SECTION H – ELECTRICITY


H 02GENERATION, CONVERSION, OR DISTRIBUTION OF ELECTRIC POWER


H 02 NELECTRIC MACHINES NOT OTHERWISE PROVIDED FOR


Notes

(1)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.

(2)Attention is drawn to the Notes following the titles of class B81 and subclass B81B relating to "micro-structural devices" and "micro-structural systems". [7]

(3)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 subclasses H01L, H01M, H02K, H04R.
