H02P 6/21 Open loop start
Introduced: January 2016
Full Title
Full titles differ between systems:
IPC:
Arrangements for controlling synchronous motors or other dynamo-electric motors using electronic commutation dependent on the rotor position; Electronic commutators therefor > Arrangements for starting > Open loop start
CPC:
Arrangements for controlling synchronous motors or other dynamo-electric motors using electronic commutation dependent on the rotor position; Electronic commutators therefor (vector control H02P21/00) > Arrangements for starting (H02P6/08 takes precedence) > Open loop start
No child classifications to compare. This is a leaf node in both IPC and CPC.
