Impact of Motor Stator Winding Faults on Common-Mode Current (2110.02427v1)
Published 6 Oct 2021 in eess.SY, cs.SY, and physics.class-ph
Abstract: This paper investigates the influence of different motor stator failures on the common-mode (CM) current. The stator winding failures will affect the motor's CM impedance, and also increase the unbalance of the differential-mode (DM) noise path. The experimental results show that the former will increase the CM current induced by the CM noise source, while the latter will cause the DM current induced by the DM noise source to be converted into the CM current.
