NOTES

  • This subclass covers the structural adaptation of dynamo-electric machines for the purpose of their control.
  • This subclass does not cover starting, regulating, electronically commutating, braking, or otherwise controlling motors, generators or dynamo-electric converters, in general, which is covered by subclass H02P.
  • Attention is drawn to the Notes following the titles of class B81 and subclass B81B relating to "microstructural devices" and "microstructural systems".
  • Group H02K 16/00 takes precedence over groups H02K 17/00 - H02K 53/00.
    {This Note corresponds to IPC Note (1) relating to H02K 17/00 - H02K 53/00.}
  • {In this subclass, it is desirable to add the indexing codes of H02K 2201/00-H02K 2213/12.}
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.
