GENERATION, CONVERSION, OR DISTRIBUTION OF ELECTRIC POWER
 H02N
ELECTRIC MACHINES NOT OTHERWISE PROVIDED FOR
 H02N

Note(s)

  1. This sub-class deals with (a) electrostatic generators, motors, clutches, or holding devices, (b) other non-dynamo-electric generators or motors, (c) holding or levitation devices using magnetic attraction or repulsion, and (d) arrangements for starting, regulating, braking, or otherwise controlling such machines unless in conjoint operation with a second machine.
  2. Specific provision exists for generators, motors, and other means for converting between electric and other forms of energy, e.g. in sub-classes H01L, H01M, H02K, H04R.
