H02N
ELECTRIC MACHINES NOT OTHERWISE PROVIDED FOR [2023-02]
NOTES

  • This subclass covers:
    • electrostatic generators, motors, clutches, or holding devices;
    • other non-dynamo-electric generators or motors;
    • holding or levitation devices using magnetic attraction or repulsion;
    • arrangements for starting, regulating, braking, or otherwise controlling such machines unless in conjoint operation with a second machine.
  • Specific provision for generators, motors, or other means for converting between electric and other forms of energy also exists in other subclasses, e.g. in class H10 and subclasses H01L, H01M, H02K, H04R.
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
