using AC supply for only the rotor circuit or only the stator circuit

Introduced: January 2016

Full Title

Full titles differ between systems:

IPC:

Arrangements or methods for the control of AC motors characterised by the kind of supply voltage > using variable-frequency supply voltage, e.g. inverter or converter supply voltage > using AC supply for only the rotor circuit or only the stator circuit

CPC:

Arrangements or methods for the control of AC motors characterised by the kind of supply voltage (of two or more motors H02P5/00; of synchronous motors with electronic commutators H02P6/00; of DC motors H02P7/00; of stepping motors H02P8/00) > using variable-frequency supply voltage, e.g. inverter or converter supply voltage > using AC supply for only the rotor circuit or only the stator circuit

No child classifications to compare. This is a leaf node in both IPC and CPC.
