摘要:
Induced currents in a multi-phase AC motor may be attenuated by operating the multi-phase AC motor with an AC choke surrounding an AC bus providing multi-phase AC voltage to multi-phase AC stator windings in a stator, wherein the AC choke may include an effective bandwidth at least covering resonant frequencies of a capacitance between the multi-phase AC stator windings and the stator or a frame of the AC motor.
