Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Arrangements for starting electric motors or dynamo-electric converters > for starting dynamo-electric motors or dynamo-electric converters > for starting an individual DC motor
CPC:
Arrangements for starting electric motors or dynamo-electric converters (starting of synchronous motors with electronic commutators H02P6/20, H02P6/22; starting dynamo-electric motors rotating step by step H02P8/04; vector control H02P21/00) > for starting dynamo-electric motors or dynamo-electric converters > for starting an individual DC motor
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
