DYNAMO-ELECTRIC MACHINES (measuring instruments G 01; dynamo-electric relays H 01 H 53/00; conversion of dc or ac input power into surge output power H 02 M 9/00; loudspeakers, microphones, gramophone pick-ups or like acoustic electromechanical transducers H 04 R)
Notes
(1)
This subclass covers the structural adaptation of the machines for the purposes of their control.
(2)
This subclass does not cover starting, regulating, electronically commutating, braking, or otherwise controlling motors, generators or dynamo-electric converters, in general, which are covered by subclass H 02 P.
