Description
H02P encompasses control and regulation systems for electric motors, generators, and dynamo-electric converters, as well as control of transformers, reactors, and choke coils. This includes speed control, torque regulation, power factor correction, starting circuits, braking systems, and protective devices for rotating electrical machinery and passive power components. The classification covers analog and digital control methods, feedback mechanisms, and conversion of electrical parameters to achieve desired operational characteristics across industrial, transport, and utility applications.
Scope Notes
Glossary: Control Controlling means influencing a variable in any way, e.g. changing its direction or its value (including changing it to or from zero), maintaining it constant, limiting its range of variation Regulation Regulating means influencing a variable in any way, e.g. changing its direction or its value (including changing it to or from zero), maintaining it constant, limiting its range of variation | Limiting references: Arrangements for starting, regulating, electronically commutating, braking, or otherwise controlling electric machines not otherwise provided for Arrangements for controlling electric generators for charging batteries Arrangements for merely turning on an electric motor to drive a machine or device, e.g.: vacuum cleaner, vehicle starter motor ,
