Inner rotors

Introduced: January 2022

Full Title

Full titles differ between systems:

IPC:

Details of the magnetic circuit > characterised by the shape, form or construction > Rotating parts of the magnetic circuit > Rotor cores with permanent magnets > Inner rotors

CPC:

Details of the magnetic circuit (magnetic circuits for relays H01H50/16) > characterised by the shape, form or construction > Rotating parts of the magnetic circuit > Rotor cores with permanent magnets > Inner rotors

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 2022.
