speed or position, or actuated thereby (specially adapted for machines having non-mechanical commutating devices H02K29/06, H02K29/14)

Additional Content IPC

Motors or generators having non-mechanical commutating devices with position sensing devices Motors or generators having non-mechanical commutating devices with speed sensing devices

IPC and CPC are identically structured here. All 4 subcodes exist in both systems.

IPC defines codes here since 2016.
