DYNAMO-ELECTRIC MACHINES (dynamo-electric relays H01H53/00; conversion of DC or AC input power into surge output power )

Introduced: September 1968

Description

H02K covers rotating electrical machines that convert mechanical energy to electrical energy (generators) or electrical energy to mechanical energy (motors). This subclass encompasses DC machines, AC induction motors, synchronous machines, and specialized motor types including stepper motors and permanent magnet machines. The classification includes design aspects such as windings, cooling systems, magnetic circuits, and structural components of dynamo-electric machines. Adjacent classes H02P (electric machine control) and H02M (power conversion) address operational control and power supply aspects respectively, rather than the machine construction covered here.
