SECTION H — ELECTRICITY

|  | H02 |
GENERATION, CONVERSION, OR DISTRIBUTION OF ELECTRIC POWER

|  | H02N |
ELECTRIC MACHINES NOT OTHERWISE PROVIDED FOR

|  | H02N |
Note(s) This sub-class deals with (a) electrostatic generators, motors, clutches, or holding devices, (b) other non-dynamo-electric generators or motors, and (c) arrangements for starting, regulating, braking, or otherwise controlling such machines unless in conjoint operation with a second machine. Specific provision exists for generators, motors, and other means for converting between electric and other forms of energy, e.g. in sub-classes Fulltext... Hierarchy... Expanded...H01L, Fulltext... Hierarchy... Expanded...H01M, Fulltext... Hierarchy... Expanded...H02K, Fulltext... Hierarchy... Expanded...H04R.
