for starting an individual synchronous motor

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 synchronous 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 synchronous motor

Of 4 combined children, 3 exist in both systems.

1 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.
